  • 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 ...

  • A novel approach to remediating contaminated groundwater by reusing industrial co-products

    This paper presents a novel approach to remediating contaminated groundwater by utilising industrial co-products. The materials discussed include paper clay and steel slag, and the primary water contamination considered is heavy metal contamination. Paper clay was determined to have the potential for adsorbing heavy metals, and in compacted form could achieve permeability values within the ...

  • 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 ...


  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • 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 ...


  • Remediating groundwater contaminated with chlorinated solvents - a Canadian perspective

    Chlorinated solvent contamination of groundwater is a recognized barrier to both potable water use and brownfield site redevelopment in Canada. Several high-profile trichloroethene (TCE) contaminant issues such as those in Cambridge, Ontario, and in Shannon, Québec, have increased public awareness of this problem, and also stimulated the Canadian consulting community to consider the use of in ...


  • TCE Remediation at a Brownfield Site – St. Louis, MO

    Site Summary In June of 1999, the property owner of this former metal container manufacturing facility decided to redevelop theproperty into commercial office space. However, environmental assessment revealed impacted soil andgroundwater with TCE and 1,1,1-TCA, as well as their breakdown products (making it clear that some degree ofbioremediation was already occurring). Redevelopment ...

  • Consideration of the Effects of Remediation Technologies on Natural Attenuation.

    ABSTRACT: We have long understood and continue to improve our understanding of the geochemical conditions that favor biodegradation of petroleum hydrocarbons. Over the last several years our understanding of the conditions that are necessary for and/or promote reductive dechlorination of chlorinated hydrocarbons has improved substantially. Over this time in situ remediation technologies have ...

  • Superfund Remediation: The Key to Land Reuse Case Study

    The technology is ready and, with state and federal tax credits waiting, the economics look better than ever: New Jersey, one of the first states to be industrialized, finds itself plagued with the contaminated aftermath of pre-EPA industries: soil contamination. From superfund sites to the gas station whose underground storage tank has been oozing for the last 20 years, every ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...

  • Trace metal characterization of soils using the Optima 7300 DV ICP-OES

    Soil testing helps diagnose soil health and guides in the development of soilspecific and crop-specific remedies. It is an indispensable tool to assure national food safety, nutritional accuracy, maintenance of soil health and enhancement of soil fertility. Based on this analysis, farmers may be advised on soil fertility to make agriculture more productive and sustainable. Micronutrient analysis ...

  • 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 ...

  • Brownfield remediation - Urban revitalization requires local groups to learn to identify brownfield sites and understand the liability issues and environmental concerns.

    Brownfields are defined by the United States Environmental Protection Agency as 'abandoned, idled, or under-used industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination.' Vacant industrial sites, gas stations, commercial buildings, and offices all fall under the heading of brownfields. Brownfields can be found in almost ...


  • EFFECT OF CROPPING SYSTEMS ON HEAVY METAL DISTRIBUTION AND MERCURY FRACTIONATION IN THE WANSHAN MINING DISTRICT, CHINA: IMPLICATIONS FOR ENVIRONMENTAL MANAGEMENT

    We studied the concentration of heavy metals and mercury fractionation in contaminated soil for two agricultural land use systems (paddy rice and dry‐land) at the Wanshan Hg mine in China. The average concentration of chromium, lead, copper, nickel and zinc was generally lower in paddy‐rice (PR) soil relative to corn field (CF) soil. Soil under CF production was slightly contaminated with lead ...
