Vapor Intrusion Investigations and Mitigation Services
Soil and groundwater contaminated with volatile organic compounds and/or chlorinated hydrocarbons release volatile chemical vapors such as PCE, TCE, benzene, toluene, ethylbenzene, and xylenes. These vapors can migrate upward through the ground and enter buildings causing a health risk to building occupants.
Vapor intrusion investigations are conducted to identify and assess upward moving vapors, and normally consist of soil and groundwater sampling, soil vapor extraction, and indoor air sampling. 
Depending upon site conditions, vapor intrusion mitigation can be accomplished by one or more of the following methods: soil removal, groundwater cleanup, sub-slab depressurization, sub-membrane depressurization, sub-slab pressurization, building pressurization, indoor air treatment, or passive barriers.
