  • Vapor Intrusion Testing/Sampling in Buildings

    What is Vapor Intrusion? Vapor intrusion occurs when volatile chemicals lodged in soil or groundwater rise to the surface and are released into the air. This can occur in the open air or into buildings, offices, factories, warehouses, vacant, or abandoned. Vapor intrusion testing/sampling is a method of determining if known or suspected ground contamination is a result in these chemical ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...

  • Redwood City Case (In Situ Gas Thermal Remediation + C3 Technology (GTR™+C3))

    The former Dry Cleaner site was located in Redwood City, California, contaminated by tetrachloroethylene (PCE). Affected soils also contained low levels of PCE degradation byproducts, such as trichloroethylene (TCE), and were presumed to have an approximate extent of 384 square feet (16’ x 24’ area) to a depth of 10 feet beneath the building. The remediation goal was driven by vapor ...

  • Risk assessment of gaseous emissions from municipal solid waste landfill: case study Rafah landfill, Palestine
