  • Case study - Ozone sparging closure of an industrial VOC spill site adjacent to a water supply well site

    Description An undocumented surface spill at an active manufacturing facility located adjacent to a public water supply well field released chlorinated volatile organic compounds (PCE, and its breakdown products: TCE, c-DCE, and VC) into soils and groundwater.  The driver for site cleanup was three water supply wells located 200 feet downgradient of the site bounds.  The chosen ...

  • Case study - Rapid removal of chloroethenes at industrial sites

    Description Air sparging with trenches had failed to remove groundwater and soil contamination at an industrial Superfund site in Piedmont soils in South Carolina.  The major contaminants of concern were cis 1,2-dichloroethene (DCE) and trichloroethene (TCE) ranging from 0.5 to 2.0 mg/L.  The treatment area was approximately 15,000 square feet. Ozone sparging was ...

  • The economic pre-treatment of coal mine drainage water with caustic and ozone

    Coal mine drainage waters are low in pH with varying amounts of iron and manganese and are generally brackish.
