  • 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 ...

  • Optimization design based on ensemble surrogate models for DNAPLs-contaminated groundwater remediation

    The optimization design of surfactant-enhanced aquifer remediation for dense non-aqueous phase liquids (DNAPLs)-contaminated groundwater is proposed through integrating simulation and optimization models. Many studies have demonstrated that the surrogate model is an effective tool for building a bridge between simulation and optimization models. In this paper, the simulation model was first ...

  • 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 ...

  • 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, ...

  • 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 10-year prospective on remediation

    For the last thirty years we have all been working very hard to put ourselves out of the remediation business, so why be concerned with where  remediation will be ten years in the future? In responding to environmental legacies of the past hasn’t industry put policies and procedures in place to prevent the creatin of future liabilities? Don’t we design and operate facilities today to minimize the ...

  • 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 ...

  • Recent papers in groundwater remediation

    Computational cost is a critical issue for large-scale water resource optimization under uncertainty, since time-intensive Monte Carlo simulations are often required to evaluate over multiple parameter realizations. This paper presents an efficient approach for replacing most Monte Carlo simulations with efficient surrogate models within a noisy genetic algorithm (GA). The surrogates are trained ...

  • Extraction well design for DNAPL recovery.

    The potential for downward migration of dense nonaqueous phase liquid (DNAPL) into deeper portions of a saturated hydrogeologic unit has important implications for successful groundwater remediation. Little information has been published regarding the design of extraction wells that allow DNAPL recovery without simultaneously creating a conduit for cross contamination by vertical migration ...

  • Case study - Petroleum remediation systems

    Overview A major oil company was looking for a way to stay ahead of EPA regulations for soil vapor extraction of BTEX and the subsequent treatment of these gases. They were looking for one company that could offer competitive pricing, local support service, and the application expertise to provide 50 remediation units throughout the ...

  • 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 ...
