The 32-acre Ohio River Park Superfund Site is located on Neville Island in Allegheny County, Pennsylvania. A municipal waste landfill for Neville Township operated at the site from the 1930s until the mid-1950s. Industrial waste disposal activities continued at the site from 1952 through the 1960s. In 1978, Allegheny County began developing the site as a park, but stopped construction after discovery of industrial waste. Waste disposal practices contaminated soil and groundwater with hazardous chemicals. EPA investigated contamination at the site and it was listed on the National Priorities List (NPL) for clean up on August 30, 1990. EPA implemented cleanup remedies to address soil, buried waste, and groundwater. Following cleanup, operation and maintenance activities are ongoing.

What Has Been Done to Clean Up the Site?

The site is being addressed through Potentially Responsible Party (PRP) actions.

The remedy for the site is contained in three Records of Decision (ROD) issued in March 1993 (OU2), September 1996 (OU1), and September 1998 (OU3). The selected remedy addressed the following operable units (OU):

• OU1: Soil and Buried Waste

• OU2: Coraopolis Bridge Soil

• OU3: Site-wide Groundwater

The selected remedy for OU2 of "No Action" for Coraopolis Bridge soil did not require implementation of any remedial action.

The long-term remedy for site-wide soil contamination and buried waste (OU1) included installation of a multi-layer cap over an 11-acre waste disposal area, installation of a soil cap over the rest of the site, passive vents and institutional controls.

Following construction of remedial cap components on the site, Neville Land Company (NLC) began redevelopment activities at the site, opening the Island Sports Center in 1998.

The site achieved the “construction complete” Superfund milestone in September 1999. Operation and maintenance activities are ongoing.

The selected remedy for site-wide groundwater (OU3) included Monitored Natural Attenuation, which began in January 2014 and is ongoing. In addition, institutional controls are in place prohibiting residential development and groundwater use at the site.

In 2003, Robert Morris University (RMU) purchased the properties that make up the site to expand their athletic facilities. RMU has expanded the offerings of the Island Sports Center and has continued to maintain public use of the facilities and programs. Today, the site is home to a 5-acre building housing two indoor ice skating rinks, outdoor inline/ice rink facilities, a golf dome and golf training facility, a running track with center field space, a shot-put training area, sports equipment shops, dining facilities, paved parking areas and a mini-golf course.

What Is the Current Site Status?

The site achieved the “construction complete” Superfund milestone in September 1999. Operation and maintenance activities are ongoing. EPA continues to conduct Five-Year Reviews of the site’s remedy. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended. The most recent review, conducted in 2018, concluded that response actions at the site are protective of human health and the environment.
