  • Screens

    WHEN it comes to selling compost, the markets can drive equipment purchase decisions. This was the case for the Lehigh County, Pennsylvania yard trimmings composting operation, which produced 14,000 cubic yards of compost in 2007. “We are doing a lot of work with a soil amendment company that makes products for golf courses,” says Tim Bollinger, Composting Operations Manager for the Lehigh County ...

  • Validation of a New Method for Screening Soil and Water for TCE Contamination

    INTRODUCTION ASTM Method D 7203-06, Standard Test Method for Screening Trichloroethylene (TCE)-Contaminated Media Using a Heated Diode Sensor, (ASTM 2006) can be used to screen a sample of soil or water known to contain the halogenated volatile organic compound (HVOC) TCE. The method calls for measuring the TCE concentration in the headspace above the sample using a heated diode sensor ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • Automated screening of explosives in soil samples by online SFE-SFC-MS

    There are a large number of explosives-contaminated sites in the US, Europe, and Asia. High levels of explosives in soil can threaten the health of humans, livestock, and wildlife. A number of remediation efforts are underway, which require the analysis of explosives in soil samples. Recently, a new technique was introduced that allows the automated supercritical fluid extraction and SFC ...

  • Are your field soil screening procedures providing you with practical and accurate information?

  • Recommendations to improve wildlife exposure estimation for development of soil screening and cleanup values

    An integral component in the development of media‐specific values for the ecological risk assessment of chemicals is the derivation of safe levels of exposure for wildlife. Though the derivation and subsequent application of these values can be used for screening purposes, there is a need to identify the threshold for effects when making remedial decisions during site‐specific assessments. ...

  • MB Screening Attachment Solves California Company’s Soil, Bark, and Wet Clay Problem

    For Timberline Tree Service, Inc., a powerscreen could not effectively break down wet clay at its facility. But a trommel screening attachment would. Initially, Timberline Tree Service, Inc. was looking for a machine to screen soil and bark. Once Tyler Willett, president of Timberline Tree Service, discovered MB Crusher’s screening attachment at World of Concrete 2016, he set out ...

  • Sensitivity of Ecological Soil screening levels for metals to exposure model parameterization and toxicity reference values

    Ecological soil‐screening levels (Eco‐SSLs) were developed by the USEPA (United States Environmental Protection Agency) for purposes of setting conservative soil screening values that can be used to eliminate the need for further ecological assessment for specific analytes at a given site. Eco‐SSLs for wildlife represent a simplified dietary exposure model solved in terms of soil ...

  • Fighting soil contamination with XRF

    Soil contamination Complying with new environmental regulations is a fast growing concern for companies and local officials tasked with ensuring that industries reduce pollution and clean up after themselves. It’s a particularly challenging issue when it comes to soil contamination It’s not always easy to detect as it silently contaminates crops and the ground water supply. XRF ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • Soil Vapor Extraction (In Situ)

    Introduction Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. ...

  • Chromium detection in water and soil...

    What is chromium? Chromium is a metal that is widely distributed in the earth’s crust (soil and rocks), air and water. Naturally occurring chromium occurs mainly in the chromium (III) form as chromite ore, which contains oxygen, chromium (III) and other metals such as iron. Chromium (VI) compounds are produced commercially from chromite ore for a wide variety of uses. ...

  • Horizontal Soil Vapor Extraction Wells

    As part of a Corrective Action Plan (CAP) submitted to NYSDEC, a consultant selected Horizontal Soil Vapor Extraction Wells (HSVE) to expand an on-site vapor extraction system in New York. Directional Technologies worked with the consultant on the horizontal well screen design and well layout of three (3) HSVE wells, spaced 50-feet apart, and constructed with 4-inch Schedule 80 PVC materials. Due ...

  • New Field Test for Lead (Pb2+) in Soil

    Field tests for the detection of lead in soil are not frequently accepted, since the tests are rather cumbersome or not reliable for screening determinations. Recently, we developed the LEADQuick field test kit for the detection of lead in water with 3 g/L sensitivity. This test is further modifiedto detect lead in soil with a sensitivity 0.03 g. We developed an extraction protocol using ...

  • Bioremediation of hydrocarbon impacted soils - Marchbanks, Dundee

    Client: Dundee City Council Objective: Bioremediation of hydrocarbon contaminated soils to achieve compliance with the Waste Acceptance Criteria (WAC) for Mineral Oil (C10 – C40); with the intention of re-using the soils to Riverside Recycling Centre to be used as a capping layer. Challenge: Approximately 2,800 m3 of hydrocarbon ...

  • Lead in Paint and Soil in Karnataka and Gujarat, India

    Blood lead surveys in several areas of India have found very high percentages of children with elevated blood lead levels. Fifty-three percent of children under 12 years of age in a sevencity screening had blood lead levels equal to or greater than 10 μg/dL, the level currently considered elevated by the U.S.  Centers for Disease Control and Prevention (CDC). A number of these surveys ...
