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. Delaware has 82 active non-transient non-community water systems, 17% of the state's 494 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 459 Delaware systems (93%) list groundwater as their primary source.
Who owns and regulates Baltimore Aircoil?
EPA lists Baltimore Aircoil as privately owned. The DE state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 118 of the 136 active systems in Kent County (87%) are also privately owned.
Does Baltimore Aircoil have drinking water violations?
EPA's records list 5 violations for this system; all are health-based, and the most recent began in April 2011. The violations listed here began between October 1979 and April 2011. By type: 5 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 4 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.
