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, ...

Detection of petroleum-contaminated soils using Equilibrium Headspace and Methanol Extraction
Petroleum spills and leaking underground storage tanks comprise a significant portion of remediation projects. Soil removal and disposal determined based on the contaminants and concentrations present. Specific target analytes are associated with this type of contamination. A number of these compounds are classified as volatile organics and are used to assess the severity of the contamination, ...

Setting the standards for headspace sampling by PID
The responsiveness of PIDs to virtually all VOCs has seen them become the accepted tool for initial site entry assessment, ensuring optimal detection of unknown and often toxic or hazardous chemicals found at hazardous waste sites and chemical emergencies. The speed and accuracy of modern PID equipment means that many worker and community safety concerns during initial and ongoing operations can ...
