  • USACE integrates fracturing and iron/carbon injections at Colorado site

    The U.S. Army Corps of Engineers (USACE) performed a large-scale pilot test in 2009 for remediating TCE-contaminated groundwater at the "Atlas 12" formerly used defense site. Hydraulic fracturing was conducted to optimize emplacement of a zero-valent micro-iron/complex carbon amendment that chemically and biologically reduces contaminants in bedrock. Three-dimensional (3-D) mapping was used to ...


  • TROLL 9500 Used In Combined Remedy Approach at Former Dry Cleaning Site Contaminated with PCE

    A former dry-cleaning site in the Pacific Northwest, Ultra Custom Care Cleaners, was found to be contaminated with PCE (perchloroethylene). According to the U.S. Geological Survey (USGS), PCE was widely used in the dry cleaning of fabrics since the 1940s.  PCE is one of the most frequently detected VOCs (volatile organic carbons) in groundwater at a national scale (Moran 2004). PCE is highly ...

  • Triad use at naval base San Diego saves an estimated six years and US$3m for site investigation

    The U.S. Naval Facilities Engineering Command Southwest (NAVFAC SW) used the Triad approach to collect an integrated hydrogeologic and chemical dataset for expediting and optimizing characterization of a volatile organic compound (VOC) plume at Naval Base San Diego (NBSD), CA. The 295-acre 'IR Site 22' was identified in 2003 when VOC concentrations reaching 100 mg/L were reported in an upgradient ...

  • Clean-up of dense nonaqueous-phase liquids (DNAPLs) at US hazardous waste sites

    The US EPA's Office of Superfund Remediation and Technology Innovation has constructed a website that compiles available information related to the cleanup of dense nonaqueous-phase liquids (DNAPLs) at hazardous waste sites. This initial phase addresses the most common DNAPL contaminants: chlorinated ethenes (e.g., tetrachloroethene and trichloroethene) and multi-component wastes (creosotes, ...
