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 Bloch & Guggenheimer Co.?
EPA lists Bloch & Guggenheimer Co. as privately owned. 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. 57 of the 70 active systems in Dorchester County (81%) are also privately owned.
Does Bloch & Guggenheimer Co. have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2024. The violations listed here began between July 2009 and October 2024. By type: 7 monitoring and reporting, 2 required treatment not met, 1 reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule (7 of them). EPA lists 11 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.
