Water quality in Virginia
Of the 7 Virginia ZIPs matched to an EPA SDWIS community water system, none reports a health-based violation in the last 3 years, though 2 carry at least one non-health-based violation. 3 further ZIPs have no water-system record on zipradar yet. That is a gap in our records, not a sign that the water is untested. SDWIS reports the system serving the county, never an address-level test, and never private wells.
