What does “community water system” mean?

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. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 461 Arkansas systems (54%) list groundwater as their primary source.
Who owns and regulates Hardy Waterworks?

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. 8 of the 11 active systems in Sharp County (73%) are also owned by a local government.
Does Hardy Waterworks have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2024. The violations listed here began between April 1994 and January 2024. By type: 5 public notice, recordkeeping or other, 5 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (11 of them). EPA lists 9 as archived and 3 as resolved. 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. 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.
