Contaminant Removal Systems

Numerous methods are used for contaminant removal and trapping. Vista installs, following our client’s designs, several such methods, among them: Vapor Extraction Systems Air Sparge Systems Small scale pump and treat Sometimes, combinations of these are used either in different sequences or in different portions of the plume. Each is applied based on the information developed above and following the decision and designs of Vista clients. Vapor Extraction Systems Small-scale vapor extraction systems are installed using Vista’s Direct Push systems. Depending on depth and lithology, systems up to 2" in diameter may be installed. The design and operation of the systems remains with Vista’s clients. Along with the extraction systems, Vista has designed, installed, and operated vapor-monitoring systems, some of which have been continuous (see above description). Air Sparge Systems As with vapor extraction systems, smaller scale Air Sparge units can be installed. While many commercially available devices can be installed, in addition, Vista has installed a wide variety of less expensive tools, most based on slotted PVC pipe, in sizes ranging from 0.5 to 2" in diameter.
