How does Prospect Charter School compare with other water systems in Jackson County?

By EPA's size categories, Prospect Charter School is a very small system (500 people or fewer). Jackson County has 200 active public water systems. Its population served is well below the county average of 983 people per system, and accounts for 0.1% of the 196,508 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 Prospect Charter School is about 33% 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 Prospect Charter School?

EPA lists Prospect Charter School 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 200 active systems in Jackson County (16%) are also owned by a local government.

Does Prospect Charter School have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2025. The violations listed here began between January 1999 and July 2025. By type: 8 monitoring and reporting, 2 monitoring, 1 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 8 as resolved, 2 as unaddressed and 2 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
