  • Estimating contaminant-flushing rates for heterogeneous aquifers

    Groundwater remediation evaluations typically include cleanup time projections. Current batch flushing-rate equations and analytical models often used to estimate groundwater cleanup rates typically underestimate cleanup times, with a major factor the flawed assumption of aquifer homogeneity. Numerical modelling of groundwater flow and contaminant transport is a time-intensive and costly ...

  • Case study - Gas plant groundwater remediation

    One-pass trenching method used for a gas plant groundwater remediation project Not many environmental engineers have heard of one-pass trenching and even fewer have actually applied this cutting-edge technology to environmental control and clean-up. However, a growing number of companies are starting to use this technology, resulting in decreased cost of installation and increased system ...

  • Enhanced Bioremediation of Tetrachloroethene in Central Indiana Glacial Till

    ABSTRACT: The goal of this project is remediation of soil and groundwater impacted by tetrachloroethene (PCE) that infiltrated the vadose and uppermost saturated zone below an active dry cleaning facility in central Indiana. PCE was released and transported to depths less than five meters via the primary porosity of thin sand and silt stringers and via secondary porosity of fractures in lodgment ...

  • Source Area Remediation of PCE in Soil - Fair Lawn, New Jersey - Case Study

    TRS Group, Inc. (TRS) was retained by Anderson Mulholland and Associates, Inc. (AMAI) to perform an Electrical Resistance Heating (ERH) remediation of DNAPL in soil at the former Topps Dry Cleaners property in Fair Lawn, NJ. The remedial goal of this project was a reduction of tetrachloroethene (PCE) in soil to less than 1 milligram per kilogram (mg/kg) in every soil sample. Final confirmatory ...

  • Hired metals analyser ensures remediation success

    Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been possible to meet the deadline without the use of ...
