What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Virginia has 443 active non-transient non-community water systems, 18% 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 Nasa Wallops Island?

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. 2 of the 69 active systems in Accomack County (2.9%) are also owned by the federal government.
Does Nasa Wallops Island have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in November 2023. The violations listed here began between July 1986 and November 2023. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit and 2 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 8 as archived and 4 as resolved. 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. 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.
