Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 44 Tennessee systems (3.2%) list groundwater under influence of surface water as their primary source.
Who owns and regulates St Joseph Water System?

Does St Joseph Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2025. The violations listed here began between April 2020 and July 2025. By type: 6 public notice, recordkeeping or other, 3 monitoring and 3 monitoring and reporting. The contaminant or rule involved most often is Consumer Confidence Rule (4 of them). EPA lists 6 as resolved, 3 as addressed, 2 as unaddressed 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
