Chisman Creek
York County, Virginia

BEFORE
Soil, groundwater, and surface water contaminated by disposal of fly ash

AFTER
Chisman Creek and Wolf Trap Parks, softball and soccer fields, and a memorial tree grove

IMPACT
Improved landscape, recreational activities, protection of the ecosystem, increased income and residential property value

The field lights illuminate the evening. The bases are loaded. Fans cheer the batter. Sitting in the bleachers, you would never know that the field was once part of the Chisman Creek Superfund site. Today, the "keep out" signs are gone and the former fly ash disposal area supports two recreational parks with softball and soccer fields. Now, the familiar shouts and cheers of the games sound sweeter than usual because of the cleanup and redevelopment of the site. What follows is the story of how the partnerships formed by EPA made the site's transformation possible, and the economic impacts and environmental and social benefits that resulted.

Site Snapshot

Between 1957 and 1974, a local contractor deposited more than 500,000 tons of fly ash from Virginia Power's Yorktown Power Station in abandoned sand and gravel pits on the Chisman Creek property. Fly ash is a soot-like by-product that results from burning fossil fuels, such as coal and petroleum coke. In 1980, complaints from local citizens about discolored well water prompted state agencies to investigate the area. Results of the sampling showed heavy metal contamination in Chisman Creek, in the groundwater under the disposal areas, and in various on-site ponds. The metals included nickel, vanadium, arsenic, beryllium, chromium, copper, molybdenum, and selenium. The Chisman Creek site is 15 miles north of Norfolk, Virginia, and consists of three parcels of land covering 27 acres. Over 1,200 households are within two miles of the site. Chisman Creek, a tributary of the Chesapeake Bay, is a 4,200-acre coastal watershed that starts as a small stream and ends as a broad tidal estuary. The estuary, on-site ponds, and land were used by local residents for recreational purposes.

From Fly Ash...

In 1983, EPA added the site to its list of hazardous waste sites needing cleanup. Working with the local community, state agencies, and Virginia Power, EPA developed a two-part cleanup strategy. In 1986, Virginia Power began the first part of the cleanup which targeted the fly ash pits and contaminated groundwater. It extended public water lines to 55 homes with contaminated well water; covered the fly ash pits with clay, clean soil, and vegetation; and installed a groundwater treatment system at the oldest and deepest pit to collect and treat water trickling through the cap. To prevent use of the groundwater, Virginia Power filed deed restrictions with the county. The second part of the cleanup plan targeted the three on-site ponds, a freshwater tributary stream, and the Chisman Creek estuary. Virginia Power relocated a 600-foot portion of the tributary to lessen the possibility of contact with the fly ash disposal areas and protect the aquatic ecosystem. Finally, it established a program to monitor ground- and surface water quality for the ponds, the tributary, and the estuary.

...To Fly Balls

In 1986, a 12-member Stewardship Committee comprising local residents and business representatives, a geology professor from the nearby College of William and Mary, a NASA scientist, and environmental professionals was formed to oversee cleanup and redevelopment of the site. Local residents were eager for the cleanup, but wanted to continue to use the area for recreation. A sports park was the perfect solution. As part of the cleanup, Virginia Power built a site cap that would also serve as the foundation for playing fields, and leveled and graded the site, so York County could build park structures and sod the fields. York County also purchased a lighting system that was installed by Virginia Power during the final stages of the cleanup. The Chisman Creek sports park opened on May 4, 1991, with about 300 local residents, media, Virginia Power officials, and EPA, state, and county personnel on hand to enjoy the festivities. The 13-acre park has two lighted softball fields, restrooms, and a parking lot. The second park-the 28-acre Wolf Trap Park-features four soccer fields, restrooms, a parking lot, two ponds, and the County's Memorial Tree Grove.

Keys to Success

A spirit of cooperation and several partnerships were the key to the cleanup and redevelopment of the Chisman Creek site. EPA coordinated with state and federal agencies to complete sampling, and health and ecological assessments at the site. The Stewardship Committee created a powerful forum for interested people and organizations to provide input on cleanup and redevelopment decisions and hear about progress. EPA, York County, and Virginia Power together coordinated the cleanup and redevelopment. This partnership's efforts earned an Environmental Achievement Award from the National Environmental Awards Council. The Consulting Engineers Council of Pennsylvania also recognized the engineering firm that designed the drainage system, clay cap, and recreational facilities with the council's "Grand Conceptor" award.
