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. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,870 Maryland systems (96%) list groundwater as their primary source.
Who owns and regulates Fallston High School?
EPA lists Fallston High School as owned by a local 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. 45 of the 226 active systems in Harford County (20%) are also owned by a local government.
Does Fallston High School have drinking water violations?
EPA's records list 10 violations for this system; 2 are health-based, and the most recent began in January 2025. The violations listed here began between April 1991 and January 2025. By type: 7 monitoring and reporting, 1 monitoring, 1 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Lead and Copper Rule (5 of them). EPA lists 8 as resolved and 2 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.
