Path Forward provides expert support in vapor intrusion assessments within existing buildings as well as at proposed redevelopment Sites. Through soil gas, sub-slab soil gas, indoor air, and outdoor air sampling, our team provides solutions to even the most complex projects. We are experts in the vapor intrusion requirements of the California Environmental Protection Agency (CalEPA) including the California Department of Toxic Substances Control (DTSC), the California State Water Recourses Control Board (SWRCB), Regional Water Quality Control Boards (RWQCB), and the Office of Environmental Health Hazard Assessment (OEHHA), as well as guidance from federal agencies including the United States Environmental Protection Agency (USEPA) and local agencies including the Alameda County Department of Environmental Health (ACDEH), Bay Area Air Quality Management District (BAAQMD), South Coast Air Quality Management District (SCAQMD).

Once the scope of the issue is understood, our team can develop effective and efficient remedial solutions and/or design a Vapor Intrusion Mitigation System (VIMS) to ensure protection of human health to current and future occupants of buildings.
