Fluoridation of Public Water Systems:
Valid Exercise of State Police Power or Constitutional Violation?
The United States Supreme Court has never decided whether a state, in the proper exercise of its police power, can mandate prophylactic medication for a noncontagious disease when such disease is treatable by reasonable, less intrusive means. More specifically, the Supreme Court has never decided whether fluoridation of public water systems is a valid exercise of state police power or a constitutional violation. It is the scope of state police power and governmental involvement with the noncontagious disease of dental caries that will be explored in this Comment.
Police power is the implied constitutional authority allowing states to make laws concerning the health, safety, welfare and morals of its citizens.1 States exercise their police power when they require that students be medicated against contagious diseases, such as measles, mumps and rubella, by way of inoculations prior to attending public schools. This immunization requirement is virtually uncontested by the public because the risk of spreading communicable diseases to other students is widely recognized.2
However, states also medicate the public water systems3 with fluoride in an attempt to retard tooth decay -- a non-contagious disease,4 also known as dental caries.5 This state action has been rigorously contested by members of the public because the addition of fluoride to the public water system by municipal providers6 may have adverse consequences on the health of the general public which outweigh the benefits allegedly prodded in reducing tooth decay in children.7
Fears concerning the purity of public water sources have increased dramatically in recent years, due in part to reports of leaking landfills, corroding pipes and crumbling gasoline storage tanks tainting water supplies.8 These fears pertain not only to contaminants such as lead, nitrates, pesticides, radon and other organic chemicals that inadvertently find their way into public drinking water, but also to chlorine and fluorine, which are purposely added to public water systems.9 A public survey conducted in the late 1980s indicated that "[n]early 70 percent of Americans are worried about the quality of their drinking water . . . [with] their concern center[ing] on how water looks, tastes or smells.10
In 1992, "Americans spent more than $700 million on inhome filters" and more than $2 billion on bottled water in efforts to avoid drinking contaminated water.11 In spite of this, a common misconception is that fluoridated tap water provided by a public water system is completely safe to drink. This assumption is unwarranted because fluoridated tap water has the potential to cause adverse health consequences, including death.12
While the general public supports chlorination13 to ensure that tap water is safer to drink, there is both adamant support and unrelenting opposition to the artificial fluoridation of drinking water.14 Public debate on the issue of fluoridation began in the 1950s and continues to date, resulting in an abundance of lawsuits opposing fluoridation of public water systems.
The public support for fluoridation exists mainly because of the misconception that fluoride in drinking water and toothpaste benefits the development and overall health of the teeth of both children and adults. However, even proponents of fluoridation admit that fluoride does not provide any health benefits when ingested by an adult, while the potential exists for causing adverse health problems, such as crippling skeletal fluorosis.15 Other adverse health problems linked to fluoride include a 690% increase in bone cancer in of young males,16 a doubling of hip fractures for both older men and women,17 and infertility in women.18
Some opponents of fluoridation are of the opinion that there is no correlation between the level of fluoride in water and dental caries.19 As a matter of fact, the federal government has conceded that the purported benefit of fluoridation is limited, as it applies only to developing enamel in the teeth of children up to the age of nine.20 The problem with health laws specifically targeted at children is that children constitute only a minority of the general public because "[t]he most recent year in which a majority of families included at least one child among their members was 1982.... [C]hildren are defined as the householder's own children who are under the age of 18, have never been married, and are still living at home.21 It logically follows that persons under the age of eighteen comprise less than 50% of the U.S. population.
Therefore, state laws authorizing municipal fluoridation of water do not benefit the majority of the public, and thus do not promote the health, safety, and welfare of Americans, the majority of whom are adults.
Fluoridation of public water systems has been attacked in the courts on various constitutional grounds, but has always been upheld as a valid exercise of state police power.22 This result stems from the application of the "rational basis" test of judicial review to fluoridation laws by all of the appellate courts. The rational basis test is the least demanding form of judicial review, providing broad deference to the legislature. It merely requires that the goals sought be legitimate, and that the means chosen by the legislature be rationally related to the achievement of those goals, so as not to violate the Due Process Clause.23 To pass constitutional muster under the rational basis test, legislation cannot be arbitrary and must have a reasonable purpose which "bears a rational relationship to a [permissible] state objective."24
There is a rebuttable presumption that all legislation is constitutional, and "those challenging a statute must prove unconstitutionality beyond a reasonable doubt."25 Because of this presumption of validity, courts will generally apply the easily-satisfied rational basis test to a challenged law, unless given a reason to justify a higher standard of review. A constitutional challenge to legislation is one such reason for performing a more demanding judicial review, because the rational basis test does not apply if the statute "interferers with the free exercise of some fundamental personal right or liberty."26
The rational basis test is properly applied to legislation dealing with public health protection, such as the prevention or spread of contagious or communicable diseases.27 However, fluoridation of public water systems cannot logically rise to the level of a public health protection measure, as it is merely an attempt to prevent the disease of tooth decay, which is neither contagious nor communicable. Thus, adding prophylactic medication (fluoride) to drinking water exceeds the scope of state police power, and courts should apply the highest standard of judicial review, called "strict scrutiny" to the legislation authorizing fluoridation.
Strict scrutiny is the highest standard of judicial review that courts use to determine if a law deprived, infringed, or interfered with a fundamental constitutional right or liberty.28 To pass this test, the legislation must be narrowly tailored and necessary to achieve a legitimate, compelling state interest.29 It is first necessary to understand what constitutes a "fundamental constitutional right" in order to know when a strict scrutiny review is required. The United States Supreme Court has recently held that "[t]he forcible injection of medication into a nonconsenting person's body represents a substantial interference with that person's liberty," 30 which involves a fundamental constitutional right.
This Comment shows why, under strict scrutiny review, state laws authorizing fluoridation of public water systems should be struck down as unconstitutional since they impinge a fundamental constitutional right, the means of accomplishing fluoridation is not narrowly tailored, and there is no compelling government interest involved.31 To fully understand the detrimental effects of fluoride on the human body, one must be familiar with its chemical properties and how it has become regulated by the federal government. To accomplish this goal, Part I of this Comment examines the adverse health effects caused by fluoride ingestion and how fluoride has come to be labeled as a contaminant, poison, and most importantly, as a drug for treating a noncontagious disease.
