Treatment Technique Violation, health-based: 1 violation, Aug 2023 to Aug 2023. The system did not carry out a required treatment process or corrective action.

Monitoring and Reporting: 1 violation, Jul 2025 to Oct 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.

Contaminant on the record: Interim Enhanced Surface Water Treatment Rule.

Interim Enhanced Surface Water Treatment Rule, health effects: Violations indicate failure to meet treatment technique requirements that reduce exposure to Cryptosporidium, Giardia, and other microbial pathogens. Cryptosporidium poses the greatest risk to immunocompromised individuals, infants, and the elderly, and can cause severe or fatal illness in vulnerable populations. Limit: Treatment technique — no numeric MCL; compliance means meeting turbidity limits (0.3 NTU in 95% of monthly samples) and Cryptosporidium removal benchmarks

Treatment Technique Violation, health-based: 3 violations, Oct 2023 to Jun 2024. The system did not carry out a required treatment process or corrective action.

Monitoring and Reporting: 4 violations, Jan 2024 to Oct 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: Chlorine (MRDL), Chlorine dioxide, Carbon, Total.

Chlorine (MRDL), health effects: Acute high-dose exposure to chlorinated water can cause eye and nose irritation, stomach discomfort, and nausea. Chronic exposure above the MRDL is primarily a concern because elevated chlorine accelerates formation of trihalomethanes and haloacetic acids, which are associated with increased cancer risk over time. Limit: MRDL: 4.0 mg/L as an annual average

Maximum Contaminant Level Violation, health-based: 16 violations, Jul 2023 to Jun 2025. A sample exceeded the maximum contaminant level EPA allows in drinking water.

Monitoring and Reporting: 5 violations, Apr 2023 to Jun 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: TTHM (Total Trihalomethanes).

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 2024 to Jul 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.

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.
