How does 311 Center compare with other water systems in Putnam County?

New York has 5,182 active transient non-community water systems, 63% 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 311 Center?

Does 311 Center have drinking water violations?

Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in October 2014. The violations listed here began between January 1993 and October 2014. By type: 9 monitoring and reporting, 2 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 9 as archived and 3 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.
