  • Enhanced Bio-Stimulation through Horizontal Wells

    Biosparging technology can be further enhanced when applied through Horizontal Remediation Wells. Since horizontal well systems typically have 4 to 10 times more screen footage in contact with the contaminated media than vertical systems, Horizontal Biosparge Wells can inject much greater volumes while maintaining the same low flow rates. This, in turn, leads to more rapid increases in dissolved ...

  • Green remediation

    The US Environmental Protection Agency’s (EPA) strategic plan calls for increased research and application of sustainable systems that promote environmental stewardship, reduce greenhouse gas (GHG) emissions, and improve energy efficiency. One area of this research is green remediation. Green remediation is a relatively new approach to environmental cleanup; expanded from the traditional ...


  • The Effectiveness of Using Automated Belt Oil Skimmers as a Method of Well Remediation

     ABSTRACT In many sites across the country, groundwater has been contaminated by petroleum products due to leaky underground tanks or past spills. If the leak has gone unnoticed, a considerable amount of product could exist in an aquifer (underground water reservoir), and may be trapped in the surrounding rock. Remediation can take months or years to complete and is frequently labor ...

  • Port of antwerp oil spill soil remediation project case study

    THE PROBLEM In 1990, 4500 m3 of silty sand/soil contaminated with mineral oil (diesel) to a level of 1500 ppm was treated on-site (Port of Antwerp) at the request of the client. OUR APPROACH On reviewing both the site and the scope of the project it was clear to Nordevco staff that the most cost effective and efficient approach would be to treat the soil in a ...

  • Remediation of hydrocarbon contaminants from oil lagoons and refinery waste - case study

    In 2007 econ delivered an indirectly heated thermal desorption plant to a client in Kuwait. The plant is de-signed to treat various types of waste with hydrocarbon contaminant content. In particular refinery waste, oil lagoons and down hole drilling waste. The aim is to recover the waste hydrocarbons from the soil/sand and remediate the lagoons of their contaminants.  Due to the natural ...

  • 93% of Oil from Railway tracks remediated - Case study

    Railway engines are predominantly diesel and as such  they discharge large volumes of oil, diesel and hydraulic fluids as they operate. These hydrocarbons contaminate the railway lines, stations and sidings on which the engines operate. For many years the hydrocarbon discharges have been ignored, with the tracks and surrounding lands becoming heaving contaminated. However, new ...

  • Nanobite remediates boyne river oil spill - Case study

    On the 6 September 2007, an oil spill from a fuel dump leaks into the beautiful Boyne River, County Louth, Ireland. Local wild fowl and their nesting areas are endangered, as is the local water supply. The coastguards deploy conventional booms to contain the spill but decide against the use of conventional chemical detergents because of the obvious damage to flora and fauna. ...

  • 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, ...

  • Remediation contracting, Northern England

    Project Remediation Strategies were requested to attend a redevelopment site in North-West England to supervise excavation works in an area of known hydrocarbon contamination and to assist the developer in the short term recovery of hydrocarbons. Workscope A Response Team was mobilised to site with a mobile oil-water separator, pumps, pipework and an oil ...

  • Learn why All Zero-Valent Iron (ZVI) Remediation Products are not the same

    The MAJOR DIFFERENCE between Emulsified Zero-Valent Iron (eZVI) and other ZVI products is the physical structure of the eZVI product, which is a water-in-oil emulsion (see below images). This structure makes the eZVI product hydrophobic, and therefore it is fully miscible with source material in situ. The water contained in the interior of the eZVI emulsion provides the hydrogen for abiotic ...

  • Remediation of Abandoned Coal Mines Using Coal Combustion Products

    A slurry of mine water and coal combustion fluidized bed ash (FBA) was injected into an abandoned coal mine in Eastern Oklahoma in July 1997. Oil-field technology was used to inject 1.8 Gg (418 tons) of FBA through five wells in 15 hours. Alkaline minerals in the FBA neutralized acidity and imparted alkalinity to the mine water. Thus, this remediation method uses the waste from an industrial ...


  • Impact of heavy metals on the oil products biodegradation process

    Oil products continue to be used as a principal source of energy. Wide-scale production, transport, global use and disposal of petroleum have made them major contaminants in prevalence and quantity in the environment. In accidental spills, actions are taken to remove or remediate or recover the contaminants immediately, especially if they occur in environmentally sensitive areas, for example, in ...

  • 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 ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • ST. Thomas, USVI diesel oil spill soil remediation project case study

    The Problem Staff at a major four-star resort outside St. Thomas in the US Virgin Islands spilled diesel fuel and kerosene during the transfer from a tanker truck to on-site storage tanks. Approximately 67.3 m3 of soil having an average concentration of 12,000 ppm was contaminated. Because there are no treatment facilities on the Island, the resort was facing significant costs to transport ...
