2021 Water Quality Report
The annual report details the results of water quality monitoring during 2021, as required by the Safe Drinking Water Act. This report explains where your drinking water comes from, what is in it and what steps we take to keep it safe. At the end of each year, we put together a Water Quality Report (Consumer Confidence Report).
Use the report library to find the current and past years' reports.

Lead and Copper Rule & Sampling Results
In 1991, the U.S. Environmental Protection Agency (EPA) published a regulation called the Lead and Copper Rule (LCR) that requires water suppliers to control lead and copper in drinking water using corrosion control measures. Corrosion control is an effective way to reduce the release of these metals from plumbing materials into drinking water.
We recently completed our annual lead and copper sampling. No samples exceeded the lead action level of 15 ppb or the copper action level of 1.3 ppm set by the EPA and the State of Michigan. Our 90th percentile for lead is 9 parts per billion (ppb) and 0.0 parts per million (ppm) for copper.

PFAS Information and Sampling Results
In April of 2019, the State of Michigan began a statewide sampling program and sampled all the surface water systems in the state for six consecutive months. Our test results showed that our tap water concentration of PFOS and PFOA are well below the EPA lifetime health advisory of 70 part per trillion (ppt) established by the EPA and state as well as regulatory limits being discussed.