Part II traces the regulatory attempts aimed at ensuring the provision of safe drinking water by municipalities, and explains the role of the Environmental Protection Agency in establishing contaminant levels for fluoride under the Safe Drinking Water Act. Part III examines the legal challenges to fluoridation of public water systems, noting that courts have upheld that it is a valid exercise of state police power. Part IV addresses the exercise of state police power as a basis for enacting fluoridation laws.
Further, Part IV analyzes the constitutional protection afforded to an individual in the context of fluoridation laws. Finally, Part V concludes that courts have used the wrong standard in their judicial review of statutes authorizing fluoridation, and that fluoridation laws will not pass constitutional muster under a strict scrutiny standard of review. This is because fluoridation statutes violate the constitutionally protected liberty interest to be free from unwanted medical treatment recognized by the U.S. Supreme Court in the 1990 cases, Cruzan v. Director, Missouri Dept of Health32 and Washington v. Harper.33 These two decisions have not yet been relied upon by a lower court in the constitutional analysis of fluoridation laws.
Fluoridating public water in an attempt to target children whose permanent teeth are still developing is like using a shotgun to shoot an apple off someone's head; sure, you hit the apple, but the side effects are undesirable.
I. Health Effects on the Human Body From Fluoride Ingestion
To understand why most, if not all, states have laws providing for the addition of fluoride to the public water systems and why the public opinion is split as to the benefits and harms of fluoridation, some background information on fluoride is useful. Fluoride is a binary compound,34 consisting of the element fluorine35 combined with another element, such as copper, magnesium, iron, sodium, or zinc.36 Fluorine has been estimated to be the thirteenth most abundant element in the earth's crust and is usually found only in combination with other elements, producing compounds called fluorides.37
It is crucial to note that fluorine is not an essential nutrient needed by the human body.38 Virtually all foods contain trace amounts of fluoride, but the quantity is negligible and not considered for purposes of regulating maximum fluoride levels in drinking water.39 The use of fluoride for medicinal purposes originated because it was discovered in communities where the water supply naturally contained a small percentage of dissolved fluorides that the tendency toward tooth decay in children was notably reduced.40 Accordingly, the United States Public Health Service endorsed the artificial fluoridation of public drinking water in 1950.41 Because the government is now actively involved in preventing tooth decay (a periodontal disease), it is actually practicing medicine, which is defined as "the science and art of . . . preventing disease," and fluoride may be considered a 'medicine' which is defined as "any drug or other substance used in treating disease ...."42
The decision to add fluoride to public water systems sparked controversy because "the fluoride encountered in 'natural' drinking water is calcium fluoride,"43 but artificial fluoridation is accomplished by using either sodium fluoride,44 sodium fluorosilicate,45 or hydrofluorosilicic acid.46 Sodium fluoride was the first compound used in public water systems to artificially fluoridate public water, which caused an uproar because sodium fluoride is a known poison used commercially as an insecticide, rodenticide, wood preservative and fungicide, in ceramics production, and in light metal production.47 The federal government recognizes the toxicity of sodium fluoride because it is regulated as an active ingredient in pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).48 Pesticides with highly toxic quantities of sodium fluoride in them must have the skull and crossbones symbol as well as the word poison prominently displayed on the container.49
The government promoters seeking to add fluoride to the public water systems back in the 1950s held a conference and tried to diffuse this issue by instructing those in attendance not to use the word "artificial" in conjunction with fluoridation and not to tell the public that sodium fluoride is being used because "that is rat poison."50 Instead, the public should only be told that "fluorides" are added to the water.51
This is hardly comforting because in a table of water-borne contaminants, the Environmental Protection Agency (EPA) lists fluoride between cyanide and mercury, two toxic substances that the public would certainly never tolerate to be purposely added to their water supply.52
The scientific community is sharply divided as to the detrimental effects of fluoride on the human body.53 The EPA solicited and received over 400 written public comments and held two full days of public hearings in Washington, D.C. pertaining to the issue of whether fluoride in public drinking water posed adverse health effects.54 Many professional health organizations and state officials believed that fluoride in drinking water causes no adverse health effects, but other commentators believed that it can cause serious adverse health effects, such as crippling skeletal fluorosis,55 mutagenicity,56 and oncogenicity.57 Dr. John Yiamouyiannis, an expert biochemist witness who has testified in several lawsuits challenging fluoridation statutes, authored a book entitled Fluoride - The Aging Factor.58
In this book, Dr. Yiamouyiannis describes, among other adverse health effects, how fluoride damages enzymes and interferes with collagen formation in the human body, resulting in premature aging.59 This book, along with eighty-eight other technical reports and studies, were considered by the EPA in its determination of the Recommended Maximum Contaminant Level (RMCL) for fluoride to be published in the Code of Federal Regulations (CFR).60 The EPA concluded that there was an inadequate basis to say that fluoride is oncogenic, mutagenic, or results in allergic or idiosyncratic sensitivity.61 However, the EPA acknowledged that the conclusions of the studies conflicted and that there are ongoing chronic rat and mouse bioassays designed to measure the oncogenic62 potential of fluoride, which they will reconsider when the results become available.63
The EPA did acknowledge that dental fluorosis, a condition manifested by staining and/or pitting of the teeth, can result from ingesting fluoride, but labeled it as a cosmetic effect rather than an adverse health effect within the meaning of the Safe Drinking Water Act.64 The EPA also concluded that crippling skeletal fluorosis has been thoroughly documented to be associated with the consumption of fluoridated drinking water in the U.S., and accordingly set the RMCL to protect against this adverse health effect.65 In response to public comments opposing fluoridation, the EPA emphasized that the Safe Drinking Water Act "prohibits [the] EPA from requiring the addition of any substance for preventative health care purposes unrelated to [the] contamination of drinking water," and that just because it issued final regulations does not mean that it endorses the fluoridation of public water systems.66
