  • Bioaugmentation is a cost-effective and sustainable remediation alternative

    Selecting a remediation alternative that is compatible with the natural soil and ground water conditions is not only a more sustainable approach, but leads to significant savings. Comparison between bioaugmentation and other remediation methods in the five recognized sustainability criteria demonstrates the advantages of bioaugmentation. While this paper is nota complete quantitative analysis, it ...

  • Case Study: Aerobic Cometabolism of Vinyl Chloride in Central Ohio

    Site Summary: Chlorinated solvents were found in ground water at a former automobile repair shop. The solvents were thought to have been released from an underground storage tank (UST). After the UST and associated contaminated soil were removed, CL-Out® bioremediation was implemented to reduce the levels of contamination to site-specific cleanup goals. Geology and Hydrogeology The site is set in ...

  • Aerobics to the Rescue - Using Compatible Technologies to Improve Groundwater Remediation

    Background Increased opportunities for contaminated property redevelopment have propelled property owners to evaluate options for accelerating site remediation. In some cases a containment technology may have been implemented to mitigate the off-property migration of contamination as the most ...

  • The advantages and benefits of aerobic cometabolism

    Aerobic metabolism yields the energy-transferring molecule TPA at a much higher rate than anaerobic metabolism. The higher energy yield produces a greater viable population. 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 ...

  • Explosives remediation at Pueblo Chemical Depot changes course

    Treatment of soil and groundwater contaminated by energetic compounds has been underway since 1997 at area of interest (AOI) 3B of the Pueblo Chemical Depot (PCD) in Colorado. AOI 3B is part of the source of an explosives-contaminated groundwater plume. Initial work involved excavation and onsite composting of soil to address the contaminant source. In 2001, a pump and treat system using granular ...

  • In-Situ Anaerobic Remediation of Perchlorate-Impacted Soils

    AbstractARCADIS is currently leading the development, evaluation, and selection of a final groundwater remedy for a 94-acre manufacturing facility in the western U.S. This facility has produced small explosives and vehicular safety products since 1957. As a result of historic operations, soil and groundwater at the site have been impacted by perchlorate. To date, remediation efforts have been ...

  • Using AquaBupH to adjust aquifer PH: ESTCP-funded project at Charleston Naval weapons station - Case Study

    Elevated levels of trichloroethene (TCE) were found in groundwater at a Department of De-fense (DoD) facility in Charleston, SC. Under an ESTCP-funded in situ technology demonstra-tion project , the Navy had been effectively remediating contamination until a drop in aquifer pH caused dechlorination rates to decline. Solutions-IES responded with a study and applica-tion of buffered substrate to ...

  • Success in the Lab Leads to Success in the Field

    Success in the Lab Leads to Success in the Field Superfund Site in Pennsylvania  Problem:  Degrade TCE in the presence of 1,1,1-TCA   They said it couldn't be done. Most strains of Dehaloccoides (Dhc) would not dechlorinate TCE in the presence ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • 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% of ...

  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...

  • 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 ...
