  • 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 ...

  • Green remediation best management practices: site investigation

    Overview The need for site investigation is common to cleanups under any regulatory program. An investigation can occur at all points in the cleanup process, from initial site assessment through waste site closeout. A site investigation generally is undertaken to: Confirm the presence or absence of specific contaminants Delineate the nature and extent of environmental contamination ...

  • Site Closure Strategies: Reducing Remediation Liabilities & Costs

    Industrial companies face the daunting task of managing investigations and clean-ups at thousands of contaminated properties. In staying abreast of new technology and ever-evolving regulatory programs, companies must address many challenges involving regulations, technologies, and expenses. To successfully manage the costs and risks for each project, it is important to: 1) Focus on the ultimate ...

  • NJDEP issuing remedial priority scores for contaminated sites

    Very shortly, the New Jersey Department of Environmental Protection (NJDEP) will be issuing letters to responsible parties containing a draft Remedial Priority Score (RPS) for their particular site. It is unclear how the rankings will be used, but the RPS system has been described as a tool to sort sites out for further discussion. The ...

  • Combined Remedies Treat Large Industrial Site - Case Study

    ABSTRACT BOS 100 was successfully implemented as part of a combined remedies strategy to treat elevated levels of Trichloroethylene in a shallow fine grained aquifer at a former large industrial facility. CHALLENGES A large industrial facility used vapor degreasing in the 1970s and 1980s that resulted in chlorinated volatile organic compound (CVOC) ...

  • Active Taxiway Remediation

    Introduction: How do you remediate beneath an active airport taxiway without interfering with commercial airliners and United States Air Force cargo planes taxiing through your work area at 60 miles per hour? This was the problem facing the Department of Defense (DoD) at a site impacted with jet fuel. To solve the problem, our long-time client, FPM Remediations, ...

  • Remediation of mercury contaminated industrial site for future expansion - case study

    70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry® 12,000 has been in operation since early 2011. After the treatment the mercury free soils can be re-used on-site as building material. A similar but smaller econ industries ...

  • Mine remediation case study

    Bartow, Florida GeoView, Inc. performed a geophysical investigation across a 200 acre site in Polk County, Florida. It had been reported that clay slimes from former mining operations had been deposited on the site. The purpose of the investigation was to help determine the horizontal and vertical extent of the clay slimes. Due to the large size of the site and limited budget, the ...

  • 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 ...

  • A mixed-integer non-linear programming with surrogate model for optimal remediation design of NAPLs contaminated aquifer

    A mixed-integer non-linear programming (MINLP) with surrogate model was introduced to derive the optimal surfactant enhanced aquifer remediation (SEAR) process (remediation cost minimisation and removal rate maximisation) at a nitrobenzene-contaminated site. First, a 3D multi-phase flow simulation model was developed to simulate the SEAR process; using a radial basis function artificial neural ...

  • Experimental design of diffusion and desorption of contaminant in heterogeneous media

    Storage of contaminants in low permeability media (LPM) presents a great challenge for prediction of remediation effectiveness and efficiency. The reason lies in the contaminants' complex behaviors within heterogeneous media. Both interparticle and intraparticle diffusion contribute to the difficulty of precise site assessment. Sorption of contaminants – especially within LPM – may sequester the ...
