Homes, apartments and mobile-home parks are served by these. Arkansas has 660 active community water systems, 77% of the state's 853 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 237 Arkansas systems (28%) list purchased surface water as their primary source.

Who owns and regulates Chester Water Works?

EPA lists Chester Water Works as owned by a local government. The AR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 13 of the 15 active systems in Crawford County (87%) are also owned by a local government.

Does Chester Water Works have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2022. The violations listed here began between July 2016 and December 2022. By type: 6 monitoring, 5 reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (11 of them). EPA lists 8 as resolved, 3 as addressed 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement. 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.
