  • Dual bioremediation of phenol and Cr(VI) by mixed microbial cultures in the presence of molasses

    Simultaneous phenol and Cr(VI) bioremoval by two different mixed cultures, from petroleum-contaminated soil (PS) and boron-contaminated wastewater (BW), was investigated in regard to different culture media, pH levels (6–8), initial phenol (25–100 mg/L) and Cr(VI) (15–50 mg/L) concentrations. The optimum medium was found to be mineral salt medium tested, which contained 1% (v/v) molasses ...

  • 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 Interceptor contamination remediated - Case study

    What is an Interceptor Tank? An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff. Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the ...

  • Horizontal Well Systems for Improving Remedial Efficiency and Zone of Influence

    To improve remediation efficiency and expand the zone of influence, Directional Technologies, Inc. transferred technology from the oil and gas industry to the environmental industry. The oil and gas industry has used directional drilling for decades to improve oil recovery, based on a simple concept that the more screen contact there is with the “pay-zone,” the more production gained. ...

  • Per-and Polyfluoroalkyl Substances (PFAS) – An Emerging Challenge

    Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a large group of chemicals that were used for decades in numerous industrial applications (e.g., fire-fighting and metal plating foams, aviation hydraulic fluid) and consumer goods (e.g., stain repellent for clothes, furniture and carpets, and non-stick coatings). Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), both ...

  • Case study - Dual-reagent ISCO “Fast-Tracks” cleanup of Orlando Brownfield

    Description: A Brownfield property impacted with chlorinated solvents was the planned location for the home of the Orlando Magic basketball team. Contaminants: Chlorinated solvent contamination was present in soil and groundwater with PCE concentrations greater than 14,000 ug/L and potential presence of DNAPL. Remedial challenge: The ...

  • Case study - Coupling ISCO and anaerobic bioremediation at Kings Bay Naval Submarine Base wins state award of environmental excellence

    Site Description:  The Naval Submarine Base in Kings Bay, Georgia (a former landfill) was impacted with VOCs due to buried drums. Contaminants:  PCE and its degradation products at concentrations of 9,000 ug/L. Based on investigation efforts conducted by the Navy, DNAPL was also suspected. Remedial Challenge:  The groundwater ...

  • Hart`s E&P: Optimizing production, economics in mature fields

    To generate cash flow in low-price markets, operators have historically turned to the resource they can count on most—fields that have proved they can produce. But optimizing production from mature fields presents its own set of challenges that have the potential to offset the benefits of improved production with higher capital expense. Increasing production while lowering lifting costs and ...

  • Key Elements of a Successful Horizontal Remediation System

    Environmental remediation professionals around the country (and internationally) are rapidly learning that Horizontal Remediation Systems are an essential “tool in their remediation toolbox”. When designed and executed by experienced horizontal environmental drilling experts, Horizontal Remediation Systems can be extremely effective at achieving rapid site closure compared to vertical ...

  • Phenanthrene removal from liquid medium with emphasis on production of biosurfactant

    In the current study, there are some considerable issues which focused on: (1) the production of biosurfactant, (2) its correlation with the initial bacterial inoculum in the liquid phase and (3) its effect on polycyclic hydrocarbon (PAH) bioremediation performance. Therefore, two strains Pseudomonas facilis and Pseudomonas spp. were able to form a large clear zone diameter ...

  • World Oil: Proppant-sized solid inhibitors improve flow assurance in fraced wells

    The economic value of a hydraulically fractured well is highly dependent upon flow assurance—that is, maintaining unimpeded flow of hydrocarbons from the formation to the surface. Flow assurance issues occur in hydraulically fractured wells, as a result of the deposition and buildup of naturally occurring particulates that are present in the system during hydrocarbon production. Scale is ...
