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. Ohio has 544 active non-transient non-community water systems, 14% of the state's 3,854 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 102 Ohio systems (2.6%) list surface water as their primary source.
Who owns and regulates Mahoning Valley Sanitary District?
EPA lists Mahoning Valley Sanitary District as owned by a local government. The OH state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 17 of the 79 active systems in Trumbull County (22%) are also owned by a local government.
Does Mahoning Valley Sanitary District have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in November 2021. The violations listed here began between September 1996 and November 2021. By type: 9 monitoring and reporting and 3 required treatment not met. The contaminant or rule involved most often is Surface Water Treatment Rule (4 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.
