The Croydon TCE site is in Bristol Township, Bucks County, Pennsylvania. A series of studies conducted by EPA beginning in 1984 led to the detection of VOC contamination in the ground water over a 3.5-square mile area referred to as the study area. The area is composed of the Croydon residential community and several manufacturing and commercial establishments. The 1990 ROD addresses the remediation of the ground water contamination at the site. The primary contaminants of concern affecting the ground water are VOCs including TCE and 1,1-DCE. The selected remedial action for the site includes ground water pumping and onsite treatment using air stripping, followed by carbon adsorption as an ancillary treatment step before onsite discharge of the treated ground water; vapor-phased carbon adsorption treatment of air stripper exhaust, followed by offsite disposal or treatment of spent carbon and ground water monitoring. The estimated present worth cost for this remedial action is $1,345,000, which includes an estimated annual O and M cost of $46,709 for 45 years.
