Landfill Environmental Protection Systems
The CWM Landfill is engineered with overlapping environmental protection systems that meet or exceed rigorous state and federal regulations. The facility is double-lined throughout the landfill and triple-lined at the lowest area. The primary, secondary and tertiary liners are made of different materials including 60 mil High Density Polyethyline (HPDE) and geosynthetic clay (geotextile and bentonite composites). The site also includes a state-of-the-art leachate collection system and groundwater monitoring wells.
