What does “community water system” mean?

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 Lisbon Water District?

The NY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 34 of the 229 active systems in St. Lawrence County (15%) are also owned by a local government.
Does Lisbon Water District have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2017. The violations listed here began between October 1996 and October 2017. By type: 6 monitoring and reporting and 6 public notice, recordkeeping or other. The contaminant or rule involved most often is Consumer Confidence Rule (4 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.
