DARAMEND® treats soils containing chlorinated herbicides and pesticides, organic explosives and chlorinated VOCs (CVOCs) at many sites around the world. In our case studies, we show you how the DARAMEND® product family removes pollutants from soils through specific remediation projects.
With a total treatment period of 3 months, the application of DARAMEND® Reagent has reduced concentrations of PCE and TCE below remediation standards at this site in the northwestern United States.
DARAMEND® was first applied to a two-hectare pilot project and then to an additional 32 hectares. The treatment resulted in successful removal of concentrations of organochlorine contaminants in the soil within time and cost constraints.
DARAMEND® Reagent was the selected technology at a site for the treatment of 350 tons of soil impacted by phenoxy-acid herbicides (2,4-D, and 2,4,5-T), and other chlorinated pesticides (DDT, DDD, and DDE).
A 90-acre site formerly used as an oil waste disposal facility needed remediation before conversion to a 300-unit residential development and endangered plant refuge. This is because volatile organic compounds (VOCs), including 1,2-dichloroethane (1,2-DCA), cis-1,2-dichloroethene (cis-1,2-DCE), and vinyl chloride (VC) were contaminating soil and groundwater.
A 2,600-ton in situ pilot was conducted at a site in Florida using DARAMEND® Reagent achieving remedial goals within 3 weeks.
This soil remediation project was to validate DARAMEND® applications in soils in Ontario, Canada that are contaminated with chlorinated pesticides.
DARAMEND® Reagent was applied at pilot scale to approximately 100 tons of soil from the site, which was formerly used as a high explosives salvage and melt-out area from World War I through the 1920s.
DARAMEND® Reagent effectively reduced the concentrations of TNT, DNT and tetryl during two separate pilot-scale demonstrations on contaminated soil. DARAMEND® was also effectively applied during a full-scale (3,000 ton) demonstration of the technology at the same site on TNT impacted soil.
The Atlantic Division of the US Naval Facilities Engineering Command, in conjunction with the Yorktown Naval Weapons Station (WPNSTN) initiated the multi-batch, full-scale bioremediation of soil impacted with organic explosive compounds (OE) at the WPNSTN.
The army detected trinitrotoluene (TNT) and cyclomethylenetriamine (RDX) in soil near the TNT washout area (designated as SWMU-10), threatening the ground water for 2,500 people who depend on wells within 3 miles of the site.
