The city of Sturgis recently received test results from the Michigan Department of Environmental Quality for perfluoroalkyl and polyfluoroalkyl substances at the clean water discharge end of the city’s wastewater treatment plant.
The results report that PFAS contaminants were below the water-quality-standard limit set for surface water discharge. Clean water from the city’s wastewater treatment plant is discharged to the Fawn River as surface water.
On Oct. 11, water at the discharge end of the wastewater treatment plant was sampled by the MDEQ and tested for PFAS. The test warranted a follow up.
Results of the follow-up test showed that PFOA levels at the discharge end of the treatment plant was 3.1 parts per trillion; MDEQ’s water quality standard limit for PFOA discharge to surface water is 12,000 PPT.
The city will receive further test results on the drinking water samples taken by the MDEQ and will continue to monitor water quality of both the municipal drinking water system and surface water discharges from the treatment plant.
