Muskegon County Airport Drinking Water Well Sample Area MapSummary

Based on Federal Aviation guidelines, Muskegon County Airport (airport) was required to conduct regular firefighting training using firefighting foam, also known as Aqueous Film Forming Foam or AFFF.  Given this historical information and the presence of residential drinking water wells, the Michigan Department of Environment, Great Lakes, and Energy (EGLE) requested that Muskegon County sample residential wells in the vicinity of former firefighting training areas. Starting in August of 2018, Muskegon County sampled the drinking well water from 127 homes. Perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) were detected in samples from six homes at concentrations exceeding the Lifetime Health Advisory (LHA) of 70 parts per trillion (ppt). Public Health - Muskegon County provided bottled water and point of use filters to these homes. In the summer of 2019, EGLE provided funding to connect municipal water to the six homes where exceedances of the LHA were detected.

In late August and September 2019, EGLE sampled drinking water wells at additional homes in the vicinity of an airplane crash that occurred on airport property in the early 1980s. Based upon detections of moderate levels (below LHA) of PFOS+PFOA in several drinking wells in this area, EGLE expanded the sample area to include 35 additional homes. Public Health – Muskegon County is offering point-of-use filters to each house in the investigation area with detections of any per- and polyfluoroalkyl substances (PFAS) compound. On October 7, 2019, EGLE started an environmental investigation which consists of the collection of soil and groundwater samples on and near the airport and the measurement of water table elevations. This information will be used to gain a better understanding of the distribution of PFAS contamination. Additionally, EGLE is currently resampling the homes that were previously sampled by Muskegon County to determine if PFAS concentrations are staying consistent.
