Since Oct. 23, 2023, EPA records health-based violations of: Long Term 2 Enhanced Surface Water Treatment Rule. 1 is still open in EPA's record (no end date and no return to compliance), the oldest since Feb. 1, 2017. EPA marks the system as currently having a health-based violation. EPA's detailed report for this system.

Lead and copper: EPA's sample results
Lead, 90th percentile of the samples in the sampling period Jan. 1, 2024 to Dec. 31, 2024, first reported Feb. 10, 2025: 10 ppb (.01 mg/L), not above EPA's action level of 15 ppb.
Exceedances of these action levels are not violations, but trigger other requirements to limit exposure to lead and copper in drinking water. The 90th percentile is the value that 90% of the sampled taps were at or below; EPA lists a result under its whole sampling period, which can end after the day the result was first reported; the action level is not a health standard. Values as EPA reports them (mg/L), shown in ppb for lead; a value marked "not plausible" (below zero, or above 1 mg/L lead or 100 mg/L copper) is listed as EPA has it but is probably a unit or entry error in EPA's file, and is not compared with an action level.| Sampling period ended | Lead (90th pct.) | Copper (90th pct.) |

PFAS (“forever chemicals”): EPA's tests, 2023–2025
No PFAS result at or above EPA's reporting levels in the UCMR 5 file of Oct. 15, 2026.
One-time EPA testing, not a compliance test: a result at or above a limit is not a violation.How EPA tested
UCMR 5 is EPA's one-time testing of 29 PFAS and lithium, to learn where they occur; it is not a compliance test. A result at or above a limit is not a violation: under the 2024 rule a system is judged on the running annual average at each entry point from 2029 (EPA proposed in May 2026 to let systems ask for two more years, to 2031, for PFOA and PFOS; not final). Labs report a result only at or above EPA's minimum reporting level (4.0 ppt for PFOA and PFOS); a lower amount is reported as not found.Source: EPA, UCMR 5 occurrence data, tests from Oct. 25, 2023 to Jan. 2, 2025.

Health-based violations: Violations of maximum contaminant levels (MCLs) or maximum residual disinfectant levels (MRDLs), which specify the highest concentrations of contaminants or disinfectants, respectively, allowed in drinking water; or of treatment technique (TT) rules, which specify required processes intended to reduce the amounts of contaminants in drinking water. MCLs, MRDLs, and treatment technique rules are all health-based drinking water standards.
Monitoring and reporting violations: Failure to conduct regular monitoring of drinking water quality, as required by SDWA, or to submit monitoring results in a timely fashion to the primacy agency.
Public notice violations: Violations of the public notification requirements of SDWA, which require systems to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
Other violations: Violations of other requirements of SDWA, such as issuing annual consumer confidence reports or maintaining required records.
Enforcement priority: 'Yes' indicates a public water system with unresolved serious, multiple, and/or continuing violations that is designated as a priority candidate for formal enforcement, as directed by EPA's Drinking Water Enforcement Response Policy.
Lead and copper action levels: Exceedances of these action levels are not violations, but trigger other requirements to limit exposure to lead and copper in drinking water.
Has new violations: Violations that have been reported to SDWA since end of the last official quarter. These violations are considered draft and do not reflect the official compliance status for the facility.
Sanitary survey: A sanitary survey is an on-site review of a system's water source, treatment, distribution system, storage, pumps, monitoring and reporting, management and operation, and operator compliance, intended to point out sanitary deficiencies and assess the system's capability to supply safe drinking water.
Enforcement actions: Formal enforcement actions compel a PWS to take specific actions by specific dates to return to compliance. Informal enforcement actions do not specify actions and deadlines for returning to compliance.

From EPA's Safe Drinking Water Information System (SDWIS), through EPA ECHO's drinking water system download. Health-based violations from EPA Envirofacts, downloaded Nov. 2, 2026. EPA's file dated Oct. 23, 2026. EPA: “All compliance and enforcement data displayed on ECHO are current as of the last official quarterly refresh of the source data system, SDWIS, which may lag by three to six months.” These are records of violations, not a test of your tap water today: your water system's annual Consumer Confidence Report has its test results.
