Groundwater means the system draws its water from wells or springs fed by underground aquifers. 7,096 New York systems (87%) list groundwater as their primary source.
Who owns and regulates Hillside Apts?

Does Hillside Apts have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in May 2023. The violations listed here began between June 1993 and May 2023. By type: 8 monitoring and 4 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (8 of them). EPA lists 9 as resolved and 3 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.
