Consumer Confidence Reports by State

Every community water system in the United States produces its Consumer Confidence Report under the same federal floor — 40 CFR Part 141 Subpart O (§§ 141.151–141.156) — but the state primacy agency layered on top of that floor often sets stricter deadlines, additional disclosure fields, mandatory templates, or lower language thresholds than federal law requires. This page indexes both layers: the federal requirements that apply everywhere, and the state-specific coverage we publish in depth.

For a full explanation of what a CCR is and who must write one, see the CCR Resources overview.

How federal and state CCR rules interact

Federal CCR rules come from the Safe Drinking Water Act, as amended by the 1996 SDWA amendments (42 U.S.C. § 300g-3(c)(4)) and the America's Water Infrastructure Act of 2018. Those statutes directed EPA to publish and periodically revise the Consumer Confidence Report Rule, which now lives at 40 CFR §§ 141.151–141.156. The May 2024 revisions to that rule — published at 89 FR 46013 — added a mandatory summary section (§ 141.156), codified electronic delivery as an option, and triggered biannual reporting for systems serving 10,000 or more persons, with second reports due December 31.

Every state that has obtained primacy from EPA must enforce rules that are at least as stringent as the federal floor. Most go further. California's CCR requirements appear in Title 22 of the California Code of Regulations and Health and Safety Code § 116470; they set lower language thresholds than the federal standard and require submission through the State Water Resources Control Board's electronic Annual Report (eAR) portal. Texas administers its CCR program under 30 TAC § 290 through the Texas Commission on Environmental Quality, which sets its own certification deadline of May 1. Florida, New York, and Illinois each run parallel programs with distinct submission portals, templates, and supplemental disclosure fields.

The practical implication for utility staff: the federal CFR tells you the minimum; your primacy agency tells you what you actually have to file, where to file it, and by when. If there is any conflict between what you read here and guidance from your primacy agency, follow your primacy agency.

Wyoming and the District of Columbia do not have delegated primacy — EPA administers their programs directly.

States we cover in depth

We publish detailed, citation-grounded guidance for five states at launch: California CCR requirements, Texas CCR requirements, Florida CCR requirements, New York CCR requirements, and Illinois CCR requirements. Each of those pages covers the state's primacy agency contacts and portals, state-specific deadlines, template and formatting requirements, language threshold rules, and any supplemental disclosure fields that go beyond the federal floor. Together these five states account for a significant share of community water systems nationwide.

For all other states, the table below identifies the primacy agency and links out when we have published additional guidance.

All 50 states — primacy agency at a glance

EPA maintains the canonical list of primacy agencies at epa.gov/DWdata/primacy-agency-drinking-water-data. The agencies below are drawn from that source.

Tribal nations: many federally recognized tribes administer their own drinking water programs under EPA primacy delegation. The Navajo Nation Environmental Protection Agency, for example, holds primacy for Navajo Nation public water systems. For tribal CCR obligations, contact the relevant tribal environmental agency or EPA's Tribal Drinking Water program at epa.gov/tribaldrinkingwater.

How to find your state's specific CCR rule

Search "{your state} consumer confidence report rule" or navigate directly to your primacy agency's drinking water program page. Most agencies publish CCR guidance, certification forms, and in many cases a mandatory or recommended CCR template.

The canonical starting point is EPA's primacy agency data page at epa.gov/DWdata/primacy-agency-drinking-water-data, which lists each agency with a direct link to its drinking water program and, where available, its publicly accessible compliance database. If you are unsure which agency to contact, that page is the authoritative source.

For questions about federal requirements — delivery methods, population-threshold cliffs, mandatory disclosure language, or PFAS monitoring obligations — the federal CCR rule at 40 CFR §§ 141.151–141.156 is the primary reference.
