The City of Perry conducts routine testing of tap water in homes for lead and copper. We recently collected samples from 10 homes. Two homes had copper results above the Action Level.
The Department of Environment, Great Lakes, and Energy (EGLE) evaluates compliance with the Action Level based on the 90th percentile of lead and copper results collected in each round of sampling. The “Action Level” is a measure of corrosion control effectiveness. An “Action Level exceedance” means that more than 10% of the homes tested have results over 1.3ppm.
The copper 90th percentile for the City’s water supply is 2.2 parts per million (ppm), which exceeds the Action Level of 1.3 ppm.
The Action Level exceedance is not a violation, but triggers additional actions including:
- educational outreach to customers,
- increased sampling every six months,
- an assessment of corrosion control.
Michigan’s Department of Health and Human Services has provided these resources regarding the results:

In the coming months, DPW will be collecting samples from 20 homes within the community. If you receive a sample collection kit, it’s necessary to follow all instructions and fill out the paperwork completely. Your cooperation is appreciated.
