How does Hampton Water Association compare with other water systems in Whatcom County?

By EPA's size categories, Hampton Water Association is a very small system (500 people or fewer). Whatcom County has 183 active public water systems. Its population served is well below the county average of 1,437 people per system, and accounts for less than 0.1% of the 263,011 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active community water system reports serving 6,703 people, so Hampton Water Association is well below that figure.

What does “community water system” mean?

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. Washington has 2,392 active community water systems, 51% of the state's 4,705 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 53 Washington systems (1.1%) list purchased groundwater as their primary source.

Who owns and regulates Hampton Water Association?

Does Hampton Water Association have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2024. The violations listed here began between December 1991 and July 2024. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 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.
