The 1,293-acre Tobyhanna Army Depot site is located in Monroe County, Pennsylvania. From the 1950s to early 1960s, the Army used areas on the southern part of the site for burning and disposal of garbage, construction rubble, scrap metal, drums and solvents. Drum staging and disposal of building materials and construction waste took place on another part of the site. Waste disposal activities contaminated sediment and groundwater. Following cleanup, EPA took part of the site off the Superfund program�s National Priorities List (NPL) in 2001. Monitored natural attenuation of groundwater is ongoing.
