Ground Water Rule
Treatment Technique Violation Health-based2 violations, Sep 2025 to open
Treatment Technique Violation, health-based: 2 violations, open since Sep 2025. The system did not carry out a required treatment process or corrective action.
What the rule requires: The 2006 GWR requires regular sanitary surveys of groundwater systems and targeted corrective action when fecal indicators are found in source water. Systems with significant deficiencies must provide 4-log virus treatment (99.99% removal/inactivation) or fix the deficiency.
Health effects: Protects against enteric viruses, which can contaminate groundwater via cracked well casings, failing septic systems, or animal waste. Viruses persist longer in groundwater than in surface water. Hepatitis A and norovirus are the primary pathogens of concern. Limit: Treatment technique: 4-log virus treatment required when source water has fecal indicators or significant sanitary deficiencies

Public Notice Rule and Revised PN Rule
Other Violation8 violations, May 2017 to open · Public Notification Rule
Other Violation: 8 violations, 4 still open, May 2017 to open. 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.

Consumer Confidence Rule
Other Violation2 violations, Jul 2025 to open
Other Violation: 2 violations, open since Jul 2025. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.
What the rule requires: Community water systems must deliver an annual water quality report (Consumer Confidence Report) to all customers by July 1, covering the previous year. It must list all detected contaminants, compare them to MCLs, identify source water, and include educational language about lead. A violation means the report was not delivered on time or was incomplete.

Revised Total Coliform Rule
Reporting ViolationTreatment Technique Violation Health-based5 violations, Aug 2023 to Mar 2026
Treatment Technique Violation, health-based: 2 violations, Jun 2024 to Feb 2026. The system did not carry out a required treatment process or corrective action.
Reporting Violation: 3 violations, Aug 2023 to Mar 2026. The system did not report required information on time.
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.
Health effects: Total coliform bacteria indicate that the disinfection barrier has been breached or fecal contamination is entering the system. E. coli specifically indicates fecal contamination and the possible presence of disease-causing pathogens (norovirus, Salmonella, Shigella, Campylobacter). Illness can be severe in elderly, young children, and immunocompromised individuals. Limit: Zero E. coli; ≤5% of monthly samples total coliform-positive

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)

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): 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 Pennsylvania 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.
