  • Case study - Groundwater remediation of a contaminated site using enhanced anaerobic bioremediation

    Chlorinated solvents are a common threat to drinking water sources throughout the United States. While handling and disposal practices today are more closely regulated and monitored, this has not always been the case. With dry cleaners using tetrachloroethene (PCE) and industrial manufacturing facilities commonly using a variety of solvents from trichloroethene (TCE) to methylene chloride, past ...

  • Waterloo Emitters used for Bioremediation Study in High Temperature Saline Groundwater

    A study was undertaken to determine the success for aerobic bioremediation of aromatic hydrocarbons (BTEX) and MTBE (methyl tert-butyl ether) in high temperature, saline groundwater conditions. The study included laboratory microcosm experiments, as well as a field trial in Saudi Arabia, in which Solinst Waterloo ...

  • Operating conditions for the continuous bioremediation of free cyanide contaminated wastewater using Aspergillus awamori

    Generation of cyanide-containing wastewater is a growing problem worldwide as numerous cyanide complexes are highly unstable and degrade to form free cyanide (F-CN), the most toxic form of cyanide. Agro-waste materials, such as sweet orange (Citrus sinensis) waste from the citrus industry, are rich in readily metabolisable carbohydrates that can supplement microbial activity and thus support ...

  • Outstanding bioremediation in winter months case study

    Alga Power 101 was again able to prove its efficacy when it was utilized on a former industrial site in West Thurrock, Essex, under some extremely challenging conditions. Formerly a scrapyard, the contaminated site was heavily laden with diesel and other fuels. Prior to treatment the TPH of the soil ranged between 8,000mg/kg and 10,000mg/kg. Bioremediation took place between November and December ...

  • Bioremediation of Kerosene and Diesel Fuel in soil case study

    The United States has a large hazardous waste problem that is threatening both human health and the environment. Current analysis of the nearly 1,200 National Priority List (NPL) sites reveals that about 80% of the sites are contaminated with organic compounds. Clean-up of hazardous waste sites, as a national priority has accelerated the development of bioremediation technologies. Environmental ...

  • Bioremedation and TPH analysis at Lumwana Copper Mine in Zambia

    MINING SITE: Equinox Minerals operates the biggest copper mine in Africa located at Lumwana in Northwest province Zambia.  Open pit mining methods are used to access the ore which is hauled to the process plant where it is crushed and processed into final concentrate. The mine operates a large fleet of equipment, including 27 EH4500 dump trucks, 5 shovels, 4 excavators ...

  • Tyco earth tech - soil bioremediation

    Summary: In June 2006 EarthTech (a member of the Tyco group of companies) undertook the bioremedial clean-up treatment of hydrocarbon contaminated muddy gravel at one of their sites in Hungary. The muddy gravel was contaminated with TPH levels in excess of 300,000 mg/kg in parts and was a stern test for the feasibility of bioremediation within the region. The project was ...


  • Case Study - BP oil spill bioremediation tests

    CL Solutions, LLC has completed some internal preliminary testing of Munox SR® at the request of our customers and regulators in the Gulf Region. Although, our products have been used to remediate soil and ground water at numerous locations in the region, these tests were undertaken to verify specific applicability to the BP spill. Tar Ball Treatment While manual removal of ...

  • ISCR-Enhanced Bioremediation Accelerates Groundwater Cleanup at Active Manufacturing Facility

    In the winter of 2008, full-scale in situ chemical reduction (ISCR) was implemented as a removal action at the Siltronic Corporation site in Portland, OR, to treat a source area contaminated by releases of TCE. The source area was considered to be the portion of the site with concentrations of TCE in groundwater greater than 11,000 µg/L, suggesting the ...


  • ISCR-Enhanced Bioremediation of a TCE DNAPL Source Utilizing EHC® and KB-1®

    Remediation of chlorinated solvent DNAPL sites often meets with mixed results. This can be attributed to the diametrically opposed nature of the impacts, where the disparate dissolved phase plume is more manageable than the localized, high-concentration source area. A wide range of technologies are available for downgradient plume management, but the relative mass of contaminants in a ...


  • Compost Leachate Pond Bioremediation Case Study - Composting Facility, Northern California

    Our client runs a composting facility that receives green waste, food waste and other compostable material from residential and commercial sources, to create rich, black compost Challenge As part of the facility, the compost leachate pond has repeatedly experienced problems with the incoming influent high chemical oxygen demand (COD) and ...

  • A Feasibility Study for Assessment of In-situ Bioremediation Potential of a Crude Oil Degrading Pseudomonas Consortium

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • Bioremediation with compost of a diesel contaminated soil: Monitoring by dehydrogenase activity and basal respiration

    The effect of compost on hydrocarbon degradation was determined during a 120-d incubation period. An evaluation of soil basal respiration and dehydrogenase activity as a monitoring instrument for the bioremediation process of soil contaminated with commercial diesel-oil was carried out. Six soil samples were used: S (control, uncontaminated soil), CS (contaminated soil), CSS (contaminated and ...
