How does Xelapack compare with other water systems in Washtenaw County?
By EPA's size categories, Xelapack is a very small system (500 people or fewer). Washtenaw County has 262 active public water systems. Its population served is well below the county average of 1,147 people per system, and accounts for less than 0.1% of the 300,406 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 Xelapack 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 Xelapack?
EPA lists Xelapack 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. 229 of the 262 active systems in Washtenaw County (87%) are also privately owned.
Does Xelapack have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2019. The violations listed here began between January 2017 and July 2019. By type: 9 monitoring and reporting and 3 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 9 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.
