The Ohio River Park site consists of approximately 32 acres on the western end of Neville Island, approximately 10 miles downstream of the City of Pittsburgh. The Ohio River borders the site to the north and the Back Channel of the Ohio River borders it to the south. The site is accessible from the mainland via the new Coraoplis Bridge, linking the Town of Coraopolis with Neville Island. Land use on Neville Island is generally industrial/commercial, although there are some residential areas. The middle section of the island is mostly residential and commercial while the eastern end of the island is heavily industrialized. Most of Neville Island's 930 residents live in the area between the Coraopolis bridge and Highway I-79. The nearest residence is located approximately 450 feet from the site. The eastern end of the island, approximately 2 miles east of the site, is occupied by petrochemical facilities, coal coking facilities, and abandoned steel facilities.
Prior to the 1940s, the predominant land use at the site was agricultural. Beginning in the mid-1930s until the mid-1950s, a portion of the site was used for municipal landfill operations including the disposal of domestic trash and construction debris. Industrial waste disposal activities were conducted at the site from 1952 through the 1960s. Much of the industrial waste was disposed of in two ways; wet wastes were placed into trenches and dry wastes were piled on the surface. In 1977, Neville Land Company donated the site area to Allegheny County. Allegheny County began construction of a park on the site and completed construction in 1979. The park was never opened to the public because approximately 13,000 cubic yards of wastes were discovered at the site during construction. The park was subsequently dismantled and the land was transferred back to Neville Land Company.
The Ohio River Park site was placed on the National Priorities List (NPL) in 1990. An investigation into the type and extent of contamination at the site was completed in early 1995.
|Remedy:||The remedy for controlling the buried waste and contaminated soils at the site is comprised of the following: capping of concentrated waste areas with a multilayer cap; capping areas not covered with the multilayer cap and not covered with adequate vegetative cover with an erosion cap; installing a surface water control system to control transport of surface soil both on and off site; abandoning the existing on-site oil well; installing a passive gas collection system to ensure the integrity of the cap; deed restrictions preventing residential use of the site; and long-term monitoring of groundwater, surface water, and sediment.|
