Soil Gas Characterization refers to the methods utilized to collect vapor data at sites potentially affected by volatile organic compounds (VOCs), including chlorinated solvents, petroleum hydrocarbons, methane, hydrogen sulfide and semi volatile organic compounds (SVOCs) as well as toxic or carcinogenic chemicals of concern. The data obtained from a soil gas investigation can be used to identify the source and spatial distribution of contamination at a site or to estimate indoor air concentrations for risk assessment purposes.
Additional capabilities of Terra-Petra include:
- Registered Environmental Assessor on staff with extensive experience in Soil Gas Characterization.
- A thorough understanding of the California Department of Toxic Substance Control (DTSC) Vapor Intrusion Guidance.
