Weekly Update on Kalamazoo County Water Quality March 28
The Michigan Department of Environmental Quality (MDEQ) continues to sample the recently installed monitoring wells in the study area. MDEQ 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 MDEQ 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. MDEQ 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 where 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 are planned for late Spring/early Summer of 2019. Attached is a map showing the study area, monitoring well locations and results from the residential and monitoring well sampling. A copy of the complete report may be found here.
