What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Virginia has 844 active community water systems, 35% of the state's 2,420 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 162 Virginia systems (6.7%) list purchased surface water as their primary source.
Who owns and regulates Langley Air Force Base?
EPA lists Langley Air Force Base as owned by the federal government. 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.
Does Langley Air Force Base have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in December 2025. The violations listed here began between June 1980 and December 2025. By type: 6 contaminant level above the legal limit, 3 monitoring and reporting, 1 reporting, 1 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 9 as resolved and 3 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.
