How does Halltown Pws compare with other water systems in Lawrence County?

What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Missouri has 1,612 active community water systems, 55% of the state's 2,943 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,521 Missouri systems (86%) list groundwater as their primary source.

Who owns and regulates Halltown Pws?

EPA lists Halltown Pws as owned by a local government. The MO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 6 of the 36 active systems in Lawrence County (17%) are also owned by a local government.

Does Halltown Pws have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2024. The violations listed here began between March 2000 and October 2024. By type: 6 monitoring and reporting, 4 public notice, recordkeeping or other, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 7 as resolved, 4 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
