Plainfield Township's Municipal Water System

Plainfield Township's Municipal Water System reflects known PFAS levels. Based on environmental and health concerns, further review and possible action may be necessary to best protect public health. More details about this location will be made available as soon as possible.

  • In June 2013 PFAS were detected at levels less than 70 ppt during federal testing for unregulated contaminants at the water treatment plant, which has blended well sources.
  • Anticipating the EPA’s lowering of the provisional Health Action Level to 70 ppt in 2016, the township conducted individual sampling at wells in Versluis Park. The results were higher than the previous results from the water plant.
  • The township limited exposure to PFAS in their drinking water by removing the Versluis wells from service. They continue to search for a replacement water source that is free of PFAS compounds.
  • The township conducts quarterly testing at the water plant to ensure stable levels and has recently sampled all the remaining wells individually. Sample results average 8.1 ppt at the water plant.
  • A pilot study grant was awarded to the township by the DEQ to study PFAS removal by retrofitting the existing filters. The grant was signed by the MDEQ and into effect on 5/14/18. Construction is underway.
  • The DEQ is investigating potential sources of the PFAS contamination.
  • The township is conducting preliminary engineering work to extend water service to customers affected by the Wolverine Worldwide contamination in Belmont.
  • The public water supply sampling results are summarized in the table below.
