When volatile organic compounds (VOCs), such as chlorinated solvents or petroleum products, are released into the soil and groundwater, they can mix to form a soil gas plume. When the gas moves towards or into buildings, it is known as vapor intrusion (VI). Vapor intrusion can impact public health and property values. RMS performs vapor intrusion assessments, evaluate potential VI exposure pathways, manage associated risks, and assess compulsory responsibility. We perform near slab, sub slab and indoor air vapor intrusion investigations according to the applicable rules and guidance.
RMS evaluates the vapor intrusion results and pathway to determine the potential impacts to on-site and nearby receptors and we understand the reporting requires specific to each state and when an Immediate Environmental Concern (IEC) is identified. We understand that multiple lines of evidence are needed to properly interpret vapor intrusion results and make decisions.
