State PFAS effort leads to improving water quality in Kalamazoo River

LANSING, Mich --The Michigan Department of Environmental Quality (MDEQ) today announced that it will allow the city of Kalamazoo to reduce the frequency of monitoring for per and polyfluoroalkyl substances (PFAS) at its wastewater treatment plant after testing confirmed that the plant’s discharges are meeting water quality standards.
Weekly monitoring data from water entering and leaving the plant during the past six months has shown a steady drop of PFAS being discharged into the Kalamazoo River. PFAS discharges from the wastewater treatment plant to the river have been below the state’s Rule 57 water quality standards for PFAS since August of 2018.
MDEQ Director Liesl Clark credits the improving PFAS numbers in the river to the state’s Industrial Pretreatment Program (IPP) and public water system testing program. Both programs are key elements of the Michigan PFAS Action Response Team’s (MPART) multi-faceted approach to reducing the public’s exposure to unacceptably high levels of PFAS.
“Our success in driving down PFAS levels in the Kalamazoo River is a direct result of MPART’s work to identify and mitigate sources of PFAS contamination,” Clark said. “In this case, our IPP program identified and eliminated PFAS discharges from the abandoned Production Plated Plastics site and our public water system program identified the contaminated municipal wells in Parchment – both of which were threatening public health and polluting the Kalamazoo River.”
Under the state’s IPP initiative launched in February 2018, Kalamazoo officials were able to trace PFAS contamination entering the wastewater treatment plant to the site of the former Production Plated Plastics plant upstream in nearby Richland. In response, the MDEQ installed a $700,000 carbon filtration system at the site using MPART funding. Treated water entering the city’s sanitary sewer system is now testing non-detect for PFAS.
The discovery of PFAS at the site also launched an MPART-led investigation into drinking water well contamination in Richland and the supply of alternative water to several homes in the area. www.michigan.gov/pfasresponse/0,9038,7-365-86511_82704-473485--,00.html
In July 2018, MPART’s proactive public water system testing also identified high levels of PFAS in the city of Parchment’s water supply well above the USEPA Lifetime Health Advisory of 70 parts per trillion for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) combined.
As a result of this discovery, the three Parchment municipal wells near the banks of the Kalamazoo river were shut down and the people of Parchment were immediately supplied alternative water. Working with MPART, Kalamazoo public works officials quickly developed an innovative plan to flush the Parchment water system through the Kalamazoo waste water treatment plant, reducing PFAS impacts to the river. Customers of the Parchment municipal system were then connected to the city of Kalamazoo’s municipal water system. www.michigan.gov/pfasresponse/0,9038,7-365-86511_82704_87495---,00.html
“The city of Kalamazoo was proud to work in partnership with the state’s MPART organization through both the Richland and Parchment PFAS responses,” said James Baker, Director of the city of Kalamazoo’s Department of Public Services. “This unified approach that brought together state and local resources with bipartisan support from elected officials resulted in thousands of citizens being protected from previously unknown contaminants in their drinking water.”
Working with MDEQ, Kalamazoo water treatment officials continue work with local industrial users to identify other potential sources of PFAS within their facilities and implement plans to reduce or eliminate PFAS from their manufacturing processes.
“MPART’s work is far from done,” Clark added. “But the example of the Kalamazoo watershed shows that Michigan is a national leader in responding to PFAS contamination and proves that a proactive, collaborative approach can result in cleaner water for more Michiganders.”
