How does National Radio Astronomy Observatory compare with other water systems in Pocahontas County?
By EPA's size categories, National Radio Astronomy Observatory is a very small system (500 people or fewer). Pocahontas County has 38 active public water systems. Its population served is about half of the county average of 212 people per system, and accounts for 1.3% of the 8,055 people reported by systems filed under the county. Across West Virginia, the 791 active systems average 2,032 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so National Radio Astronomy Observatory is well below that figure.
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 means the system draws its water from wells or springs fed by underground aquifers. 468 West Virginia systems (59%) list groundwater as their primary source.
Who owns and regulates National Radio Astronomy Observatory?
EPA lists National Radio Astronomy Observatory as owned by a local 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. 8 of the 38 active systems in Pocahontas County (21%) are also owned by a local government.
Does National Radio Astronomy Observatory have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in March 2026. The violations listed here began between July 1994 and March 2026. By type: 7 monitoring and reporting, 1 required treatment not met, 1 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Lead and Copper Rule (4 of them). EPA lists 5 as resolved, 3 as archived and 2 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.

All 10 violations in EPA's records, newest first.Labels and codes come from EPA's SDWIS reference tables. A monitoring or reporting violation means a required test or report was missed or late; it does not by itself mean a contaminant was found. "Health-based" marks violations of a legal limit or required treatment.

Is National Radio Astronomy Observatory's water safe to drink?
AquaCensus shows EPA compliance records, not current water test results, so it cannot say whether the water is safe at a given moment. EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in March 2026. For current results, consult EPA ECHO, or the WV state drinking water program.
Where can I find National Radio Astronomy Observatory's water quality report?