The federal government also regulates the ingestion of fluoride by humans in the Food, Drug, and Cosmetic Act, chapter 1, subchapter D, part 355 Anticaries Drug Products for Over-the-Counter Human Use,67 and also in chapter 1, subchapter B. part 165 Beverages.68 Fluoride used in a toothpaste, dentifrice, mouthwash, gel, or rinse is considered to be an anticaries drug, which is "[a] drug that aids in the prevention and prophylactic treatment of dental cavities (decay, caries)."69 Three sources of fluoride are used for topical application in the mouth: sodium fluoride, 70 sodium monofluorophosphate,71 and stannous fluoride.72 While the maximum permissible fluoride concentration in water is 4mg/ L, it is much higher in topical applications, depending on its form. For example, dentifrices73 contain a theoretical total fluorine concentration of 850 to 1150 parts per million (ppm)74 in a paste dosage form.75 This concentration is aimed at obtaining at least 650 ppm76 of fluoride ions,77 whereas treatment rinses78 target a fluoride ion concentration of 0.01 0.05 percent in an aqueous solution.79
The government has recognized the adverse health effects that may result from swallowing either fluoridated toothpaste or mouth rinse, and requires that warning labels be affixed to the anticaries drug products. 80 All fluoride dentifrices (tooth pastes and tooth powders) must be labeled "Warning: Keep out of the reach of children under 6 years of age. 81 The labels for rinse and gel products emphasize the importance of spitting out the solution and not swallowing it.82 This is because fluoride is very toxic, and at least one child has been killed from swallowing a fluoride jell applied by a dental hygienist.83 In summary, fluoride is neither a vitamin nor a mineral necessary for human health.84 Rather, fluorine is a highly reactive element85 used as a prophylactic drug to help prevent tooth decay in developing permanent teeth.86 Fluoride provides no benefits to adults, and ingestion of it will only result in the health problems previously mentioned.87
II. Legislative History of Safe Drinking Water
One of the first published cases attempting to ensure the safety of drinking water was Commonwealth v. Towanda Water-Works.88 In Towanda, the Pennsylvania Attorney General alleged that the public water in the borough of Towanda was impure, unwholesome, polluted, unfit for use by the public, and dangerous to their lives and health.89 The evidence as to the purity of the water was conflicting, but the jury found that the water was wholesome, 90 even though it was not pure.91 The court took judicial notice that the only possible way to obtain pure water was by distillation.92 Thus, the court held that the statute requiring "pure" water to be furnished for public consumption was to be construed to mean wholesome water, not pure in the abstract or chemical sense.93 This case laid the foundation for the first drinking water standard set by the U.S. Public Health Service.
Promulgated in 1914, this standard was designed to protect the public from acute bacterial diseases,94 and eventually led to the enactment of federal legislation in 1974 known as the Safe Drinking Water Act (SDWA).95 The Safe Drinking Water Act requires the EPA Administrator to identify waterborne contaminants and publish maximum contaminant levels (enforceable standards) and recommended maximum contaminant levels (nonenforceable health goals) for municipal providers.96 The SDWA was amended in 1986, changing the Recommended Maximum Contaminant Level (RMCL) terminology to Maximum Contaminant Level Goals (MCLG).97 The EPA Administrator must promulgate national primary drinking water regulations for contaminants which may have an adverse effect on the health of persons and which are "known or anticipated to occur in public water systems."98 The EPA issued national primary drinking water regulations for fluoride because it concluded that crippling skeletal fluorosis99 is an adverse health effect, and has been thoroughly documented to be associated with consumption of fluoridated drinking water.100
The EPA promulgated a Maximum Contaminant Level101 (MCL) for fluoride in the 1985 National Interim Primary Drinking Water Regulations, pursuant to section 1412 of the Safe Drinking Water Act.102 This interim MCL varied from 1.4 milligrams per liter (mg/L) to 2.4 mg/L, depending upon the annual average ambient air temperatures.103 This interim amount was twice the optimum fluoride concentration, and was determined to strike an appropriate balance between the occurrence of dental fluorosis104 and the prevention of dental caries.105
In response to this proposed MCL, the EPA received over 400 written public comments and held two full days of public hearings as to whether fluoride in drinking water posed adverse health consequences.106 Based upon all the information it received, the EPA set the Recommended Maximum Contaminant Level (RMCL) of fluoride at 4 mg/L,107 and subsequently set the Maximum Contaminant Level (MCL) at 4 mg/L also.108 The EPA promulgated an RMCL for fluoride because it agreed with Surgeon Generals Shapiro and Koop that adverse health effects stemming from the ingestion of fluoride include "death, gastrointestinal hemorrhage or irritation, arthralgias, and crippling fluorosis." 109 RMCLs are non-enforceable health goals which are set at levels for which there are "no known or anticipated adverse health effects" and which leave a margin of safety to protect against crippling skeletal fluorosis.110 The difference between an MCL and an RMCL is that the RMCL is supposed "to be based only on health and safety considerations while an MCL takes feasibility and cost into consideration.111
The Administrator must also promulgate the national secondary drinking water regulations, which are designed to protect the public health by controlling contaminants that "may adversely affect the odor or appearance of [drinking] water.112 These secondary regulations specify the Secondary Maximum Contaminant Levels (SMCLs) which limit those contaminants that "may adversely affect the aesthetic quality of drinking water such as taste, odor, color and appearance ...."113 Fluoride was not included in the original list of contaminants, but in 1985 the EPA Administrator proposed a SMCL of 2.0 mg/L for fluoride.114 This limit was eventually approved and incorporated into the Code of Federal Regulations (CFR).115
If the EPA's SMCL for fluoride is exceeded, but the MCL is not, the CFRs require that the municipal water provider send the following notice to all paying users, as well as to the state public health officer:
Public Notice
Dear User:
The U.S. Environmental Protection Agency requires that we send you this notice on the level of fluoride in your drinking water. The drinking water in your community has a fluoride concentration of [fill in amount] milligrams per liter (mg/L).
Federal regulations require that fluoride, which occurs naturally in your water supply, not exceed a concentration of 4.0 mg/L in drinking water. This is an enforceable standard called a Maximum Contaminant Level (MCL), and it has been established to protect the public health. Exposure to drinking water levels above 4.0 mg/L for many years may result in some cases of crippling skeletal fluorosis, which is a serious bone disorder.
Federal law also requires that we notify you when monitoring indicates that the fluoride in your drinking water exceeds 2.0 mg/L. This is intended to alert families about dental problems that might affect children under nine years of age. The fluoride concentration of your water exceeds this federal guideline.
Fluoride in children's drinking water at levels of approximately 1 mg/L reduces the number of dental cavities. However, some children exposed to levels of fluoride greater than about 2.0 mg/1 may develop dental fluorosis. Dental fluorosis, in its moderate and severe forms, is a brown staining and/or pitting of the permanent teeth.
