What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Washington has 2,392 active community water systems, 51% of the state's 4,705 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 140 Washington systems (3%) list surface water as their primary source.

Who owns and regulates Lisecc?

EPA lists Lisecc as privately owned. The WA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 140 of the 183 active systems in Whatcom County (77%) are also privately owned.

Does Lisecc have drinking water violations?

Of the 12 most recent violations in EPA's records, 11 are health-based, and the most recent began in December 2025. The violations listed here began between May 2020 and December 2025. By type: 11 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (10 of them). EPA lists 8 as resolved, 3 as archived and 1 as addressed. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
