Contaminated Land Measurements
Contaminated soil is a problem for ground waters as well as for residential areas constructed on former industrial areas or brownfield sites. Chlorinated VOC’s in particular present significant heath problems when evaporating from contaminated land into buildings.Potentially contaminated areas can be screened by drilling wells into the ground and measuring evaporating gases from these wells. Typical contaminated soil gas components include: 1,1,1-Trichloroethane, Trichloroethylene, Tetrachloroethylene, Chloroform, Benzene, Toluene, p-Xylene, 1,1-Dichloroethylene, cis-Dichloroethylene, Perchloroethylene, Dichloromethane.
For the infrared determination of total oil and grease (TOG) or total petroleum hydrocarbon (TPH) concentration levels in water or soil using an external solvent-based extraction procedure. Five models are available, depending on the solvent being used for the extraction process and required measurement range. No matter what solvent you use for your extraction process, there is an Infracal TOG/TPH Analyzer to handle the analysis accurately and reliably.
The ability to rapidly analyse (ppb – ppm) soil samples on-site is a major advantage for contaminated land assessment and remediation projects. The measurement of the concentration and type of organic pollution enables site staff to make quick, informed decisions without incurring the delays and costs associated with laboratory analysis; it also saves downtime and can avoid exposure of groundwork crew to hazardous VOCs.