Because dental fluorosis occurs only when developing teeth (before they erupt from the gums) are exposed to elevated fluoride levels, households without children are not expected to be affected by this level of fluoride. Families with children under the age of nine are encouraged to seek other sources of drinking water for their children to avoid the possibility of staining and pitting.
Your water supplier can lower the concentration of fluoride in your water so that you will still receive the benefits of cavity prevention while the possibility of stained and pitted teeth is minimized. Removal of fluoride may increase your water costs. Treatment systems are also commercially available for home use. Information on such systems is available at the address given below. Low fluoride bottled drinking water that would meet all standards is also commercially available.
For further information, contact [Public Water System employee's name, address, and phone number] at your water system116
The EPA has published a disclaimer in the national primary drinking water regulation for fluoride stating that: (1) they do not endorse fluoridation, even though they established an RMCL, (2) public water systems are not required to meet the RMCL, (3) states are not required to adopt the RMCL, and (4) fluoridation is a matter for state and local authorities.117
The RMCL for fluoride promulgated by the EPA is based upon the presumption that a child will drink 1.4 liters of tap water a day and that an adult will drink 2.0 liters a day.1118 However, the EPA does not admit that suppliers of water119 frequently violate the RMCL as well as the MCL for fluoride. In fiscal year 1986, 740 Public Water Systems (PWS) were in violation of fluoride levels.120 Moreover, fluoride was the second most frequently violated contaminant by Significant Non-Compliers (SNCs).121
III. Legal Challenges Against Public Water System Fluoridation
The United States Supreme Court has never decided whether a state can compel individuals to ingest fluoride through public drinking water, when fluoride can be administered by other reasonable, less intrusive means. Accordingly, some state courts have limited their constitutional analysis of fluoridation statutes, based on reasoning that since the United States Supreme Court has declined to hear any fluoridation cases, there must not be any substantial constitutional issues.122 The trial court in Paduano v. City of New York123 held that "[w]hile denials of certiorari do not constitute decisions on the merits, it is clear that the Supreme Court has repeatedly held that no substantial Federal questions are presented by objections to fluoridation."124 The court assumed, however, that the United States Supreme Court is, in effect, affirming the lower court when it dismisses the appeal.125 However, this is not true, and courts should be compelled to analyze all constitutional issues in light of the most recent Supreme Court decisions.126
A. Challenges Based on States' Lack of Authority to Fluoridate Public Water Systems
The first reported challenge to the addition of fluoride to a public water supply by a state was in De Aryan v. Butler.127 In De Aryan, a taxpayer brought suit seeking to enjoin the addition of fluoride to water furnished to San Diego.128 The basis for the challenge was that the city council exceeded its authority in enacting the fluoridation resolution.129 The De Aryan court found that the State Board of Public Health was part of the Department of Public Health and thus had the "power to formulate policies affecting public health, and to adopt, promulgate, repeal, and amend rules and regulations consistent with law for the protection of the public health.130 The State Legislature had "delegated to the State Board of Public Health the duty and powers necessary to control and regulate the purity, potability, and wholesomeness of public waters in this state."131
The De Aryan court further found that the entire police power of the state is vested in the legislature, and is only limited by the State Constitution and other applicable statutes.132 Furthermore, even though the enforcement of police power may seem harsh at times, it is an indispensable part of state sovereignty and may not be legally limited unless its use is unreasonable and arbitrarily invoked.133 Accordingly, applying the rational basis test, the De Aryan court concluded that the addition of fluoride to the public water system was a valid exercise of police power as long as it was not unreasonable or an abuse of discretion.134 Although the petitioner taxpayer proffered exhibits, reports, and expert witnesses at the trial, there was no allegation in the petition that the City Council abused its discretion or made an unreasonable decision to endorse fluoridation.135 Therefore, the District Court of Appeal could not consider the evidence.136
A somewhat different challenge against the authority of a city to fluoridate the public water system was made in Wilson v. City of Mountlake Terrace.137 In Wilson, the appellants, representing a class of 300 persons in an unincorporated area adjacent to Mountlake Terrace, objected to the introduction of fluoride into their water by the Alderwood Water District.138 Alderwood was under contract to provide fluoridated water to Mountlake Terrace, and also provided water to the appellants through a common distribution line.139 The appellants argued that a city cannot exercise its police power outside its boundaries, and, therefore, Mountlake Terrace was without authority to impose fluoridation on persons living outside the city.140 The appellants, however, did not claim to be harmed by the fluoridation, and stipulated that fluoridation did not render the water unfit for human consumption according to health department standards.141 The Supreme Court of Washington agreed with the trial court's finding that "the fluoridation of appellant's water is the incidental, although inevitable, result of the city's exercise of its police power ...."142 Applying the rational basis test, the court affirmed the judgment for Mountlake Terrace allowing continued fluoridation because of the finding that appellants were not harmed.143
B. Scope of Police Power Exceeded by the States
In 1954, one year after the De Aryan challenge, residents of Tulsa sought to enjoin enforcement of an ordinance authorizing fluoridation of the city water supply, alleging that it constituted an unwarranted exercise of state police power.144 These plaintiffs, in Dowell v. City of Tulsa, argued that Oklahoma had "never . . . attempt[ed] to regulate or control any disease except those that are 'contagious, infectious, or dangerous'".145 The Dowell court, however, did not believe that the Oklahoma Legislature "intended to restrict its enactment of measures designed to promote the public health and welfare to those designed to prevent the spread of [such] diseases."146 The court found support for its position by noting the many statutes regulating food, lodging, and other subjects "that have no direct connection with or relation to [such] diseases."147 Thus, using the rational basis test, the court upheld the fluoridation statute as a valid exercise of state police power "relating to eugenics and the maintenance of a healthy, normal, and socially sound populace."148
That same year, the appellant in McGurren v. City of Fargo149 challenged the police power of the state, alleging that an implied contract exists between the public water system supplier and the consumer.150 The rationale was that the city furnished and sold water in a proprietary capacity, and since the appellant had performed his contractual requirements by making the necessary service arrangements and paying the city for the water, then the city was mutually obliged to furnish water that was as reasonably pure and wholesome as possible.151 The appellant further argued that the city breached the implied contract by adding fluoride to the water because the water was no longer free from any contamination, rendering the water "unfit for domestic use and unsafe and dangerous to individuals."152 The appellant then argued that this breach endangered the health of the community, thereby exceeding the police power, which is intended to protect the public's health.153 Accordingly, the McGurren court felt that an injunction preventing the addition of fluoride to the public water supply was proper and overruled the appellee's demurrer,154 remanding the case to the district court to allow the City of Fargo answer the complaint.155
C. Constitutional Challenges
The constitutional challenges brought against the fluoridation of public water systems have covered the entire spectrum of colorable arguments. These arguments include First Amendment freedom of religion, Fourteenth Amendment denial of liberty, abridgement of privileges and immunities, and denial of equal protection, and finally, Ninth Amendment invasion of personal privacy.
