Maximum Contaminant Level ViolationMonitoring and Reporting Health-based20 violations, Jul 2023 to Mar 2026 · 3 contaminants · 17 measured values
Maximum Contaminant Level Violation, health-based: 17 violations, Jul 2023 to Mar 2026. A sample exceeded the maximum contaminant level EPA allows in drinking water.
Monitoring and Reporting: 3 violations, Jan 2024 to Mar 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: Gross Alpha, Excl. Radon and U, Combined Uranium, Combined Radium (-226 and -228).
Gross Alpha, Excl. Radon and U, health effects: Alpha-emitting radionuclides accumulate in bone and soft tissue, delivering sustained internal radiation doses that increase lifetime cancer risk. There is no established safe threshold for ionizing radiation. Individual contributors such as radium-226 and polonium-210 have their own MCLs; gross alpha serves as a cost-effective screening tool that triggers more specific radionuclide analysis when exceeded. Limit: 15 pCi/L (excluding radon and uranium)
Combined Uranium, health effects: Uranium poses both radiological and chemical health risks. Chronic exposure is primarily associated with kidney damage due to its chemical toxicity as a heavy metal. The radiological risk — increased cancer probability — is also present but secondary to the nephrotoxic concern at drinking water concentrations. There is no safe threshold for radiation exposure. Limit: 0.030 mg/L (30 µg/L)
Combined Radium (-226 and -228), health effects: Radium is a bone-seeking radionuclide that accumulates in skeletal tissue after ingestion. Long-term exposure increases the risk of bone cancer and leukemia. There is no safe threshold for ionizing radiation — the MCL is set at a level balancing risk reduction with treatment feasibility. Children are particularly vulnerable due to higher rates of bone growth and calcium uptake. Limit: 5 pCi/L (combined Ra-226 and Ra-228)
Lead and Copper Rule
Monitoring and Reporting
1 violation, Dec 2024 to Feb 2025
Lead and Copper Rule
Monitoring and Reporting1 violation, Dec 2024 to Feb 2025
Monitoring and Reporting: 1 violation, Dec 2024 to Feb 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.

Lead and copper at the tap
The 90th percentile of the tap samples the system collected in its latest monitoring period, against EPA's action level. Levels vary between homes.

About this data
Rules violated and the list above come from EPA's SDWIS violation records, one row per violation and contaminant, grouped by the rule each row belongs to. A violation counts when its non-compliance period ended on or after Jul 1, 2023, the start of the thirteen quarters ECHO's three-year figures cover, or is still open; it is unresolved when it was still open at EPA's data refresh on Oct 7, 2026. EPA's rule code 500, "Not Regulated", is left out, as in ECHO's counts. Each rule's violation count is EPA's, and one rule can carry several: a missed monitoring round for a group of contaminants is one violation per contaminant and period. Category names are EPA's violation categories.
ECHO's own summary count of rules violated agrees with this grouping for 98.8% of active systems nationally, and its count of rules being violated for 98.7%; where they differ, the figures here follow the rows listed.
A measured value shown with a rule is the sample result EPA recorded with that violation (SDWIS viol_measure), against the limit EPA recorded on the same row (state_mcl), both in EPA's unit as written; violations without a recorded value, such as missed monitoring, show none. Other measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.
Lead and copper are the newest 90th-percentile results in EPA's SDWA data download (LCR_SAMPLES, codes PB90 and CU90), retrieved on Oct 12, 2026: for each monitoring period a system reports the 90th-percentile value of its tap samples, which EPA compares with its action level of 0.015 mg/L for lead and 1.3 mg/L for copper (40 CFR 141.80). A result is not a measurement of any one tap.

The Texas records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
