Monitoring Violation: 1 violation, Dec 2025 to Feb 2026. The system did not complete required monitoring. This does not show that a contaminant was found.

What the rule requires: The 2013 RTCR (effective 2016) replaced the original TCR. It triggers automatic E. coli testing whenever total coliform is found. A single E. coli-positive sample is an acute MCL violation. It also requires systems exceeding 5% total coliform-positive samples to conduct a formal assessment and correct any deficiencies, helping prevent contamination before it escalates.

Monitoring and Reporting: 4 violations, Oct 2025 to Mar 2026. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

Contaminant on the record: Chlorine (MRDL).

Maximum Contaminant Level Violation, health-based: 9 violations, Jan 2024 to Jun 2026. A sample exceeded the maximum contaminant level EPA allows in drinking water.

Monitoring and Reporting: 4 violations, Feb 2024 to Aug 2025. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

Contaminants on the record: Total Haloacetic Acids (HAA5), TTHM (Total Trihalomethanes).

Total Haloacetic Acids (HAA5), health effects: Dichloroacetic acid is a probable human carcinogen (Group B2). Long-term exposure to trichloroacetic acid may also increase cancer risk. Animal studies show liver, kidney, and reproductive effects at high doses. Limit: 0.060 mg/L (60 ppb) locational running annual average (LRAA)

TTHM (Total Trihalomethanes), health effects: Long-term exposure is associated with increased bladder cancer risk. Some studies link high TTHM exposure to adverse reproductive outcomes. Bromodichloromethane is classified as a possible human carcinogen. Limit: 0.080 mg/L (80 ppb) locational running annual average (LRAA)

Monitoring and Reporting: 1 violation, Oct 2021 to Aug 2023. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

What the rule requires: The 1991 LCR uses action levels rather than MCLs: if the 90th percentile of high-risk tap samples exceeds 15 ppb lead or 1.3 mg/L copper, the system must take escalating corrective actions. Violations typically indicate failure to maintain adequate corrosion control — the treatment that keeps lead from leaching out of pipes, solder, and fixtures.

Treatment Technique Violation, health-based: 1 violation, Oct 2024 to Mar 2026. The system did not carry out a required treatment process or corrective action.

Reporting Violation: 1 violation, Oct 2024 to Mar 2026. The system did not report required information on time.

What the rule requires: 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
