By EPA's size categories, Walnut Flats is a very small system (500 people or fewer). Giles County has 25 active public water systems.

What does “transient non-community water system” mean?

Virginia has 1,133 active transient non-community water systems, 47% of the state's 2,420 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,089 Virginia systems (86%) list groundwater as their primary source.
Who owns and regulates Walnut Flats?

The VA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 3 of the 25 active systems in Giles County (12%) are also owned by the federal government.
Does Walnut Flats have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in July 2025. The violations listed here began between August 2001 and July 2025. By type: 5 contaminant level above the legal limit, 2 monitoring, 2 public notice, recordkeeping or other, 2 monitoring and reporting and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 6 as resolved and 6 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.
