Stage of Clean-up: Study Underway
Conditions at Proposal (September 5, 2002): The Ward Transformer site is located near the Raleigh Durham International Airport in a predominantly industrial area of Raleigh, Wake County, North Carolina. The site encompasses an active electrical transformer building/reconditioning facility constructed in 1964 on 11 acres of previously undeveloped land. A perennial stream bordered by wetlands leads from the property to a recreational lake and fishery. The closest residence, the only one within 1/4 mile of the site, is approximately 300 feet northeast of the Ward Transformer property. The site is being proposed to the NPL because elevated levels of polychlorinated biphenyls (PCBs), dioxins, furans, arsenic, chromium, copper, lead, manganese, and zinc, all attributable to facility operations, have been found throughout the site, and elevated concentrations of PCBs have been detected in surface water downstream of the site, posing a threat to recreational fisheries and wetlands.
Prior to 1972, storm water runoff flow from the facility was uncontrolled. Two impoundments were constructed around 1972 to collect runoff, and in 1979, a retaining wall (curb height) was constructed around the facility to direct runoff into the impoundment. An onsite treatment plant, installed in 1979, removes PCBs from the impoundment water prior to its discharge. More...
