How does Usgs Leetown Science Center compare with other water systems in Jefferson County?

By EPA's size categories, Usgs Leetown Science Center is a very small system (500 people or fewer). Jefferson County has 44 active public water systems. Its population served is well below the county average of 787 people per system, and accounts for 0.3% of the 34,629 people reported by systems filed under the county.

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. West Virginia has 55 active non-transient non-community water systems, 7% of the state's 791 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 22 West Virginia systems (2.8%) list groundwater under influence of surface water as their primary source.

Who owns and regulates Usgs Leetown Science Center?

EPA lists Usgs Leetown Science Center as owned by the federal government. The WV 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 44 active systems in Jefferson County (6.8%) are also owned by the federal government.

Does Usgs Leetown Science Center have drinking water violations?

Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in February 2026. The violations listed here began between July 2024 and February 2026. By type: 6 monitoring and reporting, 3 public notice, recordkeeping or other, 2 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (4 of them). EPA lists 5 as unaddressed, 5 as archived and 2 as resolved. 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. 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.
