Monitoring Violation: 8 violations, Apr 2024 to Jan 2025. 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: 3 violations, Apr 2024 to May 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: Chlorine (MRDL).

Maximum Contaminant Level Violation, health-based: 5 violations, Apr 2025 to Jun 2026. A sample exceeded the maximum contaminant level EPA allows in drinking water.

What the rule requires: Arsenic is a naturally occurring metalloid found in bedrock and soil. It dissolves into groundwater from natural deposits and can also come from mining, smelting and past pesticide use. EPA lowered the MCL from 50 ppb to 10 ppb in 2001.

Health effects: Long-term arsenic exposure increases risk of bladder, lung, and skin cancers. It is also associated with cardiovascular disease, type 2 diabetes, and developmental effects in children. Arsenic is classified as a Group A human carcinogen by the EPA. Limit: 0.010 mg/L (10 ppb), set in 2001 and enforceable since 2006; the previous MCL was 0.050 mg/L (50 ppb)

Maximum Contaminant Level Violation, health-based: 4 violations, Jul 2025 to Jun 2026. A sample exceeded the maximum contaminant level EPA allows in drinking water.

Contaminant on the record: Fluoride.

Fluoride, health effects: Above 2 mg/L: dental fluorosis (mottling/pitting of tooth enamel) in children under 8. Above 4 mg/L: skeletal fluorosis (joint pain, increased bone density) after decades of exposure. Limit: 4 mg/L primary MCL; 2 mg/L secondary MCL (cosmetic)

Maximum Contaminant Level Violation, health-based: 7 violations, Oct 2024 to Jun 2026. A sample exceeded the maximum contaminant level EPA allows in drinking water.

What the rule requires: 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)

Monitoring and Reporting: 2 violations, Jan 2025 to Apr 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.

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.

Other Violation: 6 violations, May 2025 to Sep 2025. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.

Contaminant on the record: Public Notification Rule.
