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. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,370 Washington systems (93%) list groundwater as their primary source.

Who owns and regulates Belfern West?

Does Belfern West have drinking water violations?

Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in January 2017. The violations listed here began between September 2004 and January 2017. By type: 6 contaminant level above the legal limit, 5 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (5 of them). EPA lists 9 as resolved and 3 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.
