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.
240-acre future residential development; Confidential client
Ontario, Canada
DDT, DDE, Dieldrin
Approximately 34 acres of 240 acres of land had residual concentrations of organochlorinated pesticides that exceeded the residential use standards. Daramend® reagent was spread onto the soil and incorporated using specialized rotary tillers to drive the oxidation reduction potential (ORP) down.
For plots that were treated in one cycle, the average percentage removal ranged from 38% to 53% of DDT, DDE and Dieldrin. For plots that required two treatment cycles, the average percentage removal was between 65% and 68%. The remedial standards were met for 100% of the plots within a period of four months.
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® 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.
This project was designed to validate Daramend® applications on chlorinated pesticide impacted soil in Ontario, Canada.
