  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Diesel and Gasoline Remediation in Groundwater and Soil at a DoD Site

    Site Summary Three above ground storage tanks (containing gasoline and diesel) and associated piping were removed from a DoD site in January 1990. Concentrations of TPHd and TPHg were found in soil samples collected around the former ASTs at concentrations of 140 mg/kg and 9,400 mg/kg, respectively.  Groundwater contamination was also detected with TPHd concentrations reaching 21,000 ug/L ...

  • Green remediation best management practices: site investigation

    Overview The need for site investigation is common to cleanups under any regulatory program. An investigation can occur at all points in the cleanup process, from initial site assessment through waste site closeout. A site investigation generally is undertaken to: Confirm the presence or absence of specific contaminants Delineate the nature and extent of environmental contamination ...

  • NJDEP issuing remedial priority scores for contaminated sites

    Very shortly, the New Jersey Department of Environmental Protection (NJDEP) will be issuing letters to responsible parties containing a draft Remedial Priority Score (RPS) for their particular site. It is unclear how the rankings will be used, but the RPS system has been described as a tool to sort sites out for further discussion. The ...

  • Air emissions impact measurements at a perchloroethene remediation site

    As part of an U.S. EPA time critical removal action, an air monitoring system was established to measure real-time impacts of perchloroethene (PCE) on the surrounding areas. The soils and groundwater beneath the site (located in West Fargo, North Dakota) were treated using in situ heating of soil and groundwater, with the produced vapors collected using conventional vapor extraction. In order ...

  • Case study - World`s largest remediation site

    Overview Hong Kong's Kai Tak Airport, the world's busiest airport in 1997, became the world's largest remediation site once it was closed. When the airport was decommissioned in 1999 in favor of the new Chek Lap Kok Airport, the government planned to rapidly clean up the site for commercial and residential development. After many years of soil penetration by various ...

  • Modeling Leachate Contamination and Remediation of Groundwater at a Landfill Site

    Leachate contamination of an aquifer from a landfill sitewas simulated using the groundwater flow and transport model SUTRA developed by the U.S. Geological Survey. The model calibration was performed by spatially adjusting the hydraulic conductivity in order to capture the measured hydraulic head spatial variation and then by adjusting the dispersivity and porosity match the measured chloride ...
