Weekly Water Quality Update
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) continues to sample the recently installed monitoring wells in the study area. EGLE has started to receive results back from the monitoring well sampling. Additional monitoring well sampling is planned for the next 2 weeks. Once all of the monitoring well results are received the EGLE will begin developing additional maps, cross sections and conceptual site models to better understand the contamination and develop a strategy for additional investigation activities. Residential well sampling in the expanded study area has also been completed. EGLE collected 33 residential well samples in this area and have received all of the results back. Preliminary review of the results looks very positive as none of the samples exceeded the 70 ppt health advisory value. 30 out of the 33 residential samples were non-detect. Michigan Department of Health and Human Services (MDHHS) and Kalamazoo County Health & Community Services Department provided notification to these residents of the sampling, and out of an abundance of caution, all residents in the expanded residential water well program area and buffer zone have been offered PFAS filters. Proposed surface water sampling and irrigation well sampling activities has started in Richland in the study area. 10 samples have been collected to date and the results will be added to the updated map attached to this press release.
As the summer recreation season is drawing closer, the Michigan Department of Health and Human Services (MDHHS) is issuing a reminder that everyone should avoid foam on Michigan lakes and rivers known to have per and poly-fluoroalkyl substances (PFAS) in the water. Foam on these water bodies can have much higher amounts of PFAS than the water, and swallowing foam with PFAS could be a health risk.
Health advisories for foam exist on these waterbodies:
- Van Etten Lake, Oscoda.
- Lake Margrethe, Grayling.
- Rogue River, Rockford.
- Thornapple River, Grand Rapids.
- Huron River, Southeast Michigan.
Swimming or bathing in water containing PFAS is not a health concern because the amount of PFAS is typically low compared to the foam. Although swallowing PFAS is the main way to get it in your body, an accidental swallow of river or lake water is not a health concern.
