Vapor intrusion can occur when volatile chemicals in buried wastes or contaminated groundwater emit vapors through subsurface soils and into the indoor air of overlying buildings. When this occurs, it often results in an indoor air quality problem. Soil gas and indoor air sampling are usually conducted to determine the type and level of the chemical(s) involved. Soil gas sampling is a highly effective tool used to identity subsurface contamination. When conducted properly, it can trace the source of the contamination, determine the extent of the contamination, and map the movement of the pollutant(s). Indoor air sampling in Vapor Intrusion studies collect parts per billion (ppb) level Volatile Organic Compounds (VOCs). Our expertise in this field helps to ensure the design of a proper delineation and monitoring plan for your most complex vapor intrusion issues.
