PFAS, a component of aqueous film forming foam (AFFF), is different than the contaminants we have been treating for the last 30 years. On the atriplef.com website, we discuss how this affects our solutions, particularly when we face the challenge of removing AFFF from firefighting vehicles and equipment. The web page touches on:

Remediation Goals: 483 lbs VOC removal or 1,640,000 kWh applied.

Project Summary

TRS Group, Inc. (TRS), as a subcontractor to AECOM, completed a Standard Fixed Price Remediation (SFPR) of trichloroethene (TCE) in groundwater in Western Connecticut using Electrical Resistance Heating (ERH). The objective of the ERH project was to achieve the prescribed remediation goal for dissolved TCE in groundwater within the treatment volume. The system incorporated 89 electrodes with co-located vapor recovery (VR) wells to treat a soil volum

Contracting: Fixed Price Per Task

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 soil sampling indicated that all soil samples were below 1 mg/kg PCE and average soil concentrations

This project involved a guaranteed source area remediation of tetrachloroethene (PCE) at an operating school bus maintenance facility located in Queens, New York.

Engineer: Mr. Greg Beyke
Project Superintendent: Mr. Paul Bianco
Lithology: Clean sand in both the vadose and saturated zones.
Hydrology: Groundwater depth at 12 ft below grade surface (bgs).
Treatment Area, Depth Interval and Volume: 4,900 square feet, 9 - 55 ft bgs and about 8,350 cubic yards.

The U.S. EPA Region 10 office uses an adaptive site management approach that relies on high-resolution site characterization (HRSC) techniques for strategic sampling at the Well 12A project area. This approximate one-square-mile project area is one of three at the 2.5-square-mile Commencement Bay-South Tacoma Channel Superfund site in Tacoma, Washington. The vicinity of Well 12A, one of 13 wells used by the City of Tacoma to meet peak summer and emergency water demands, contains high concentr

Project Summary

TRS Group, Inc. (TRS) working with FLOYD|SNIDER a local Seattle consulting firm, completed a guaranteed fixed price remediation (GFPR) of tetrachloroethene (PCE) and trichloroethene (TCE) in soil at an active bulk chemical warehouse and distribution facility in Seattle, Washington. This contaminant source area remediation project was performed in accordance with

Guaranteed PCE and TCE Remediation at Hazardous Waste Facility

Project Summary

TRS Group, Inc. (TRS) completed a Guaranteed Fixed Price Remediation (GFPR) of tetrachloroethene (PCE), trichioroethene (TCE), cis-l,2-dichloroethene (cis 1,2-DCE), 1,1,1-trichloroethane (1,1,1-TCA), 1,1-dichloroethene (1,1-DCE), 1,1-dichloroethane (1,1-DCA), methylene chloride, and Freon 113 in soil and groundwater in Newark, CA. The goals of the ERH remediat

Guaranteed Remediation of TCE and 1,1-DCE in Soil and Bedrock

Project Summary

TRS Group implemented an electrical resistance heating (ERH) remedy to remove trichloroethylene (TCE) in overburden soil surrounding a former dry well located at a manufacturing facility in Shenandoah, Virginia. TCE soil concentrations were measured at levels that were indicative of separate-phase liquid. Initial mass-in-place calculations estimated that there were
