Superfund Site Profile
The New Castle Steel site is located near the Delaware River in New Castle, Delaware. The site consists of a three-acre landfill that received foundry wastes from the Deemer Steel Company from 1907 to 1987. In 1973, facility operators installed a baghouse system to control dust emissions from a furnace. Dust from the baghouse was mixed with black sand and spread over the disposal area from 1973 to 1980. This practice contaminated soil, groundwater, sediment and surface water with hazardous chemicals. Following a "No Action" Record of Decisin in 1988, EPA took the site off the Superfund program’s National Priorities List (NPL) in March 1989.
