Is Your Indoor Air Safe?
Vapor Intrusion (VI) is a condition where volatile organic chemicals (VOCs) enter building interiors, exposing occupants to potentially carcinogenic (cancer causing) substances. If you suspect there is a nearby source of VOCs (such as a dry cleaner or gasoline service station), GEOTERREN will evaluate your indoor air conditions by installing an interior sampling device for an approximate period of
24 hours for residences and 8 hours for commercial properties. The results will then be compared to San Francisco Bay Area Regional Water Quality Control Board Environmental Screening Levels (SFRWQCB ESLs). ESLs are conservative concentrations prepared by the SFRWQCB for a wide list of chemicals to be protective of human health and the environment.
Is Your Drinking Water Safe?
Old pipes and nearby sources of subsurface contaminants can contribute chemicals to your drinking water supply. GEOTERREN will sample your drinking water for a variety of chemicals, including lead, nitrites, e-coli, and other common contaminants. Similar to air sample results, the drinking water results will then be compared to ESLs.
