Lead and Copper Rule Revisions (LCRR)
The 2021 LCRR updated the 1991 LCR with mandatory lead service line inventories and replacement planning, a new 'trigger level' at 10 ppb requiring…
What it means: The 2021 LCRR updated the 1991 LCR with mandatory lead service line inventories and replacement planning, a new 'trigger level' at 10 ppb requiring optimization, and strengthened public education. The 2024 Lead and Copper Rule Improvements (LCRI) further requires replacing all lead service lines within 10 years.
Health effects: Same as Lead and Copper Rule (5000). Violations typically reflect failure to complete the required lead service line inventory or submit a required replacement plan. Lead service lines are the primary source of lead at the tap in many older systems.
Limit: Lead action level: 15 ppb (trigger level: 10 ppb); copper action level: 1.3 mg/L

Nitrate (NO₃) is the most common chemical contaminant in US groundwater, entering from fertilizers, septic systems, and animal waste.
What it means: Nitrate (NO₃) is the most common chemical contaminant in US groundwater, entering from fertilizers, septic systems, and animal waste. It is odorless and tasteless — the only way to know if it's present is to test.
Health effects: Methemoglobinemia in infants under 6 months: gut bacteria convert nitrate to nitrite, which blocks oxygen transport in blood. Pregnant women should also take precautions. Chronic adult exposure at elevated levels may increase cancer risk.
Limit: 10 mg/L as nitrogen (NO₃-N)
About this contaminantAbout this data
EPA counts the rules a system was in violation of, not the individual violations; one rule can carry several in the same period. Unresolved means still in violation at EPA's latest data refresh. Measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.
Service area from EPA's Public Water System Service Area Boundaries dataset: location confidence State Sourced. The system's location is the centre of the service area EPA publishes for the system.

The California records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
