  • Case study - California vineyard improves sludge movement with aeration

    Overview A California vineyard was faced with the challenge of meeting wastewater treatmentcompliance under a tight deadline defined by local regulators, while receiving ongoingodor complaints from the community. Challenges Extended periods of mismanagement from previous owners left the facility and the wastewater treatment system in disarray. ...

  • Groundwater Remediation

    Groundwater remediation or clean-up is required when concentrations of contaminants exceed or are expected to exceed predetermined levels for the type of resource that is impacted (Grossman et.al., 2008). For example, lead levels in drinking water should not exceed the EPA action level of 0.015 mg/L. What caused the high levels of lead? How can the lead be removed from the aquifer? (Grossman ...

  • Sustainable remediation

    The term remediation refers to procedures implemented to eliminate contaminants and toxic waste from polluted landfills, water bodies and other places to promote environmental health and safety. Since its inception in the 1970s, remediation itself has evolved into a full-fledged industry. Organizations engaged in environmental construction activities typically execute remediation projects. In ...

  • A 10-year prospective on remediation

    For the last thirty years we have all been working very hard to put ourselves out of the remediation business, so why be concerned with where  remediation will be ten years in the future? In responding to environmental legacies of the past hasn’t industry put policies and procedures in place to prevent the creatin of future liabilities? Don’t we design and operate facilities today to minimize the ...

  • Tackling remediation emissions

    Organisations commissioning regeneration projects now have the option to substantially reduce the carbon emissions associated with any remediation project, while offsetting the remaining carbon impact of these works, says Joe Teer, operations director of QDS. QDS introduced a carbon neutral remediation (CNR) service earlier this year triggered at this particular time by the fact ...

  • 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 ...

  • An Assessment of Environmental Concerns in the Leather Industry and Proposed Remedies: a Case Study of Pakistan

    In the leather sector different types of finished leather is prepared from salted raw skins. There are about 596 tanneries in Pakistan in the formal sector and more than 90% of their product is exported. About 130 different types of chemicals are used in leather manufacturing which ranges from common salt (Sodium Chloride) to very expensive Chrome Sulphate. The chrome tanning process is widely ...


  • Remediation of mercury contaminated industrial site for future expansion - case study

    70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry® 12,000 has been in operation since early 2011. After the treatment the mercury free soils can be re-used on-site as building material. A similar but smaller econ industries ...

  • Cement industries solution to Waste Management - Remediation of oil refinery sludge basin

    Abstract Work was completed in early 1992 to clean up a 5.5 acre (2.2 ha) stormwater sludge basin for an oil refinery company. The basin, which had served as a stormwater collection and settling pond for over 40 years, contained oily sludges with high concentrations of certain metals and volatile organic compounds. The closure plan included a combination cement-bentonite slurry wall and jet ...

  • Sonic making inroads on PCB remediation?

    The Sydney Tar Ponds of Nova Scotia are the result of a century of coal mining and steelmaking, which left behind 900,000 tonnes of chemical waste. About 5 per cent or 45,000 tonnes of this waste is contaminated with high levels of PCBs. Two years ago a federal-provincial plan was announced to clean up the Tar Ponds over 10 years at a cost of $400 million, and this led to the creation of the ...


  • Mold Remediation Guidance For Indoor Environment

    Remediation contractors are generally very conscientious, trying hard to bring each project to a condition where it will pass “clearance  testing” (the  Post-Remediation  Verification  [PRV] inspection) on the first try. Sometimes the cleaning attempts are unsuccessful. This will certainly cost the contractor additional cleaning ...

  • Chloroflourocarbon (CFC) remediation case study

    Project Description The Site location was an industrial facility located in the greater South Los Angeles region that manufactured chemicals for local petrochemical and other industrial operations from 1919 through late 1990’s. Refrigerants were initially produced in 1964 including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) such as trichlorofluoromethane (R-11), ...

  • Remediation of DNT drum disposal area.

    In 1991, an abandoned drum disposal area was discovered in a small ravine known as the Wash 3 tributary at the Apache Powder Superfund Site near Benson, Arizona. The 110-gallon steel drums were found to have been used to store 2,4- and 2,6-dinitrotoluene (DNT) that was purchased for experimental formulation of a composite explosive for the mining industry in the 1955 to early 1960's timeframe. ...

  • TCE/Fractured Bedrock Remediation in VA

    Site Summary At a manufacturing facility HRC was injected into a crystalline bedrock aquifer contaminated with TCE and its daughter products. Groundwater flow at this site is controlled by fractures in the crystalline rock with little or no permeability present beyond these fractures. The industrial facility had been in operation for over 30 years. Contamination levels reached 220 ppb of TCE so ...

  • Important Facts About Saltwater Remediation

    Soil that has suffered erosion due to salt, generally becomes useless to any kind of vegetation. This soil becomes crusty and if a lot of acreage is involved, it can cause upsets in ecosystems as well. While researchers have found some ways to treat these areas, the time those processes took were long and tedious. Thanks to today's technology for ...
