Focuses on the collection of soil gas samples for assessing the significance of the subsurface-vapor-to-indoor-air exposure pathway. While soil gas collection is not the only means of assessing this pathway, soil-gasplays a prominent role in recent guidance published by the American Petroleum Institute (API 1998) and the Unites Stated Environmental Protection Agency (USEPA 2002a). Fir example, these data can be used to help make decisions concerning:
-Resource Conservation and Recovery Act (RCRA) corrective action enviromental indicatiors (EI) for human health exposures
-Current exposure scenarios in existing buildings
-Future exposure scenarios in existing buildings
-Future exposure scenarios in future buildings
