Groundwater remediation technologies to clean superfund site
The chemical contamination at the Spectron, Inc. Superfund site six miles north of Elkton, MD, isfinally getting cleaned up.
TerraTherm, Inc., has announced that it has beenawarded a $6.9 million contract to clean up the spill in Cecil County. Using its patented Thermal Conductive Heating (TCH) to heat the soil and shallow groundwater at the site to about 100 degrees Celsius, they will be able to remove the chemical from the subsurface and then use a thermal oxidiser to destroy the contamination.
These groundwater remediation technologies are commonly used at hazard waste sites such as the one in Elkton. In the U.S., around80% of such sites have negatively affected nearby groundwater, which is often used as a drinking water source for Americans.
Sites that are part of the Superfund are designated by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, which is a federal law that regulates the clean up of hazardous waste sites.
TerraTherm's process is expected to remove 99% of the contamination in the soil.
The site started out as a water-powered paper mill from the mid-1800s to 1946. Between 1962 and 1988, it was used as a recycling and treatment facility for electronic, pharmaceutical, paint, lacquer, coatings, and chemical recycling.
In 1994, the U.S. Environmental Protection Agency added the site to its National Priorities List, which names the most serious hazardous waste sites in the country.
