How does Rocky Gap State Park compare with other water systems in Allegany County?
By EPA's size categories, Rocky Gap State Park is a very small system (500 people or fewer). Allegany County has 53 active public water systems. Its population served is well below the county average of 1,293 people per system, and accounts for 0.3% of the 68,550 people reported by systems filed under the county. Across Maryland, the 2,992 active systems average 1,947 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Rocky Gap State Park is about half of 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. Maryland has 491 active non-transient non-community water systems, 16% of the state's 2,992 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 31 Maryland systems (1%) list surface water as their primary source.
Who owns and regulates Rocky Gap State Park?
EPA lists Rocky Gap State Park as owned by a state government. The MD state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 7 of the 53 active systems in Allegany County (13%) are also owned by a state government.
Does Rocky Gap State Park have drinking water violations?
EPA's records list 7 violations for this system; 3 are health-based, and the most recent began in October 2024. The violations listed here began between July 1996 and October 2024. By type: 3 monitoring and reporting, 2 required treatment not met, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule (4 of them). EPA lists 6 as resolved and 1 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.
