Cascade Township Residential Wells

Updated: March 12, 2019

Map of Cascade Township AreaSummary

Approximately 49 residential drinking water wells along Trout Creek in the neighborhood east of the 36th Street exist off I-96 and west of Tricklewood Drive will be sampled by the Michigan Department of Environmental Quality (MDEQ) for PFAS as part of the ongoing investigation of potential PFAS contamination sources in Cascade Township. This area has been selected due to its proximity to known and potential PFAS sources and local geologic features. The MDEQ expects to reach out to all property owners in the study area by postage mail by March 22, 2019. If you are contacted, please participate.

The MDEQ is evaluating all commercial activities near Cascade Township that have or may have used materials containing PFAS as part of their operations. In addition to the two known PFAS sources, Lack’s Industries – Cascade, and Gerald R. Ford International Airport (GFIA), the MDEQ is also evaluating the sampling results from the MPART Industrial Pre-treatment Program (IPP). The information gathered from the IPP has also identified other PFAS users in the area, but at locations without confirmed releases of PFAS-containing materials to the environment. In addition, the MDEQ completed an internal geologic review of the area surrounding GFIA and concluded that the relationship of known PFAS conditions in the area and the local geology warranted further investigation in the area northeast of GFIA. Specifically, the review recommended that this be accomplished through private residential drinking water well sampling.

Residents of the selected study area will be contacted directly by the MDEQ and their consultant, Wood, Inc., by mail and phone.

Note: Residents previously sampled as part of the sampling efforts by Gerald R. Ford International Airport or by Lacks Industries will not be resampled. Residents who provided independent PFAS results that were non-detect or were below 5 ppt total PFAS will not be contacted.

If you are not contacted by MDEQ in March 2019 and think that your residence may be in the study area, you may contact Aaron Assmann MDEQ project manager in Grand Rapids at 616-430-5275 or AssmannA@michigan.gov.

Sample results could take up to 4-6 weeks to return. Once results become available, they will be emailed / mailed to property owners to an address of their choice, along with an explanation of the results compared to health advisory levels. The results will be shared with the Michigan Department of Health and Human Services (MDHHS) and the Kent County Health Department (KCHD) so that they can help answer any health-related questions and take the appropriate action regarding public health.
