New York has 704 active non-transient non-community water systems, 8.6% of the state's 8,167 active systems. 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 Garrison Union Free School?

EPA lists Garrison Union Free School as privately owned. 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. 342 of the 382 active systems in Putnam County (90%) are also privately owned.

Does Garrison Union Free School have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2000. The violations listed here began between June 1993 and December 2000. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 11 as archived and 1 as resolved. 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. 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.
