Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,118 Georgia systems (89%) list groundwater as their primary source.
Who owns and regulates Walnut Grove Subdivision?

Does Walnut Grove Subdivision have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between July 2009 and October 2025. By type: 7 public notice, recordkeeping or other, 2 monitoring, 2 monitoring and reporting and 1 reporting. The contaminant or rule involved most often is Consumer Confidence Rule (7 of them). EPA lists 7 as resolved, 4 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. 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.
