The NRAP site is a state-lead site in its 7th year of groundwater treatment operations by in-situ enhanced reductive dechlorination. The site’s lead agency, the New Mexico Environment Department (NMED), recently completed a response action report to document ongoing progress in their remediation efforts. NMED utilized EnviroInsite in that effort to assist in the interpretation of sampling results.
Enforcement of Superfund Liabilities Expands Beyond Environmental Avenues
A recent Superfund-related case in New Jersey highlights how US authorities, both Federal and State, will not take kindly to companies that seek to circumvent their environmental responsibilities. Companies, and their subsidiaries, that are landowners or waste generators, who are responsible for contaminating a Superfund site should ensure they are in compliance with requirements to clean up the site, reimburse the government, or reimburse other parties for cleanup activities. The New Jersey House of Assembly...

Case study - Rapid removal of chloroethenes at industrial sites
Description Air sparging with trenches had failed to remove groundwater and soil contamination at an industrial Superfund site in Piedmont soils in South Carolina. The major contaminants of concern were cis 1,2-dichloroethene (DCE) and trichloroethene (TCE) ranging from 0.5 to 2.0 mg/L. The treatment area was approximately 15,000 square feet. Ozone sparging was chosen as preferred remediation alternative for several reasons. Ozone rapidly reduces common organic contaminants such as chlorinated VOCs and BTEX....
E-Z Trays selected for Large scale project - Case Study
A former industrial plant and top Superfund site in Sydney, Australia, had been in operation since the 1930s and contained chlorinated solvent contamination. Because of the size and scope of this project packed towers traditionally would have been the air stripping method of choice, but the client was concerned about the ability of workers having easy access to maintain and clean the units. They also wanted to lower the process water pH to 2.5-2.0 in order to keep fouling from occurring. Additional problems...
E-Z Trays® Treating Multiple Groundwater Contaminants in Grand Island, NE - Case Study
The U.S. Environmental Protection Agency has launched an effort to treat contaminated groundwater in Grand Island, Nebraska. The Parkview Well Superfund Site consists of two areas of groundwater contamination, the Northern and Southern Plumes, which include several volatile organic contaminants including tetrachloroethene (PCE), 1,1-dichloroethene (DCE), 1,1,1-trichloroethane (1,1,1-TCA) and 1,1-dichloroethane (1,1-DCA), and 1,4-Dioxane.In 2010, the construction of a groundwater extraction well network and...