1. Fourteenth Amendment ChallengesThe Fourteenth Amendment to the United States Constitution provides, in pertinent part, that
no State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the 1aws.156
Challenges to public water system fluoridation statutes typically include allegations of: (1) deprivation of personal liberty; (2) abridgement of one's privileges and immunities; or (3) denial of equal protection of the law.
(a) Deprivation of Personal Liberty
Two years after a federal court in California rendered the decision in De Aryan,157 the seminal case of Kraus v. City of Cleveland158 was decided in Ohio Supreme Court. The plaintiff in Kraus attacked legislation authorizing fluoridation of the public water supply as an infringement of fundamental liberties.159 Urging that every individual has a personal liberty right "to protect his health as he deems best to insure a long and happy life," the plaintiff argued that fluoridation of the city water supply deprives him of this right in violation of the Fourteenth Amendment.160 The Kraus court recognized this personal liberty right, but noted that it is not absolute because it is subject to limits stemming from the police powers of the state.161 The plaintiff argued, however, that individual rights are subordinate to state police powers only when there is an overriding public purpose, such as a present danger, necessity, or emergency, and suggested that no such purpose existed to justify fluoridation of the water supply.162 The Kraus court then examined the scope of the police power under Ohio law and found that if it satisfied the following four prongs, it was a valid exercise of police power: (1) it must be reasonable and necessary to achieve the legislature's objectives; (2) it must not violate the U.S. Constitution; (3) it must not be in direct conflict with any provision of the State Constitution; and (4) it must not be used in an arbitrary and oppressive manner.163
The public health measure at issue in Kraus pertained to the prevention of dental caries by increasing resistance in children to tooth decay, which the court felt was a "serious and widespread disease."164 Accordingly, the Kraus court found that "any reasonable measure designed to decrease or retard the incidence of dental caries is in the interest and welfare of the public," and that this exercise of police power was not arbitrary or oppressive.165 Thus, although the Kraus court did not disagree that fluoridation is an invasion of a person's constitutional right to protect his health as he deems best, it applied the rational basis test and held that this right must yield to police power exercised to prevent caries in Children.166
(b) Abridgment of Privileges and Immunities
In Teeter v. Municipal City of La Porte,167 an action was brought to enjoin fluoridation of the municipal water supply, based on allegations that the local ordinance abridged the Privileges and Immunities Clause168 of the Fourteenth Amendment.169 The appellants argued that fluoridation of the public water system was "an enforced method of taking drugs and giving [the] same to their children . . . [and that] each individual should have the right to determine what to drink and eat without dictation from others ...." 170 The court determined, however, that it was "not necessary to decide the constitutional issues at this stage of the proceeding" and merely indicated that it was not "in a position to hold conclusively as a matter of law [that] fluoridation will not have cumulative toxic effects."171 Thus, the Teeter decision did not advance the legal analysis of constitutional issues raised by forced fluoridation.
Almost ten years after Teeter, plaintiffs in Paduano v. City of New York172 sought to enjoin the proposed fluoridation of the public water system arguing that, among other things, it violated the Privileges and Immunities Clause of the Fourteenth Amendment to the U.S. Constitution as well as Article I, Section 1 of the New York State Constitution.173 The Paduano court held that fluoridation of the water supply "may be the only practical method of insuring the administration of this drug to the very young," and is probably the most efficient and cheapest method of doing so.174 The court also held that "[i]t is not shocking to realize that the State, acting in the interest of children, too young to be sui juris,175 may intervene in the parental area."176 The plaintiffs' motion for an injunction was denied because the Paduano court felt bound by the principles of stare decisis177 to follow other cases, where the Supreme Court has denied certiorari to all fluoridation challenges.178
(c) Denial of Equal Protection of the Laws
It is undisputed even by the proponents of fluoridation that any benefit provided by fluoridation affects only tooth enamel that is still developing in children. Therefore, challenges have been made alleging that fluoridation of public water systems violates the Equal Protection Clause of the Fourteenth Amendment179 because it affects only a limited class, namely, children.180 These challenges have been dismissed because the United States Supreme Court has held that police power may be applied to a reasonable classification, and that just because the class is not all-embracing does not mean the legislation violates the Equal Protection Clause.181 Several courts have held that fluoridation does not affect only a limited class because "[c]hildren of today are adult citizens of tomorrow"182 and "it is apparent that children become adults."183 Thus, the characterization of fluoridation laws as "class legislation" has passed the rational basis test applied by the courts.
