How does Oaktree Academy compare with other water systems in Mason County?

By EPA's size categories, Oaktree Academy is a very small system (500 people or fewer). Mason County has 83 active public water systems. Its population served is about half of the county average of 291 people per system, and accounts for 0.6% of the 24,180 people reported by systems filed under the county. Across Michigan, the 10,599 active systems average 847 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Oaktree Academy 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. Michigan has 1,402 active non-transient non-community water systems, 13% of the state's 10,599 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 10,214 Michigan systems (96%) list groundwater as their primary source.

Who owns and regulates Oaktree Academy?

EPA lists Oaktree Academy as privately owned. The MI state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 74 of the 83 active systems in Mason County (89%) are also privately owned.

Does Oaktree Academy have drinking water violations?

EPA's records list 4 violations for this system; none is health-based, and the most recent began in October 2019. The violations listed here began between January 1994 and October 2019. By type: 3 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 3 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.
