How does Miller compare with other water systems in Lewis County?
By EPA's size categories, Miller is a small system (501 to 3,300 people). Lewis County has 166 active public water systems. Its population served is about 74% above the county average of 537 people per system, and accounts for 1% of the 89,186 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Miller is about twice that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Washington has 400 active non-transient non-community water systems, 8.5% 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 Miller?
EPA lists Miller 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. 117 of the 166 active systems in Lewis County (70%) are also privately owned.
Does Miller have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2020. The violations listed here began between October 2004 and January 2020. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Diquat (6 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.