2. First Amendment Right to Freedom of Religion
Another constitutional challenge asserted against fluoridation is based upon religious beliefs held by many citizens which forbid them to take medication for the prevention or treatment of any disease. The First Amendment to the United States Constitution provides, in pertinent part, that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof."184 Thus, many cases have been brought, based on the theory that fluoridation violates the First Amendment right to freedom of religion.185
A First Amendment challenge was raised in Kraus v. City of Cleveland,186 where the plaintiff contended that fluoridation of the public water system "compels people to take a form of medication contrary to their religious beliefs" in violation of the First Amendment.187 The Kraus court noted that the United States Supreme Court has held that "freedom of religion has a dual aspect, freedom to believe, and freedom to act exercising such beliefs. The first is an absolute right, [but] the second is not," and therefore may be regulated in order to protect society.188 Accordingly, the Kraus court held that the constitutional guaranty to freedom of religion must yield to regulations imposed "in the interests of the public welfare."189
3. Ninth Amendment Implied Right of Personal Privacy
In addition to the explicit constitutional rights protected by the First and Fourteenth Amendments, the Ninth Amendment provides that "[t]he enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people."190 This amendment was enacted so as to ensure that the government cannot violate fundamental rights of the public merely because those rights were not explicitly protected by the Constitution. Under the auspices of the Ninth Amendment, the City of Brainerd, Minnesota alleged that people have a prerogative to refuse fluoridation which is derived from the implicit constitutional right of privacy.191 While there is no explicit mention of the right of privacy in the Constitution, the United States Supreme Court has held that "the right of privacy protects an individual's right 'to be free from unwarranted governmental intrusion into matters so fundamentally affecting a person,"' such as the decision whether or not to terminate pregnancy.192
The Brainerd court recognized that while the United States Supreme Court has never ruled on the issue, "the right of personal privacy could also extend to protect an individual's decision regarding what he will or will not ingest into his body."193 The Supreme Court, however, has held that "the constitution does not protect an individual 'against all intrusions' but only 'against intrusions which are not justified in the circumstances, or which are made in an improper manner'."194 The Brainerd court found that while forced fluoridation does infringe upon an individual's freedom, such infringement cannot be given substantial weight if there are no significant adverse consequences to the individual.195 If any weight were given to this infringement, the court felt that people could interfere with governmental enactment of similar public health measures, such as chlorinating the water.196 Accordingly, the Brainerd court held "that fluoridation is a justified intrusion into an individual's bodily integrity."197
The most recent reported challenge to fluoridation is the 1994 case Safe Water Association, Inc. v. City of Fond Du Lac.198 In Safe Water, the appellant asserted, inter alia, that the city's adoption of an fluoridation ordinance violated the constitutional right to privacy.199 Plaintiffs had to first overcome the hurdle presented by Froncek v. City of Milwaukee, 200 a 1955 Wisconsin Supreme Court decision upholding fluoridation. In order to dispose of its adverse impact, Safe Water pointed out that the precedential weight of this decision was sufficiently limited by the more recent decisions of the United States Supreme Court in Griswold v. Connecticut201 and Roe v. Wade,202 which drastically enlarged the scope of the right to privacy.203 The Safe Water Court noted that the U.S. Supreme Court recognized the implicit guarantee of "zones of privacy" in Carey v. Population Services, Int'1.,204 but that this right of privacy is narrow and is subject to some limitations.205 The court then granted summary judgment against Safe Water Association, reasoning that it failed to see any relationship between cases concerning the freedom to make reproductive choices and the issue of the right to be free from fluoridated water.206
IV. Analysis
A proper analysis of the statutes authorizing the fluoridation of public water systems must begin with a review of the limitations on state police power. Laws relating to "minimum wages for women and minors, maximum hours for women and minors, . . . control of venereal disease, blood tests for marriage licenses, sterilization, pasteurization of milk, chlorination of water, and vaccination have all been held valid as based on police power exercised in regard to public health."207 However, the United States Supreme Court has never decided whether fluoridation of public water involves constitutional issues, and thus the lower courts must make their own determination if fluoridation is a valid exercise of state police power or a constitutional violation.208
A. Lack of Authority Challenges
The first category of challenges to fluoridation of public water systems involves the lack of authority for states to require fluoridation of public water systems.209 The first reported challenge to fluoridation was De Aryan v. Butler, 210 where the issue was whether the city council of San Diego and the State Board of Health had the authority to require that fluorides be added to the public water supply.211 The District Court of Appeal held that the State Board of Health was delegated the police power "necessary to control and regulate the purity, potability and wholesomeness of public waters in the state."212 Because there was no allegation that the city council of San Diego abused its discretion or acted unreasonably in enacting the fluoridation statute, the De Aryan court correctly concluded that the statute was a valid exercise of police power.213
In the case Wilson v. City of Mountlake Terrace,214 plaintiffs challenged the authority of the city to fluoridate their water, arguing that they lived outside the city limits and, therefore, are not citizens, residents, nor taxpayers of the city.215 The Supreme Court of Washington correctly concluded that the valid exercise of police power may not be challenged by someone experiencing an incidental effect, if such individual does not allege that any harm resulted therefrom.216 The challenges to fluoridation in these two cases did not involve constitutional issues, and, therefore, the rational basis test was properly employed as the basis for judicial review.
B. Scope of Police Power Exceeded Challenges
The second category of legal challenges to fluoridation of public water systems involves allegations that the state exceeded the scope of their police powers.217 The appellant in Dowell v. City of Tulsa218 contended that police power was limited to the regulation of contagious, infectious, or dangerous diseases, but the court felt this distinction was immaterial, ridiculous, and of no consequence to the promotion of public health.219 In the case McGurren v. City of Fargo, 220 the appellant convinced the court that he had a breach of contract issue, which was then remanded to the lower court for resolution.221 The Dowell court properly used the rational basis test to find that the state did not exceed the scope of its police power, because the appellant failed to sufficiently identify a fundamental constitutional right which was infringed. The McGurren court never reached the constitutional issues raised, and thus did not further the constitutional analysis of fluoridation laws.
C. Constitutional Challenges
The third category of legal challenges to fluoridation of public water systems involves allegations that the state deprived an individual of their personal liberty, abridged their privileges and immunities, or denied them equal protection of the law in contravention of the Fourteenth Amendment to the United States Constitution.222
1. Deprivation of Personal Liberty Challenges
The problem in making a challenge that fluoridation of public water systems deprives a person of personal liberty is that this constitutional right is not absolute; the Constitution provides that no state may deprive a person of liberty without due process of law.223 "Liberty" may be subdivided "into three headings involving governmental restraints on (1) physical freedom, (2) the exercise of fundamental constitutional rights, and (3) other forms of freedom of choice or action."224 The liberty guaranteed and protected by the Fourteenth Amendment includes the freedom to marry, establish a home, bring up children, live and work where one chooses, get a job, acquire useful knowledge, use and enjoy one's faculties, freedom from unauthorized physical restraint, and those privileges "essential to the orderly pursuit of happiness by free people."225
A state may enact legislation and deprive citizens of that state of any of these rights, but the citizens must first be afforded due process of law.226 Due process is a course of legal proceedings according to the rules and principles which have been established in our legal system for the protection and enforcement of private rights.227 "Substantive" due process provides protection from arbitrary and unreasonable actions, while "procedural" due process requires that a party whose rights are to be affected be given notice and an opportunity to be heard before a court or other appropriate decision-making body.228
The appellant in Kraus v. City of Cleveland229 alleged that he was deprived of his liberty to protect his health as he deems best, but did not claim that he was denied due process.230 The Kraus trial court had applied the rational basis test to the fluoridation statute and found it to be a valid exercise of police power, which was affirmed by the Supreme Court of Ohio.231 The problem in this and every other case is that the rational basis test does not apply if the statute being analyzed interferes with a fundamental right.232 This is where the ambiguity arises, because the "law" is constantly changing, and what is unconstitutional today may be legal tomorrow.233 Therefore, modern courts should reanalyze the limitations on personal liberty in light of recent Supreme Court cases. When it is finally decided that fluoridation of the public water systems impinges on a fundamental right, the rational basis test will be inappropriate, and strict judicial scrutiny by the courts will be required.
