How does Ewellix compare with other water systems in Macomb County?
By EPA's size categories, Ewellix is a very small system (500 people or fewer). Macomb County has 92 active public water systems. Its population served is well below the county average of 9,021 people per system, and accounts for less than 0.1% of the 829,966 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 Ewellix 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 Ewellix?
EPA lists Ewellix 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. 70 of the 92 active systems in Macomb County (76%) are also privately owned.
Does Ewellix have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2016. The violations listed here began between January 2014 and October 2016. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Nitrate (2 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.
