Ground Water Rule
Monitoring and Reporting1 violation, Jun 2025 to Jul 2025 · E. coli (Escherichia coli)
Monitoring and Reporting: 1 violation, Jun 2025 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.
Contaminant on the record: E. coli (Escherichia coli).
Lead and Copper Rule
Monitoring and Reporting
1 violation, Oct 2022 to Sep 2025
Lead and Copper Rule
Monitoring and Reporting1 violation, Oct 2022 to Sep 2025
Monitoring and Reporting: 1 violation, Oct 2022 to Sep 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.

Reporting Violation1 violation, Jul 2025 to Apr 2026
Reporting Violation: 1 violation, Jul 2025 to Apr 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.

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.
Measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.

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.