2. Abridgement of Privileges and Immunities Challenges
The problem in making a challenge that fluoridation of public water systems abridges a person's privileges and immunities is that the purpose of this clause is to protect "those rights peculiar to being a citizen of the federal government; it does not protect those rights which relate only to state citizenship."234 The privileges and immunities challenges made in Teeter v. Municipal City of La Porte235 and Paduano v. City of New York236 have nothing to do with citizenship privileges in different states and thus are unfounded in the Constitution.237 Accordingly, these cases were properly decided using the rational basis test of judicial review.
3. Denial of Equal Protection of the Laws Challenges
The last Fourteenth Amendment challenge to statutes authorizing the fluoridation of public water systems is that they violate equal protection of the laws.238 In Chapman v. City of Shreveport,239 the appellees argued that it was unreasonable to fluoridate the water when it affected only a limited class.240 This argument, however, goes towards proving that fluoridation statutes are not narrowly tailored, not that they have been denied equal protection of the laws. Equal protection of the laws requires that individuals be treated in a similar manner.241 No claim was made in Chapman that the appellee was not receiving the same protection being provided to other persons in similar circumstances; instead, he was trying to remove himself from the prophylactic medication being provided to children through fluoridated water.242
The Supreme Court of Louisiana stated that the exercise of police power is not objectionable solely because it does not apply to all classes, and held that the legislature is allowed to subject adults to fluoridation because the statute was not arbitrary, oppressive, or unreasonable.243 This holding unduly expands the purpose of police power, which is supposed to promote the general welfare of the majority of the public. American households are composed mainly of adults, not children, and thus, fluoridating public water systems is an overbroad use of police power which can cause adverse health effects for the majority of the public.244
There are many reasonable alternatives available to parents who want their children to receive fluoride treatment, such as topical gels, mouth rinses, children's toothpaste, fluoride tablets, and drops.245 A study found that "fluoride administered in tablet form or in vitamin preparations was more than twice as effective as fluoridated water in preventing cavities."246 Children ages 7 to 12 had no tooth decay in 54% of those who took fluoride tablets or drops since infancy, while only 23.9% of adults with lifetime exposure to fluoridated water were cavity-free.247 An additional argument supporting fluoride supplementation from sources other than public water systems is that fluoride tablets or drops can be administered in exact doses, but the amount of fluoride ingested from drinking tap water cannot be controlled.248 These tablets or drops can then be discontinued after the permanent teeth have finished developing around age 10-12, or even sooner if deleterious side effects occur.249
4. Freedom of Religion Challenges
In addition to the Fourteenth Amendment challenges, many plaintiffs alleged that the state had violated their First Amendment right to freedom of religion.250 The appellant in Kraus v. City of Cleveland251 claimed that fluoridation of the water supply compels people to take a form of medication contrary to their religious beliefs in contravention of the First Amendment to the U.S. Constitution and the State Constitution.252 The United States Supreme Court has ruled on similar challenges, and has held that the freedom to believe is absolute and is a fundamental right, but the freedom to act according to such beliefs is not fundamental and may be regulated under police powers.253
The Kraus court then tried to distinguish fluoridation from other infringements on freedom of religion.254 The court recognized that although the City of Cleveland is the sole supplier of public drinking water within that city, there is no absolute duty on the part of the city to supply water.255 Furthermore, courts have held that citizens opposed to drinking fluoridated water are free to buy non-fluoridated water because there is no direct compulsion to drink tap water.256 The Kraus court recognized that obtaining non-fluoridated water may pose a problem of inconvenience for some and possibly of economics for others, but felt it was not a wholly impossible situation.257
The argument that there is no compulsion to drink fluoridated water is without merit. Public water systems were established to serve the public.258 Since the majority of the public are adults, then fluoridating tap water to provide a drug to a minority of the public (children) defeats the whole purpose of the public water system. Besides the inconvenience and expense of having to buy bottled water, it is virtually impossible to escape eating processed foods that have been prepared using fluoridated water. Therefore, there is a compulsion to ingest fluoridated water, whether it comes from the faucet or from the foods we eat. Although the Kraus court felt there was no compulsion to drink fluoridated tap water, the ease at which it reached that conclusion suggests the worthlessness of the achievement. Despite the erroneous conclusion by the Kraus court, it correctly applied the rational basis test to the infringement of religion challenge, because the Supreme Court has not recognized the exercise of religion as an absolute constitutional right.259
5. Right of Privacy Challenges
The very last category of legal challenges to fluoridation of public water systems involves allegations that the state deprived someone of their implied Ninth Amendment constitutional right of personal privacy to be free from unwanted government intrusions.260 The Minnesota Supreme Court recognized this implicit constitutional right in Minnesota State Board of Health v. City of Brainerd,261 but felt that it only protected against intrusions that were unjustified or made improperly.262 The Brainerd court felt that if much weight was given to the right of privacy argument, then people could start refusing to let the government make similar intrusions.263 Other courts have acknowledged the "zone of privacy" espoused by the U.S. Supreme Court in Carey v. Population Services, Int'1.,264 but have held that this zone is narrow and subject to limitations.265
Some states, however, have determined that fluoridation of public water systems falls within this zone of privacy. The trial court in Chapman v. City of Shreveport266 concluded that fluoridation of the city water supply was not reasonably related to the public health, and that tooth decay is not a matter of public health.267 Furthermore, it held that the choice to ingest fluoride is strictly "within the realm of private dental health and hygiene," and that every person should be free to choose his medical treatment for himself and his family.268
Along these same lines, the dissent in Minnesota State Board of Health v. City of Brainerd269 realized that although the majority had used a balancing test to weigh the state's intrusion into the citizen's right of privacy, they failed to look at other alternative means that minimized intrusion.270 Given that Minnesota's purpose was to make publicly-funded fluoride treatment readily available, the dissent felt that the city could have been compelled to provide fluorine tablets or dental applications to whomever wanted treatment, without infringing on the right of privacy of the majority.271 Justice Yetka concluded by noting that there was not a compelling state interest to fluoridate the water, especially since it could possibly be carcinogenic, and that reasonable alternatives existed, which tipped the balance in favor of an individual's rights.272
