Violations: the EPA’s Safe Drinking Water Information System, health-based violations 2021 to 2025. PFAS: the EPA’s fifth Unregulated Contaminant Monitoring Rule samples, against the EPA’s reference of 4 nanograms a litre, shown for PFOA and PFOS only. Compliance is judged on running annual averages, not the single highest result shown here. Lead: each system’s service-line inventory as filed with the state; galvanized lines that were ever downstream of lead must be replaced too. A violation can be resolved; each system’s town pages show when. More visual stories →
