  • PAH Bioremediation

    The results of a recent bench-scale test confirmed the effectiveness of a special blend of CL Solutions’ microbes formulated for PAH bioremediation.  The test results showed that after two weeks, the total concentration of 15 PAH compounds decreased by 85% from a total of 358 mg/kg to 50.9 mg/kg.  Benzo(A)pyrene is often a most difficult PAH to remove. The test showed that the ...

  • Test area North Chloroethene source area remediation project Case Study

    Background A contaminant source area resulted from the injection of chlorinated solvent-containing liquid waste and sanitary sewage to the Snake River Plain Aquifer from the mid-195s to 1972. The source is primarily an organic sludge containing up to 3% TCE. The sludge is present in the fractured basalt surrounding the former injection wells. A plume of TCE in ...

  • Perchlorate Remediation Project Case Study

    ARCADIS was contracted in 2000 to lead the development, evaluation and selection of a final groundwater remedy for this 94-acre site in California. As part of this work, ARCADIS is also participating in the evaluation of innovative technologies with the potential to treat soil impacts in the multiple source areas across the site. Specifically, the project is focused on the remediation of seven ...

  • Year-long effort secures California regulatory thumbs-up

    Working on behalf of client engineering firm URS Corporation, EOS Remediation brought the bioremediation product EOS® through unprecedented, custom testing to meet low-salt/low-metal regulatory standards for two California regulators. The result: a hard-to-secure regulatory approval for EOS®, which may be the only bioremediation product yet to meet these demanding state standards. EOS ...

  • Prj 9406 - Field Test for bioremediation of underground water contaminated by uranium mining operations

    BIOREM was tested on bedded waters contaminated from mining operation consisting in the in-situ leaching of uranium by sulfuric acid. The test was performed using the existing technological wells and comprised several variants. For simplicity it is reported the solution using two wells, one for injection and one for monitoring.            ...

  • 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 ...

  • Nanobite Cleans up Coastal Oil Disaster in Spain - Case Study

    On November 13, 2002, the Greek tanker The Prestige began losing its cargo of #6 bunker crude oil after one of its tanks burst off the northwest coast of Spain. The Spanish government decided to allow the tanker to sink, despite concerns of widespread contamination. By December’s end, the tanker had lost 80% ...

  • Nanobite bioremediates a Contaminated harbour - Case study

    When a hydrocarbon is spilled on water, it is very visible – floating on the surface, a blue green sheen clearly visible. When applied to an oil spill on water, Nanobite Liquid will not mix with the water and become diluted. Within a minute it attaches to the hydrocarbon, bonding with it and creating a matrix – an agglomerated gel- that remains on the surface and cannot sink, no ...

  • Evaluation of Aerobic and Anaerobic Degradation of Pentachlorophenol in Groundwater (PDF)

    Bench-scale laboratory tests were conducted to evaluate and compare the enhanced bioremediation of pentachlorophenol (PCP) in groundwater under anaerobic and aerobic conditions. While tests under both conditions showed a significant reduction of PCP over the 3-month test period (greater than 90 percent reduction compared to 40 percent in controls), removal to concentrations below the 10 μg/L ...

  • Bioremediation of Nitrochlorobenzene, Nitroaniline, Chloroaniline, and Other Organics in Groundwater.

    ABSTRACT: The uppermost aquifer beneath a chemical plant contains residual concentrations of o-nitrochlorobenzene from a tank car spill, as well as other plant-related organic compounds of concern (COC), including 2-nitroaniline and o-chloroaniline. The aquifer consists of low permeability clays and silts, and produces only a few gallons of groundwater per day from a shallow ...

  • Low-Cost Microbiotests For Toxicity Monitoring During Bioremediation Of Contaminated Soils

    Abstract: This paper addresses in the first place the need to apply toxicity tests with batteries of species from different trophic levels for an (ecologically meaningful) determination of the toxic hazard of contaminated soils. Furthermore, \'direct contact\' tests must be performed as well as assays on pore waters, leachates or percolates.Most toxicity tests available to date ...

  • Semifield testing of a bioremediation tool for atrazine‐contaminated soils: Evaluating the efficacy on soil and aquatic compartments

    The present study evaluated the bioremediation efficacy of a cleanup tool for atrazine‐contaminated soils (Pseudomonas sp. ADP plus citrate [P. ADP + CIT]) at a semifield scale, combining chemical and ecotoxicological information. Three experiments representing worst‐case scenarios of atrazine contamination for soil, surface water (due to runoff), and groundwater (due to leaching) were performed ...

  • DOD evaluates bioaugmentation for remediating low-pH aquifers

    The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...
