This project was designed to validate Daramend® applications on chlorinated pesticide impacted soil in Ontario, Canada.
Ontario, Canada
Metolachlor
A treatment cell was divided into three separate areas, which included a 230-ton main treatment cell and two 10-ton treatment cells. One contained heavily impacted soil, and the other contained soil similar to the main treatment area for use as an untreated control. Daramend® reagent was applied to reduce the concentration of Metolachlor in the soil.
Following 10 months of active treatment, the mean concentration of Metolachlor was reduced to <1mg/kg in the main treatment cell and 11mg/kg in the heavily impacted treatment cell. Concentration remained unchanged in the control cell.
With a total treatment time of 3 months, the application of Daramend reagent reduced concentrations of PCE and TCE below the remedial standards at this site in the northwest USA.
Daramend® was applied first to a two-acre pilot project, and then to an additional 32 acres. The treatment successfully destroyed the concentrations of organochlorinated contaminants on time and on budget.
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).
With nine years of data Daramend® addressed long-term mitigation of vapor pathway concerns over exposed areas containing concentrations of dissolved VOCs.
A 2,600-ton in situ pilot was conducted at a site in Florida using Daramend® Reagent achieving remedial goals within 3 weeks.