The dissent in Kaul v. City of Chehalis273 recognized that measures directly affecting the bodily integrity of a person represent the most penetrating exercise of police power.274 Only the emergency of a present danger justifies quarantine, isolation, or compulsory treatment, and it is doubtful whether compulsory vaccination can be made without such danger.275 Justice Hill, in his dissent, pointed out that any proposed health regulation must not impair essential rights and principles, and anyone who wants or needs fluorine can get a prescription for topical application, or ingest it by other ways.276 Additionally, he noted that the United States Supreme Court has held that health regulations must not restrain personal liberty "under conditions essential to the equal enjoyment of the same right by others" or unless there is "pressure of great dangers" to the public's safety.277
Justice Hill reiterated the well known fact that "[w]hile dental caries may be termed a 'disease' which is prevalent in the teeth of almost everyone, it is not contagious or communicable in any way."278 In addition, "[d]ental caries in no way endangers the public health in the sense that its existence in the teeth of one individual might adversely affect the personal health of any other individual."279 Furthermore, Justice Hill felt that allowing the state to fluoridate public water systems would open the door to compulsory mass medication or preventative treatment for any disease without regard to a person's right to decide such matters for himself.280 Justice Hill concluded that the "prevention of dental caries by compulsory treatment of the teeth does not fall within the scope of protection of the public dental health for which the police power may be invoked."281 He believed that education and persuasion, not compulsion, should be the government's goal if fluorine is actually the key to dental health.282
D. Supreme Court Stance on Unwanted Medical Treatment
In Cruzan v. Director, Missouri Department of Health,283 the United States Supreme Court stated that although many state courts have analyzed the right to refuse medical treatment under the implied constitutional right of privacy, it "is more properly analyzed in terms of a Fourteenth Amendment liberty interest."284 In Cruzan, the Supreme Court acknowledged that "[t]he principle that a competent person has a constitutionally protected liberty interest in refusing unwanted medical treatment may be inferred from our prior decisions."285 Additionally, the Supreme Court assumed that the Constitution would grant a person "a constitutionally protected right to refuse lifesaving hydration and nutrition."286 In a prior case, the Supreme Court held that "[t]he forcible injection of medication into a nonconsenting person's body represents a substantial interference with that person's liberty."287 However, the court also recognized that while a person has a liberty interest under the Fourteenth Amendment Due Process Clause, whether the person's "constitutional rights have been violated must be determined by balancing his liberty interests against the relevant state interests."288 This "relevant" state interest, also referred to as a "compelling" state interest,289 is one which the state is forced or obliged to protect.290 While all states have a compelling interest to prevent contagious diseases, such as the spread of smallpox in Jacobson v. Massachusetts, 291 tooth decay is not contagious, poses no risk of an outbreak, and thus is not a compelling interest such as would require state intervention. Accordingly, courts should apply a strict scrutiny standard of review when balancing a substantial liberty interest against fluoridation, which is, in effect, merely a state-mandated prophylactic measure for a noncontagious disease. A strict scrutiny standard requires that a state have a compelling interest to enact legislation, and that such legislation be narrowly tailored to achieve its purpose so as not to infringe on personal liberty interests protected by the Constitution.292
There is clearly no right or compelling interest for the federal government to mandate fluoridation of drinking water because it is known that fluoride is a contaminant which may have an adverse affect on the health of persons.293 If states were bound by the Safe Water Drinking Act, then they would be prohibited from requiring fluoridation of the public water systems, despite their police power. This state police power is supposed to be used to promote the general health and welfare of the public, and should not be used as authority to purposely add contaminants into public drinking water. While reasonable minds may differ about whether the state's interest in health encompasses non-contagious diseases and whether this interest is compelling, fluoridation of public water systems does not pass constitutional muster because it fails the second prong of the strict scrutiny test: it is not narrowly tailored to achieve the legislature's purpose, and reasonable alternatives exist.
V. Conclusion
It is incumbent upon the United States Supreme Court to grant certiorari to the next fluoridation challenge brought based upon a due process violation of an individual's liberty interest. Whereas the Supreme Court has yet to resolve the issue of whether fluoridation invades a constitutionally protected interest when the state mandates the ingestion of a prophylactic drug to prevent a noncontagious disease, the Court has held, however, that a state may exercise its police power to protect the public from the spread of contagious disease. This distinction between contagious and noncontagious disease is critical because it determines the extent of the state interest when balancing the right of an individual to be free from compulsory medication against the state interest in attempting to prevent tooth decay by fluoridating public water systems.
The holding in Washington v. Harper294 reflects the modern Supreme Court position, whereby "[t]he forcible injection of medication into a nonconsenting person's body represents a substantial interference with that person's liberty."295 However, this holding is qualified by the caveat that whether this constitutionally protected liberty interest has been violated "must be determined by balancing that liberty interest against the relevant state interests."296 The balancing is accomplished by subjecting fluoridation statutes to a strict scrutiny review in order to determine if they pass constitutional muster.
Because there is no compelling state interest to mandate prophylactic drugs for a noncontagious disease, the means of accomplishing the legislature's goals is not narrowly tailored, and reasonable alternatives exist, fluoridation statutes will fail the strict scrutiny test. Pursuant to the holdings in Harper and Cruzan, it is reasonably certain that fluoridation of public water systems will eventually be deemed a substantial invasion of personal liberty in violation of the Constitution of the United States of America.
Fluoridating public water in an attempt to target children whose permanent teeth are still developing is like using a shotgun to shoot an apple off someone's head; sure, you hit the apple, but the side effects are undesirable.
