How does Pinnacle Technology compare with other water systems in Monroe County?

By EPA's size categories, Pinnacle Technology is a very small system (500 people or fewer). Monroe County has 83 active public water systems. Its population served is well below the county average of 1,703 people per system, and accounts for less than 0.1% of the 141,308 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 Pinnacle Technology 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 Pinnacle Technology?

EPA lists Pinnacle Technology 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. 73 of the 83 active systems in Monroe County (88%) are also privately owned.

Does Pinnacle Technology have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 2024. The violations listed here began between September 2006 and December 2024. By type: 8 monitoring and reporting, 3 monitoring 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 11 as resolved and 1 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.
