How does Three Rivers School District Office compare with other water systems in Josephine County?
By EPA's size categories, Three Rivers School District Office is a very small system (500 people or fewer). Josephine County has 150 active public water systems. Its population served is well below the county average of 403 people per system, and accounts for less than 0.1% of the 60,442 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Three Rivers School District Office 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. Oregon has 346 active non-transient non-community water systems, 14% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.
Who owns and regulates Three Rivers School District Office?
EPA lists Three Rivers School District Office as owned by a local government. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 32 of the 150 active systems in Josephine County (21%) are also owned by a local government.
Does Three Rivers School District Office have drinking water violations?
EPA's records list 6 violations for this system; 1 is health-based, and the most recent began in May 2016. The violations listed here began between October 1992 and May 2016. By type: 3 monitoring and reporting, 2 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 3 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.
