Results of Airport Area Residential Well Testing Indicate Drinking Water Is Safe of 28 Properties Tested, All Showed Non-detect PFOA/PFOS Results

The Gerald R. Ford International Airport (GFIA) today announced results of its drinking water/well testing of 28 private residences as showing non-detect levels for the presence of PFOA and PFOS, the polyfluoroalkyl substances (PFAS) compounds for which the State of Michigan has established criteria.

Property owners have been informed of the non-detect results, and the Airport has also shared results with the Michigan Department of Environmental Quality (MDEQ), the Kent County Health Department (KCHD), and the Michigan Department of Health and Human Services (MDHHS).

The non-detect levels are established by State of Michigan cleanup criteria for groundwater, as protection for drinking water. The State of Michigan’s criteria for groundwater applies to two particular compounds, PFOA and PFOS, and is set at 70 parts per trillion (ppt) combined (https://www.michigan.gov/pfasresponse).

Of the 44 property owners contacted for drinking water/well testing, 28 participated, with all 28 of the wells tested showing non-detect levels for PFOA, PFOS, and 10 other compounds. (see attached results table). One property showed low detectable presences for two PFAS compounds, PFHxA (5.45 ppt) and PFBS (6.43 ppt); but these compounds are not part of the State of Michigan cleanup criteria for groundwater, and MDHHS officials (in concurrence with MDEQ and KCHD) have confirmed that these low-level results do not pose any health concerns.

Based on these findings, the Airport will now focus on continuing its multi-step evaluation process, including completion of its property site analysis and related report to the MDEQ.

“We applaud the Airport’s efforts in going above and beyond the requirements to conduct off-site residential testing, and based on the data and related results, we concur there is no need to continue additional residential testing at this time,” explained Adam London, RS, MPA, Administrative Health Officer, KCHD.
