| Abstract |
The Heleva Landfill site consists of a 20-acre landfill located on a 93-acre tract of land in Lehigh County, Pennsylvania. The site is surrounded primarily by farm and pasturelands, with the village of Ormrod (population approximately 100) and town of Ironton (population 150) located approximately one quarter mile away. The site began operations as a sanitary landfill in 1967, accepting 250-350 tons/day of mixed refuse including paper, wood, and orchard wastes. In addition, industrial wastes with high levels of trichloroethylene (200 micrograms/liter) was sent to the site as early as 1967. The site was closed in May of 1981 by the Pennsylvania Department of Environmental Resources because of operational deficiencies. The selected remedy for the Heleva Landfill site consists of extending an existing water main from Ormrod to Ironton, capping the entire 20-acre landfill according to RCRA standards, constructing surface water diversion and gas venting systems, conducting a pre-design study to fully delineate the source of contamination and determine sinkhole activity, constructing a treatment facility on-site, pumping and treating highly contaminated ground water, monitoring and sampling existing wells and surface water, and conducting operations and maintenance for a period of at least two years. The total capital cost of the selected remedial alternative is estimated to be $7,253,000. |
