Pennsylvania has 4,429 active transient non-community water systems, 61% of the state's 7,217 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,632 Pennsylvania systems (92%) list groundwater as their primary source.
Who owns and regulates Pymatuning Lab of Ecology?
EPA lists Pymatuning Lab of Ecology as under public/private ownership.

Does Pymatuning Lab of Ecology have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in April 2025. The violations listed here began between October 2010 and April 2025. By type: 3 monitoring, 3 public notice, recordkeeping or other, 2 monitoring and reporting, 2 required treatment not met, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
