How does Deer Mountain Inn compare with other water systems in Greene County?
By EPA's size categories, Deer Mountain Inn is a very small system (500 people or fewer). Greene County has 195 active public water systems.

Does Deer Mountain Inn have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2025. The violations listed here began between July 1997 and April 2025. By type: 8 monitoring and reporting and 4 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 7 as archived and 5 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.
