How does Rocky Knoll Elementary compare with other water systems in Berkeley County?
By EPA's size categories, Rocky Knoll Elementary is a very small system (500 people or fewer). Berkeley County has 23 active public water systems. Its population served is well below the county average of 4,234 people per system, and accounts for less than 0.1% of the 97,378 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 Rocky Knoll Elementary 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 Rocky Knoll Elementary?
EPA lists Rocky Knoll Elementary 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. 6 of the 23 active systems in Berkeley County (26%) are also owned by a local government.
Does Rocky Knoll Elementary have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in November 2025. The violations listed here began between January 2023 and November 2025. By type: 10 monitoring and reporting, 1 public notice, recordkeeping or other and 1 monitoring. The contaminants or rules involved are Public Notice, Groundwater Rule, Nitrate and Revised Total Coliform Rule. EPA lists 11 as archived and 1 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.
