The 25-acre Heleva Landfill site is a former sanitary landfill in North Whitehall Township, Lehigh County, Pennsylvania. A 1985 Record of Decision (ROD) addressed onsite ground water contamination and provided for extending an existing water main; capping the entire landfill; constructing surface water diversions and gas venting systems; constructing an onsite ground water treatment facility; and establishing a pumping and treating system. Construction of all of these major remedial activities has been completed except for the ground water extraction and treatment component. The ROD amends the ground water component. The primary contaminants of concern affecting the ground water are VOCs including benzene, PCE, TCE, toluene, and xylenes. The amended remedial action for the site includes continuing with the selected remedy from the previous ROD and replacing the ground water portion with extracting near gradient ground water to contain the highly contaminated dissolved plume.
