![]() This table was updated to include all seven PFAS criteria effective. Data prior to is reflected in the timeline below. Residential Well Testing/Alternate Water Information Currently, EGLE has no plans to conduct any further sampling of Walker Landfill or surrounding properties because the contaminated groundwater is not poising a risk to the sensitive receptors in the area. It appears as it did with historical known contamination, the waste of the landfill is in clay formation and groundwater is only slightly migrating to the south and west. Based on the results of the second round of PFAS sampling, it appears at this time the sensitive receptors (i.e., surface water and drinking water wells) are not being impacted by the contamination from the landfill.On Decemthe sampling maps were updated to include all groundwater sampling to date.The highest PFOS and/or PFOA groundwater sample was 4,130 ppt for PFOA and 41.8 ppt for PFOS. On September 9, 2020, EGLE received the sample results.The lakes do have residential homes and are utilized for recreational purposes. Crooked Lake and Mitchell Lake are located to the west and north of the landfill. The most recent groundwater flow maps are from the early 2000s. The deep aquifer has more of a northernly flow. Based on the documented types of wastes accepted, it is highly likely PFAS was part of the automotive waste and garbage.īased on historical groundwater flow direction, the shallow aquifer(s) have been mapped in every direction over time. ![]() The landfill was licensed by the State of Michigan to accept wastes under Act 87 from 1966 to 1974. Prior to a 1965 court order, Walker Landfill reportedly accepted thousands of drums of paint sludge and other wastes related to the automotive industry and disposed in unlined lagoons. Walker Landfill is located at 5001 31 Mile Road, Washington Township. Web content may not routinely be updated on this page.
