  • Soil Fracturing

    Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...

  • In Situ Remediation Technology Status Report: Hydraulic & Pneumatic Fracturing

    The purpose of this document is to describe recent field demonstrations, commercial applications, and research on technologies that either treat soil and ground water in place or increase the solubility and mobility of contaminants to improve their removal by pump-and-treat remediation. It is hoped that this information will allow more regular consideration of new, less costly, and more effective ...


  • Comparision of Installation Methods for Subsurface Placement of EHC™ for Treatment of Recalcitrant Groundwater Contaminants

    Untitled Document Presented at 15th Annual AEHS Meeting & West Coast Conference on Soils, Sediments & Water San Diego, CA Overview ...


  • Full Scale Bioaugmentation of a Low Permeability TCE Site Using KB-1®

    Problem DefinitionWidespread trichloroethene (TCE) contamination at Spill Site 7 has resulted from historical solvent spills at a former liquid oxygen facility that operated from 1960 to 1966. Site geology consists of low permeability and highly heterogeneous materials. The source area was located upgradient of a zero valent iron permeable reactive barrier (PRB). The project objectives included ...

  • In Situ Physical/Chemical Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • In Situ Remediation Technology Status Report: Co-Solvents

    ABSTRACT The purpose of this document is to describe recent field demonstrations, commercial applications, and research on technologies that either treat soil and ground water in place or increase the solubility and mobility of contaminants to improve their removal by pump-and-treat remediation. It is hoped that this information will allow more regular consideration of new, less costly, and more ...

  • New study sheds light on methane leakage from natural gas

    Natural gas wells represent a significant source of U.S. greenhouse gas (GHG) emissions, as many of them leak methane, which is more than 20 times more potent than carbon dioxide. But while scientists know that ...

  • New air quality rules challenge oil & natural gas industry

    EPA Administrator signed a suite of proposed new air regulations affecting both the Production/Processing and Transmission/Storage sectors of the oil and natural gas industry. The proposed rules mandate the use of emission controls as well as work practices through two different air regulatory programs – New Source Performance Standards (NSPS) and National Emissions Standards for Hazardous ...

  • 5 Pieces of equipment needed for the pipe bursting process

    Sewer pipe bursting looks a little bit like magic if you compare it to the traditional methods of sewer replacement. With the use of underground construction equipment, including directional boring equipment, sewer technicians are able to pull a new pipe through the old pipe without digging a hole into the top surface of the ground. The sewer pipe bursting method is the perfect pipe replacement ...

  • Five Additional Technologies Evaluated After ERH Application at Camp Lejeune

    Groundwater at Site 89 of Marine Corps Base Camp Lejeune in North Carolina is contaminated with two dense non-aqueous phase liquid (DNAPL) plumes and a large dissolved plume. The Navy took a phased approach over the past six years to address each of these components. In 2003, electrical resistive heating (ERH) was evaluated in a pilot study to treat one DNAPL plume. In 2006, field-scale ...

  • Abrasives case study - Carbo Ceramics

    It's been four years since Tom Sorensen has had to replace an elbow in his pneumatic conveying lines. But life wasn't always this easy for the maintenance manager at Carbo Ceramics' Eufaula, Ala. Facility. The company manufactures ceramic beads for use as proppants in oil and gas exploration and drilling. Global Giants such as Halliburton and Schlumberger pump the ceramic beads into well bores to ...

  • New NSPS OOOOa Regulations Affecting Methane and VOC Emissions from the O&G Sector Finalized as of June 3, 2016

    The EPA has issued three final rules that will curb emissions of methane, smog-forming volatile organic compounds (VOCs) and toxic air pollutants such as benzene from new, reconstructed and modified oil and gas sources, while providing greater certainty about Clean Air Act permitting requirements for the industry. The EPA’s amended and new regulations affecting methane (CH4) and VOC ...

  • Capturing the fugitives: Reducing methane emissions from natural gas

    The rapid expansion of natural gas development in the United States has been a double-edged sword. While natural gas supporters are quick to point out its economic benefits and green attributes—natural gas produces roughly half the carbon dioxide emissions of coal during combustion—this isn’t the whole story. Natural gas comes with environmental consequences, including risks to ...
