  • Important things to consider when you have to treat dewatering discharge water at your site

    In many cases when you have to dewater an area of a construction or remediation site to do an excavation or other subsurface work, the water is clean and can be easily discharged without treatment. However, in some cases the soil and groundwater are contaminated, and if dewatering is required, it is highly likely that the discharge water will be contaminated and will require some type ...

  • Raynesway resource park - Case Study

    The Raynesway Resource Park is a 35 hectare site bounded on three sides by the River Derwent. The southern half of a former chemicals plant, soils and groundwaters were impacted by chlorinated solvents, acid tars, hydrocarbons and ammoniacal sludges. Celtic designed a sophisticated groundwater treatment system, integrating air sparging, multi-phase extraction and chemical oxidation to address ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Horizontal Well Rehabilitation at NASA Facility

    A horizontal groundwater extraction well at an active NASA facility in Louisiana was impacted by mineral scaling and bio-fouling affecting operations of the groundwater pump and the treatment system. A flow reduction of over 50% was observed. Directional Technologies, Inc. performed a series of horizontal well rehabilitation activities, that increases flow by 58%, which including mechanical ...

  • Ivey-sol • SPT DNAPL - Case Study

    Ivey-sol • SPT Technology was successfully used to remediation of a commercial dry-cleaning facility. The subject facility had been in operational since ca. 1971. The DNAPL contamination was comprised of DCE (Dichloroethylene) and TCE (Trichloroethylene) dry-cleaning solvents. Some minor Brominated compounds were also detected. The impacts were limited to the soil and groundwater under the ...

  • Texas Superfund Case Study

    The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a dissolved-phase benzene ...

  • TerraTherm to Remediate Soils at the Beede Waste Oil Superfund Site - Case Study

    The Beede Site is the former location of a state-licensed and regulated waste oil recycling and disposal facility. The nearly 41-acre Site is located in a residential area of Plaistow, New Hampshire (NH). Operations at the Site began in the 1920s, and continued until the state of NH ordered its closure in 1994. From the 1920s to 1994, thousands of NH residents and businesses were customers of the ...

  • Organic micropollutant removal from groundwater: comparison of pellet softening and nanofiltration

    This study investigated the fate of selected pharmaceuticals and estrogens and the characteristics of bulk organic matter during pellet softening and proposed a possible hybridization with nanofiltration (NF) treatment. A groundwater softening system called pellet softening was used to remove calcium ions from groundwater by crystallizing calcium carbonate on the surface of sand grains that ...

  • World War II Memorial, DC - Case Study

    In 2003, AdEdge Water Technologies began working closely with EarthTech, the assigned engineering firm responsible for specifying and selecting the various water treatment systems serving the new National World War II Monument in Washington, DC. Stormwater and groundwater control and treatment are essential aspects of this project given the location of the site on the Mall adjacent to the ...

  • Modeling of an immobilized sludge reactor with polyethylene glycol (PEG)-pellet to remove NH4-N from groundwater

    An immobilized sludge system model was developed to simulate nitrification (NH4-N → NO3-N) and denitrification (NO3-N → N2) processes in a PEG-pellet (microorganisms entrapped in polyethylene glycol (PEG)) reactor for removing NH4-N from groundwater. The nitrification and denitrification processes were described by modifying the Michaelis-Menten kinetic incorporating the factors of dissolved ...
