• EHC® Metals Injection for Lead Treatment at a Former Battery Recycling Facility in Brazil

  EHC Metals Reagent is now a part of the MetaFix portfolio of customizable reagents. EHC Metals Reagent has been shown to effectively immobilize lead (Pb) from groundwater at a former battery recycling facility in Brazil.

  MetaFix® Reagents Heavy Metals

• MetaFix® PRB Prevents Migration of Heavy Metals into an Adjacent River and Exceeds Remedial Goals

  The main contaminant of concern, aluminum, has decreased from a baseline concentration of 1,530 μg/L to 224 μg/L after ten months, which is well below the remedial goal of 750 μg/L. Significant reductions also have been observed in dissolved arsenic and copper downgradient from the PRB.

  MetaFix® Reagents Heavy Metals

• Remediation of a Historic Chrome Residue Stockpile Site to Below Remedial Goals

  An initial treatability test followed by field application demonstrated that a low dose of MetaFix was successful in treating soils highly contaminated with chromium to below a stringent remedial goal of <1 mg/kg.

  MetaFix® Reagents Heavy Metals

• Reduction of PCE and TCE Concentrations in Soil to Below Remedial Standards

  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 Chlorinated Solvents

• Remediation of DDT, DDE and Dieldrin on a 240-acre Future Residential Development Site using Daramend® Reagent

  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 Pesticides & Herbicides

• Daramend® Reagent for the Treatment of Herbicides and Pesticides at a Confidential Chemical Facility in Ontario, California

  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).

  Daramend® Reagent Pesticides & Herbicides

• Elimination of Potential Vapor Pathway and Remediation of VOCs by using a Daramend®-sand mixture

  With nine years of data Daramend® addressed long-term mitigation of vapor pathway concerns over exposed areas containing concentrations of dissolved VOCs.

  Daramend® Reagent Chlorinated Solvents

• Treatment of Organochlorine Pesticides from Impacted Soils using Daramend® Reagent

  A 2,600-ton in situ pilot was conducted at a site in Florida using Daramend® Reagent achieving remedial goals within 3 weeks.

  Daramend® Reagent Pesticides & Herbicides

• Daramend® Reagent Used to Treat Soil Impacted by Chlorinated Pesticides

  This project was designed to validate Daramend® applications on chlorinated pesticide impacted soil in Ontario, Canada.

  Daramend® Reagent Pesticides & Herbicides

• Remediation of TNT & DNT in Homogenized Soil by using Daramend® Reagent

  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.
