Abstract |
The Millcreek site located in Millcreek Township, Erie County, Pennsylvania, was filled with foundry sand and industrial and municipal waste such as halogenated volatile solvents. This disposal has resulted in significant ground water contamination both on- and offsite. The major classes of compounds detected included: polychlorinated biphenyls (PCBs), polynuclear aromatic hydrocarbons (PAHs), phthalates, volatile organics, phenols and metals such as lead and copper. The selected remedial action for this site includes: excavation and consolidation of contaminated soil and sediments under a RCRA cap to meet proposed criteria; site grading; placing a soil cover over remaining low level contaminated soils not exceeding the proposed criteria; construction of surface water management basins and ditches; revegetation of soil cover and cap; installation of additional monitoring wells; construction of a flood retention basin on property owned by Millcreek Township; pumping and treating of contaminated ground water; additional sampling and well installation and ground water monitoring. |
