  • 99% of Oil from Leaking tanks remediated - Case study

    Spills and leaks from domestic and commercial oil tanks are a very common occurrence, caused either by the refilling of tanks or as the result of leaks. Very  often old metal tanks corrode and start leaking oil onto the ground around the tank. Also the tanks themselves become covered in dried hydrocarbons and become significantly discoloured, even black. Spilled oil can seep into the ground, ...

  • Per-and Polyfluoroalkyl Substances (PFAS) – An Emerging Challenge

    Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a large group of chemicals that were used for decades in numerous industrial applications (e.g., fire-fighting and metal plating foams, aviation hydraulic fluid) and consumer goods (e.g., stain repellent for clothes, furniture and carpets, and non-stick coatings). Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), both ...

  • Case study - Hydraulic slurry emplacement of potassium permanganate and zero valent iron for integrated site remediation

    Site Description: An active electronic manufacturing facility had an on-site TCE handling unit that was active for 10 years. During this time, approximately 1,365 gallons of solvent was released, which created an approximate 16 acre plume in saprolite and bedrock. Contaminants: Primarily TCE at concentrations greater than 200,000 ug/L in the source area with ...

  • Case study - Dual-reagent ISCO “Fast-Tracks” cleanup of Orlando Brownfield

    Description: A Brownfield property impacted with chlorinated solvents was the planned location for the home of the Orlando Magic basketball team. Contaminants: Chlorinated solvent contamination was present in soil and groundwater with PCE concentrations greater than 14,000 ug/L and potential presence of DNAPL. Remedial challenge: The ...

  • Thermally activated persulfate oxidation of NAPL chlorinated organic compounds: effect of soil composition on oxidant demand in different soil-persulfate systems

    This study investigates the interaction of persulfate with soil components and chlorinated volatile organic compounds (CVOCs), using thermally activated persulfate oxidation in three soil types: high sand content; high clay content; and paddy field soil. The effect of soil composition on the available oxidant demand and CVOC removal rate was evaluated. Results suggest that the treatment ...
