Introduction

Area of Interest Introduction

These are places where an investigation is underway and no groundwater sample result exceeded the Part 201 cleanup criteria for groundwater used as drinking water, which is 70 ppt PFOS + PFOA.  These areas are being investigated because either a source has been confirmed nearby or there is a probable source is nearby.  These areas may include residential well sampling adjacent to a suspected source, or other sampling that may suggest or confirm a source of PFAS.

Sampling starts in some areas for a variety of reasons.  Muskegon County Airport began sampling in residential areas after staff from the Michigan Department of Environment, Great Lakes, and Energy (EGLE) recognized the historical use of firefighting foam containing PFAS used at the airport and the numerous residential wells nearby.  The Kentwood Landfill was sampled by Kent County because the City of Kentwood was concerned about potential groundwater contamination from the landfill.  If on-site sampling at areas of interest results in one or more groundwater sample exceeding the part 201 cleanup criteria for groundwater used as drinking water, these will get moved to the Michigan PFAS sites page
