Client: Miller Homes Site Area: 3.03HA Location: Old Trafford, Greater Manchester Timeframe: 12 Months Challenge Design and delivery of a remediation strategy to treat extensive TCE-contaminated soil and groundwater, ready for development of 260 new homes. The derelict 3.03ha site had once been home to Manchester’s Itron gas meter factory, which opened its doors in 1933 before closing in ...
Introduction Bioremediation is the use of microorganisms, or their enzymes to clean up environmental pollutants. It is a sustainable and cost-effective approach to clean up contaminated soil, water, and air. Bioremediation can be applied to a variety of pollutants, including petroleum, pesticides, and solvents. Bioremediation is a complex process that involves various biochemical reactions, ...
Site Information Soil and ground water contamination by chlorinated solvents was discovered at a former industrial chemical mixing facility that was to be redeveloped as a shopping center. The contamination had leached from the soil underlying a drum storage area into ground water and spread across the property. While the area of ...
CL-Out was used to complete the remediation of ground water contaminated by chlorinated solvents from a former dry cleaning site in Rockville, Maryland. The ground water contamination had migrated from leaking sewer lines to underlying bedrock fractures. ...
Microbe could prove an economical, environmentally sound method of addressing stubborn dioxane co-contamination A pair of industrial solvents associated with cosmetics and household cleaning products has been detected at thousands of aquifer sites nationwide, according to a new study published in Environmental Science and Technology Letters.The United States ...
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 ...
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 ...
Site Background Data: 12 well dual-phase extraction system 2-acre encapsulation and treatment cell Well depths: 20-40 feet bgs; static water level: 15-20 feet bgs Approx. 30,000 cubic yards of soils contaminated with chlorinated solvents 25 HP rotary lobe blower used Each well extracts 20-30 scfm of vapor at 10-13" Hg Recovered vapor ...
EOS, or emulsified oil substrate, was used to stimulate anaerobic biodegradation of trichloroethene (TCE) and tetrachloroethene (PCE) at a former Army-owned manufacturing facility located in the Piedmont area of North Carolina. Previous use of chlorinated solvents at the facility resulted in soil and groundwater impacts. ...
Soil and ground water beneath the pit in the upper sand aquifer was highly contaminat-ed. Contaminants included various chlorinated solvents, benzene, and toluene. ...
Nano zero–valent iron (nZVI) is one of the most prominent examples of a rapidly emerging technology for the treatment of contaminated soil and groundwater. These particles were used successfully to absorb various heavy metals (e.g., Pb2+, Ba2+, As5+, As3+, Cr6+, Co2+, Cd2+, Cu2+), chlorinated organic contaminants (e.g., ...
is a source area bioremediation technology that enhances the dissolution of the chlorinated solvent contaminant and provides an electron donor for anaerobic reductive dechlorination (ARD). ...
Increasing regulatory attention to 1,4‐dioxane has prompted the United States Air Force (USAF) to evaluate potential environmental liabilities, primarily associated with legacy contamination, at an enterprise scale. Although accurately quantifying environmental liability is operationally difficult given limited historic environmental monitoring data, 1,4‐dioxane is a known ...
Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. ...
The Ivey-sol® Surfactant Technology is a patented Selective Phase Transfer Technology, that can desorb contamination for both soil and groundwater remediation; including contaminates such as hydrocarbons, chlorinated solvents, heavy metals, PCB’s, and PAH’s among other contaminants. ...
“Ivey-sol has proven to be very effective at liberating and dissolving petroleum hydrocarbons, chlorinated solvents, and heavy metals from soils and/ or groundwater, regardless of the type of contamination,” says George Ivey, Ivey International Inc. founder and CEO. ...
The oxygenase enzymes involved in the cometabolism of chlorinated solvents are not induced by the presence of contaminants, so a high microbial population has a proportionately high yield of oxygenase enzymes. Aerobic cometabolism of chlorinated solvents converts the contaminant to an organic ...
Site: Pilot Study – Trap & Treat® BOS 100® Colorado Contaminant: Chlorinated Solvent (TCE) in soil and groundwater Soil Type: Silty, sandy clays Injection Cost: ~$10,000 (material & labor) Treatment Area: ~1500 sq. ft. ...
Ozone oxidation systems like C-SpargeTM (microbubble ozone) and Perozone® (peroxide-coated ozone) are used for treatment of a variety of contaminants. From non-volatile to volatile compounds, from saturated to unsaturated compounds. The most common contaminants treated are chlorinated solvents, petroleum products and PAHs. ...
The RTDF is a consortium of industries and government agencies working together to access and pilot bioremediation technologies to clean-up soil and groundwater contaminated with chlorinated solvents such as trichloroethene (TCE). One project utilized accelerated anaerobic in-situ bioremediation to promote the anaerobic biodegradation of TCE and ...
