  • 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 ...

  • E-Z Trays selected for Large scale project - Case Study

    A former industrial plant and top Superfund site in Sydney, Australia, had been in operation since the 1930s and contained chlorinated solvent contamination. Because of the size and scope of this project packed towers traditionally would have been the air stripping method of choice, but the client was concerned about the ability of workers having easy access to maintain and clean the units. They ...

  • Investigation of associations between chemical element contents in native lichens and childhood leukaemia

    After a study in which the harmful atmospheric chemical elements (As, Hg, Ni, Pb) were investigated as leukaemia inducers, we have extended this work to 22 chemical elements using data from a lichen survey held in 1993 in Continental Portugal and childhood leukaemia death counts in 275 counties for the period 1991?1998. Kriging models were used to estimate lichen biomonitoring measurements at the ...

  • Bioremediation Consulting Inc (BCI) develops an anaerobic chloroform-degrading culture

    BCI’s newest culture is a microbial mixture (consortia) which can transform chloroform (CF) to dichloroemthane (DCM), a transient intermediate which is then converted to a non-chlorinated product.  We have demonstrated that the culture can dechlorinate at least 10 ppm of chloroform. Dechlorinating Bacteria in BCI Cultures. To address single compounds or a mixture of chlorinated ethenes, BCI ...

  • Bioaugmentation and Biostimulation Create Conditions for Successful Site Remediation

    CASE SUMMARY Dry Cleaning Operations, Coral Springs, FL A subsurface chlorinated solvent plume formed as the result of dry cleaning operations and migrated beneath an onsitestructure. Over a 6-month period, the concentration of chlorinated solvents increased from 6,000 to 15,000 partsper billion (ppb). A low-cost, in-situ remedial strategy was sought to treat the ...

  • DNAPL in Clay Formation

    PROJECT BACKGROUND At a manufacturing site located in Cookeville, TN, on and offsite soil (tight clays) and groundwater contaminated with chlorinated solvents, were discovered as the result of a Phase I and a Phase II investigation. The client entered the State of Tennessee Voluntary Clean-up Oversight and Assistance Program (VCOAP), which resulted in an informal focused feasibility study to ...

  • Grid and Barrier Treatment Reduces Chlorinated Solvent Contamination

    CASE SUMMARY Manufacturing Facility, Dallas, TX Subsurface investigations at this manufacturing facility revealed chlorinated solvent contamination in the groundwater. The contaminant plume contained significant levels of dichloroethene (cis-DCE) and vinyl chloride (VC) from the natural attenuation of tetrachloroethene (PCE) and trichloroethene (TCE). Well MW-9 contained ...

  • Nipper Tower Brownfield Remediation Project – Camden, NJ

    Site Summary Built between 1915 and 1916, the “ Nipper Tower,” with its’ stained glass rendition of the RCA trademark of the Nipper dog listening to a phonograph watched over the Camden, NJ waterfront for 80 plus years. In 2000, a localdeveloper sought to redevelop the abandoned, vacant, underused and contaminated property (Brownfield) and move it back into productive use. The Nipper ...
