Landfill Benefits & Features

Containment Design

Pine Tree Acres Landfill is constructed predominantly with a composite liner system comprised of a 2-foot-thick re-compacted clay liner (or equivalent) overlaying a 10-foot-thick natural clay soil barrier, followed by a 60-mil high-density polyethylene liner and a 1-foot thick granular leachate collection layer.

Leachate Collection and Treatment

Leachate is a combination of precipitation mixed with the liquid generated by waste as it decomposes. A majority of leachate is directly discharged to the local sewer system where it is treated at a publicly owned water treatment facility. 

Groundwater Monitoring

The site implements an Environmental Monitoring Program consisting of 20 groundwater monitoring wells, five surface water monitoring points, and 19 gas monitoring probes. All locations are monitored in accordance with EGLE-approved monitoring plans by trained technicians, and groundwater samples are analyzed by an independent third party laboratory. Monitoring reports are submitted to EGLE for review.
