About these guides
Drinking-water regulations decide what your utility tests for, how often samples are pulled, which results trigger public notice, and what ends up in the annual report on your doorstep. For a water system, they are the compliance floor. For a resident, they are the reason most of what you know about your tap water is knowable in the first place. These guides walk through the federal rules in plain language so operators, board members, and ratepayers can read the same page and reach the same conclusions.
We cover four families of federal drinking-water rules. The Consumer Confidence Report (CCR) Rule governs the annual water quality report utilities must deliver to customers. The Lead and Copper Rule (LCR), together with its 2021 Revisions (LCRR) and 2024 Improvements (LCRI), sets sampling, service-line inventory, and replacement requirements. The 2024 PFAS National Primary Drinking Water Regulation (NPDWR) sets enforceable maximum contaminant levels for six per- and polyfluoroalkyl substances. And the broader NPDWR framework is the umbrella EPA uses to set standards under the Safe Drinking Water Act.
These pages explain the rules, not the contaminants themselves. If you are looking for health effects, exposure routes, or how a specific contaminant behaves in treatment, see our contaminant-specific health data and the EPA drinking-water standards overview. If you have a CCR in hand and want to decode it line by line, start with how to read your CCR.
The revised CCR Rule is an active compliance deadline for every community water system in the country. EPA finalized the revision in 2024 with a compliance date of January 1, 2027. The first revised CCRs must reach customers by July 1, 2027, and systems serving more than 10,000 people must distribute reports twice a year rather than annually. Utilities still drafting templates, rebuilding distribution lists, or retraining staff on the new health-effects language should treat the 2027 deadline as the planning anchor, not the finish line.
