Does Rock Spring Cafe have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in November 2025. The violations listed here began between January 1986 and November 2025. By type: 8 monitoring and reporting, 1 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Nitrate (5 of them). EPA lists 6 as resolved, 2 as unaddressed and 2 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.
