Both superfund and brownfield sites are efforts that seek
productive uses for environmentally impaired properties. Although they both
intend to find alternative uses for destroyed or harmed land, each program
addresses a different kind of site and use different methods to accomplish
their goals. Superfund is the federal government’s program to clean up the
nation’s uncontrolled hazardous waste sites, while Brownfields are properties
that are abandoned or underutilized because of actual or perceived
contamination to the environment. There are over fifteen superfund sites in Georgia.
Examples of Georgian Superfund sites include:
Robins Air Force
Base:
Robins Air Force Base is located less than twenty miles
south of Macon. In the 1960s and 1970s one of the landfills became the disposal
site for several solid and hazardous wastes, including industrial sludge,
solvents, and oils. This site posed threats to the environment and to residents
on the base because the groundwater and soil became contaminated
with harmful chemicals. The toxic portion of the landfill was decommissioned in
1978. Cleanup of the waste pit began in 1991 and was completed by
1998.
Brunswick Wood Preserving:
The Brunswick Wood Preserving is located in Glynn County. Poor waste
management, accidental spills, and open dumping resulted in extensive
groundwater and soil contamination at the site in 1996. The EPA attempted to
clean the site by a method known as “capping” in which they covered the
affected soil with layers of gravel, clay and even more soil to keep rainwater
from leaching harmful chemicals into the surrounding groundwater. Despite their
efforts, surrounding shallow groundwater and soil, as well as a nearby creek,
remain contaminated.
Diamond Shamrock
Corporation:
The Diamond Shamrock Corporation’s landfill is located in
Polk County. The site contained about 900 drums of hazardous products. In 1980
the company reported its hazardous waste to the EPD. Potential contaminants
from the site included manganese and several volatile organic compounds. Cleanup
of the site concluded in 1990; however, the EPA conducts reviews at the site
every five years to make sure that it is no longer a threat.
Firestone Tire and
Rubber Company:
The Firestone Tire and Rubber Company is located in Dougherty
County, GA. Until 1980, drums of waste cement were stored on the ground in an
area of less than 1 acre. In another area, waste was buried in a pit during
fire-training exercises. An estimated 400 people obtain drinking water
from private wells within 3 miles of the site, and 1,000 acres of cropland are
irrigated with well water. A consultant to the company detected Benzene, 1,
1-Dichloroethylene, Toluene, 1,1-Dichloroethenane, 1,1,1-Trichlorothenane,
and zinc in on-site wells. Fortunately drinking water wells are not
potentially threatened.
