How does Carson Industrial Site compare with other water systems in Skamania County?
By EPA's size categories, Carson Industrial Site is a very small system (500 people or fewer). Skamania County has 56 active public water systems. Its population served is well below the county average of 335 people per system, and accounts for 0.3% of the 18,736 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 Carson Industrial Site is well below 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 Carson Industrial Site?
EPA lists Carson Industrial Site as owned by a local government. 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. 10 of the 56 active systems in Skamania County (18%) are also owned by a local government.
Does Carson Industrial Site have drinking water violations?
EPA's records list 9 violations for this system; 1 is health-based, and the most recent began in April 1998. The violations listed here began between October 1991 and April 1998. By type: 8 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 8 as archived and 1 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.
