Liberty Environmentalists Landfill (Clark Lake, Jackson County)
EGLE Site Lead: Brett Coulter, CoulterB1@Michigan.gov or 517-614-7714. Webpage last updated August 3, 2020.
Liberty Environmentalist Landfill is located at 7900 South Meridian Road in Jackson County and has been in operation since 1985. The landfill has a double clay liner, leachate collection system and monitoring system.
PFAS testing was conducted due to the MPART initiative, leachate PFAS results, and the proximity of the site to the Grand River. PFAS samples were collected from six monitor wells. One sample at well MW 30 exceeded the drinking water criteria for PFOA; it was 9.4 ppt.
The Grand River is adjacent to the property on the west and south property lines. Wetlands exist on the property and between the eastern most and western most landfill cells. The groundwater flow is generally to the southeast on the eastern portion of the property (Phase I, II, and IV) and to the west on the western portion of the property (Phase III). Groundwater flow is greatly influenced by local topography and the Grand River water levels. Residential wells in the vicinity are side-gradient and up-gradient and in a lower aquifer.
- Five monitor wells were sampled by TRC Environmental, Inc., for PFAS on July 23, 2019, and one monitor well on September 27, 2019.The groundwater and leachate samples were analyzed for PFAS by Eurofins TestAmerica Laboratories, Inc.
- EGLE staff will recommend quarterly PFAS monitoring as an addition to the groundwater monitoring plan for the facility.
Residential Well Testing/Alternate Water Information
- No sampling of residential wells is planned because nearby residential wells are side-gradient and up-gradient and in a lower aquifer.
Upcoming Community Engagement
- None scheduled at this time.

|Groundwater||July 2019 - September 201||6||1||1|
*Groundwater results are compared to EGLE Part 201 Criteria of PFOS 16 ppt and PFOA 8 ppt.
- Five samples were collected on July 23, 2019, instead of six, due to an inaccessible well.The well (MW-24R) was sampled for PFAS in September 2019.Quality control was conducted by the analytical laboratory.
