A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. 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 Lincoln 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. 12 of the 14 active systems in Washington County (86%) are also owned by a local government.
Does Lincoln Waterworks 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 2023. The violations listed here began between July 1998 and November 2023. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit, 1 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 8 as resolved and 4 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.
