How does Radar Water Association compare with other water systems in Adams County?
By EPA's size categories, Radar Water Association is a very small system (500 people or fewer). Adams County has 49 active public water systems. Its population served is well below the county average of 525 people per system, and accounts for 0.1% of the 25,710 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 Radar 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. 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 Radar Water Association?
EPA lists Radar Water Association 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. 39 of the 49 active systems in Adams County (80%) are also privately owned.
Does Radar Water Association have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 1999. The violations listed here began between October 1991 and October 1999. By type: 8 monitoring and reporting, 3 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 10 as archived and 2 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.
