About the Superfund Redevelopment Initiative
This nationally coordinated effort provides EPA and its partners with a process to return Superfund sites to productive use. Learn more at Superfund Redevelopment Initiative.
Redevelopment at the Site
The Aerojet General Corp. Superfund site covers about 5,900 acres near Rancho Cordova, 15 miles east of Sacramento, California. Since 1953, Aerojet and its subsidiaries have researched, designed and manufactured rocket engines and formulated chemicals on site. Disposal and operating practices led to soil and groundwater contamination. EPA listed the site on the Superfund program’s National Priorities List (NPL) in 1983. Since then, Aerojet has worked to contain and address contaminated groundwater using multiple groundwater pump-and-treat systems. Aerojet is also investigating how to further prevent the spread of contaminants and to more fully clean up of soil and groundwater contamination sources. In 2008, Aerojet started plans to convert a portion of its facility into a solar farm to help power the site’s extensive groundwater cleanup program. Aerojet viewed this as an opportunity to reduce the company’s carbon footprint and improve energy use. Installed in 2009 and 2010, 22 solar arrays now generate 6 megawatts of power. The electricity produced provides more than 20 percent of the energy needed to power the site’s groundwater cleanup program. Aerojet continues to operate on the site. Tenants also use the site for a variety of office, commercial and light industrial activities. Aerojet has begun the planning process to reuse portions of the site. Reuse will include a mixed-use development with residential, commercial and industrial uses.
Economic Activity at the Site
As of December 2018, EPA had data on 7 on-site businesses. These businesses employed 2,404 people and generated an estimated $1,364,323,852 in annual sales revenue. View additional information about redevelopment economics at Superfund sites.
