Superfund Site: HANFORD 1100-AREA (USDOE), BENTON COUNTY, WA
Superfund Site Profile
The 120-square-mile Hanford 1100-Area (USDOE) site is located about one mile north of Richland, Washington. The site is one of the four areas listed on EPA’s National Priorities List (NPL) located within the larger U.S. Department of Energy (DOE)-managed Hanford Site. Waste areas at the 1100-Area site include a landfill, drains, underground tanks and a sand pit where as much as 15,000 gallons of waste battery fluids may have been disposed. Past site activities and waste disposal practices contaminated soil and groundwater with hazardous chemicals and heavy metals. Following cleanup, EPA took the site off the NPL in 1996.
