Challenges Extended periods of mismanagement from previous owners left the facility and the wastewater treatment system in disarray. ...

  • Green remediation

    The US Environmental Protection Agency’s (EPA) strategic plan calls for increased research and application of sustainable systems that promote environmental stewardship, reduce greenhouse gas (GHG) emissions, and improve energy efficiency. One area of this research is green remediation. Green remediation is a relatively new approach to environmental cleanup; expanded from the traditional ...


  • Presumptive Remedies

    A presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site. EPA is establishing presumptive remedies to accelerate site-specific analysis of remedies by focusing the feasibility study efforts. EPA expects that a presumptive remedy, when available, will be used for all CERCLA sites except under ...

  • Groundwater Remediation

    Groundwater remediation or clean-up is required when concentrations of contaminants exceed or are expected to exceed predetermined levels for the type of resource that is impacted (Grossman et.al., 2008). For example, lead levels in drinking water should not exceed the EPA action level of 0.015 mg/L. What caused the high levels of lead? How can the lead be removed from the aquifer? (Grossman ...

  • Soil Remediation

    Contaminated sites by hazardous substances are a major environmental concern in Europe e throughout the world. Significant financial and human resources are devoted for the remediation of such sites. Many steps have been taken to restrict or ban from use some contaminants (PCBs, IPA, CLB-derivatives) and reduce discharge of others. However, contaminants can persist for many years in soil and ...


  • The power of precise remediation

    Design matters in in-situ remediation. Just ask Resource Geoscience, Inc. (RGI), a Remediation Products, Inc. BOS 200 approved installer and certified Trap and Treat Consultant. They recently demonstrated that when paired with proper injection design and precise application, BOS 200 can get the job done where others fail. The site:  Contaminated clay site in Colorado ...

  • Remediation: A business perspective

    The key to managing corporate environmental liabilities is to operate the remediation function as a business, recognizing that, like any business, it has a market, customers, and stakeholders. This article explains DuPont's business strategy for managing these liabilities. WHY IS A BUSINESS PERSPECTIVE SO IMPORTANT? Operating like a business is more about being financially disciplined than ...

  • Lake Jamno remediation proposal

    Lake Jamno………. near the city of Koszalin in Poland, has been contaminated by bio-mass sludge build-up from many years of agriculture run-off. Once a popular recreational and vacation destination, the Lake has been closed to swimming and boating since 2001. A Letter of Intent has been signed between the City of Koszalin and BluePlanet for the reclamation of Lake Jamno using an AQUACLEAN Treatment ...

  • A novel approach to remediating contaminated groundwater by reusing industrial co-products

    This paper presents a novel approach to remediating contaminated groundwater by utilising industrial co-products. The materials discussed include paper clay and steel slag, and the primary water contamination considered is heavy metal contamination. Paper clay was determined to have the potential for adsorbing heavy metals, and in compacted form could achieve permeability values within the ...

  • Remediation of Abandoned Coal Mines Using Coal Combustion Products

    A slurry of mine water and coal combustion fluidized bed ash (FBA) was injected into an abandoned coal mine in Eastern Oklahoma in July 1997. Oil-field technology was used to inject 1.8 Gg (418 tons) of FBA through five wells in 15 hours. Alkaline minerals in the FBA neutralized acidity and imparted alkalinity to the mine water. Thus, this remediation method uses the waste from an industrial ...


  • Remediation contracting, Northern England

    Project Remediation Strategies were requested to attend a redevelopment site in North-West England to supervise excavation works in an area of known hydrocarbon contamination and to assist the developer in the short term recovery of hydrocarbons. Workscope A Response Team was mobilised to site with a mobile oil-water separator, pumps, pipework and an oil ...

  • Risk 101 & Remediation Design

    Risk Assessment is the basis for almost all of our designs. Perceived risk is the basis for the rest of the designs. A good remediation design must incorporate the concentration goals for that site and the designer must know how those goals were set. In order to know how those goals were set, we all must have a basic understanding of Risk Assessment. Not just the numbers, but the methodology that ...

  • All Zero-Valent Iron (ZVI) Remediation Products ARE NOT THE SAME

    All Zero-Valent Iron (ZVI) remediation products ARE NOT THE SAME. The MAJOR DIFFERENCE between Emulsified Zero-Valent Iron (eZVI) and other ZVI products is the physical structure of the eZVI product, which is a water-in-oil emulsion. This structure makes the eZVI product hydrophobic, and therefore it is fully miscible with source material in situ. The water on the interior of the eZVI is the ...

  • Learn why All Zero-Valent Iron (ZVI) Remediation Products are not the same

    The MAJOR DIFFERENCE between Emulsified Zero-Valent Iron (eZVI) and other ZVI products is the physical structure of the eZVI product, which is a water-in-oil emulsion (see below images). This structure makes the eZVI product hydrophobic, and therefore it is fully miscible with source material in situ. The water contained in the interior of the eZVI emulsion provides the hydrogen for abiotic ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...
