One of the new requirements for the revised LCR is how water samples are collected. The new sampling guidelines require that the first and fifth liter of tap water is collected in homes with lead service lines. The first liter represents water from household fixtures, and the fifth is likely to represent water from the lead line.

In 2022, 50 homes were sample in the city.
The final water sampling results did not exceed the allowable lead level of 15 parts per billion (ppb) or the allowable copper level of 1.3 parts per million (ppm). The EPA and the state of Michigan set the allowable levels. The water testing results for 2022 are 14 parts per billion (ppb) for lead and 0.0 parts per million (ppm) for copper.
Since 2019, the new sampling requirements have resulted in a slight increase in the lead levels detected in the system. The water sampling results do not exceed the allowable lead level of 15 (ppb).
