Superfund Site: WALSH LANDFILL, HONEYBROOK TOWNSHIP, PA
Superfund Site Profile
The approximate 7-acre Walsh Landfill Site, also known as the Welsh Road Landfill, is located in Honey Brook Township, Pennsylvania. The Site reportedly received mixed municipal and industrial wastes for disposal between 1963 and 1976, but disposal operations may have continued through the 1980s. Several attempts were made by the owner to obtain state and township approval for a landfill in the 1970s. Due to citizen complaints and continued non-compliance with regulations, the operation was never permitted. Waste disposal activities contaminated soil, sediment, and groundwater.
TOPICS IN FOCUS
Evapotranspiration (ET) cover systems, are increasingly being considered for use at waste disposal sites, including municipal solid waste (MSW) and hazardous waste landfills when equivalent performance to conventional final cover systems can be demonstrated.
Unlike conventional cover system designs that use materials with low hydraulic permeability (barrier layers) to minimize the downward migration of water from the cover to the waste (percolation), ET cover systems use water balance components to minimize percolation. These cover systems rely on the properties of soil to store water until it is either transpired through vegetation or evaporated from the soil surface.
