Field Screening Methods for the Presence of DNAPL, Superfund Site, southern California
Characterizing the lateral and vertical extent at a Dense Non Aqueous Phase Liquid (DNAPL) impacted site can prove to be a challenging task. Field methods employed to verify the presence of DNAPL have included the use of down-hole Ultraviolet Induced Florescence technologies, the application of down-hole detection materials such as dye impregnated fabrics, and the installation of monitor wells ...

Residential spill in VA
Laboratory analysis of soil samples showed high values of TPH/DRO showing an initial value of 18,800 and 8,300 ppm and the samples of soil analyzed after treatment with VaporRemed showed a value of 290 ppm and 210 ppm. Both these values are below the stipulated 500 ppm of TPH/DRO. The TPH in the drain water after flushing with the product showed values below the detection levels. The project was ...

Are your field soil screening procedures providing you with practical and accurate information?
Untitled Document Environmental consulting activities frequently require that on-the-spot decisions be made in the field concerning the presence or absence of volatile, or even semi-volatile, organic compounds (VOC's) in soil. There is nothing that can replace the value of field experience in 'making the right call' when the trucks are lined up, the backhoe operator is waiting, ...

Biopiles
Biopile treatment is a full-scale technology in which excavated soils are mixed with soil amendments and placed on a treatment area that includes leachate collection systems and some form of aeration. It is used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance ...

Lower costs, fewer delays - a highway expansion project applies XRF technology to obtain cost-effective remediation.
X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. In response to the growing need for field analysis of metals, many of these units have been adapted for use in the ...

Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil
ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...
