EPA vs. FDA: How Tap Water and Bottled Water Are Regulated

Who this page is for

Anyone who's wondered why bottled and tap water seem to follow different rules

Tap water and bottled water are both closely regulated in the United States — but by two different federal agencies, under two different laws, with two different sets of requirements. Neither is automatically "safer" than the other; they're just held to their standards in different ways. This page walks through who regulates what, and explains the specific regulation behind the annual water quality report your provider is required to send you.

Tap water

How the EPA regulates public tap water

Public tap water — delivered by a community water system, whether a municipal authority or an investor-owned utility like a large regional water utility — is regulated by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act (SDWA). The EPA sets National Primary Drinking Water Regulations, which establish legally enforceable Maximum Contaminant Levels (MCLs) for more than 90 specific contaminants — each MCL reflects the level that protects public health while remaining achievable with the best available treatment technology.

Public water systems must follow EPA-set testing schedules and methods, report their monitoring results to the state and EPA, and — critically for homeowners — deliver an annual Consumer Confidence Report (CCR) to every customer, covered in detail below. States can enforce their own standards too, as long as they're at least as strict as EPA's national requirements; in New York, that's the job of the New York State Department of Health (NYSDOH).

Full detail on this framework is available directly from EPA: EPA Drinking Water Regulations.

Bottled water

How the FDA regulates bottled water

Bottled water is legally classified as a packaged food product, which puts it under the jurisdiction of the U.S. Food and Drug Administration (FDA) rather than the EPA. The FDA regulates it under the Federal Food, Drug, and Cosmetic Act (FDCA), through three main types of rules:

• Standard of identity regulations, which define what can legally be labeled as "spring water," "purified water," "mineral water," and other bottled water categories
• Standard of quality regulations, which set maximum allowable levels of chemical, physical, microbial, and radiological contaminants — by law, these must be no less protective of public health than the EPA's equivalent tap water standards
• Current Good Manufacturing Practice (CGMP) regulations, which require bottled water to be produced and bottled under sanitary conditions

Bottled water processors are generally required to register with the FDA as food facilities and comply with the FDA Food Safety Modernization Act's risk-based preventive controls, and their plants are subject to inspection under FDA's general food safety program (with some inspections performed by states under contract). For the full consumer explanation, see the FDA's own guidance: FDA: Bottled Water Everywhere: Keeping It Safe.

The key practical difference

Same underlying safety bar, different transparency requirements

The two systems are built to hold both products to a comparable underlying safety bar — FDA's bottled water contaminant limits are legally required to track EPA's tap water limits. Where they diverge most for an everyday consumer is transparency: a community water system must test frequently, report results to regulators, and mail or otherwise deliver a plain-language annual report directly to every customer. Bottled water companies must meet the standards and are subject to inspection, but there is no equivalent legal requirement to proactively publish a report of test results to consumers the way a CCR does for tap water.

In practice, that means it's often easier to find detailed, dated water quality information about your municipal tap water than about a specific bottled water brand.

The annual report requirement

Why your provider is required to send you a report every year

The Consumer Confidence Report requirement comes directly from the EPA's Safe Drinking Water Act regulations: every community water system — a public water system that serves the same population year-round — must prepare and deliver a CCR to its customers annually, typically by July 1, covering the previous calendar year's data. Systems serving 100,000 people or more must also post their current report publicly online. This isn't optional or provider-specific; it applies uniformly across every community water system in the country, whether it's a small borough authority or a large investor-owned utility.

a large regional water utility is a useful concrete example simply because it's one of the largest providers in our coverage area: like every other community water system, Aqua is legally required to prepare a CCR for each of its service divisions and make it available to customers, which it does through its own water quality reports page. The same requirement applies identically to New York City Department of Environmental Protection, every municipal authority, and every other provider covered on this site — see your county guide for links to reports from providers serving your specific area.

Common mistakes

Mistakes to avoid

• Assuming bottled water is automatically held to a higher safety standard than tap water — the underlying contaminant limits are designed to be comparable
• Expecting a bottled water brand to publish an annual report the way your water utility does — there's no equivalent legal requirement for it to do so
• Confusing "no CCR available" with "not regulated" — if you're on a private well, you're simply outside the community water system framework entirely, not exempt from water quality concerns
• Not checking your own CCR because you assume your provider is too small to be required to send one — the requirement applies regardless of system size

FAQ

Frequently asked questions

Is bottled water more regulated than tap water?

No — it's differently regulated, not more strictly regulated. Tap water from a public water system is regulated by the EPA under the Safe Drinking Water Act, which sets enforceable limits (MCLs) for over 90 contaminants and requires frequent monitoring, state reporting, and an annual public Consumer Confidence Report. Bottled water is regulated by the FDA as a packaged food product under the Federal Food, Drug, and Cosmetic Act, and FDA's bottled water quality standards are required to be no less protective of public health than EPA's tap water standards — but bottled water companies are not required to publish an annual public report to consumers the way community water systems are.

Who do I contact if I have a question about my tap water specifically?

Your local water provider is the right first contact for questions about your specific water. See our Home Water Guides for how to identify your provider and find your Consumer Confidence Report.

Does every water provider have to send me a report every year?

Per the Safe Drinking Water Act (EPA's Consumer Confidence Report Rule): yes — every community water system (a public water system serving the same people year-round, which includes virtually all municipal and investor-owned utilities) is legally required to deliver a Consumer Confidence Report to its customers annually, typically by July 1 each year.
