The North Penn Area 6 Superfund Site (NPA6 Site) addresses multiple sources of contamination and a broad contaminant plume that underlies a large portion of Lansdale, Pennsylvania. Tetrachloroethene (PCE), trichloroethene (TCE), and associated degradation products are the primary contaminants of concern. EPA originally identified 26 facilities in the Lansdale area as possible sources of contamination due to their use of site-related solvents. These 26 properties were grouped into two operable units (OUs) for soil contamination that would address source control through soil remediation.You may need a PDF reader to view some of the files on this page.
