TO E RO E K SOP No.026,REv.1 <br /> ASSOCIATES,INC INDOOR AIR AND SUB-SLAB SOIL GAS SAMPLING METHODS <br /> I PAGE 2 <br /> 1.2 SCOPE <br /> This SOP applies to all personnel collecting indoor air and sub-slab soil gas samples in <br /> SUMMA®canisters.The site-specific work plan and sampling plan should be followed during <br /> indoor air and sub-slab soil gas sampling activities. <br /> 1.3 DEFINITIONS <br /> Indoor air: The gases or atmosphere filling the inside of an enclosed building or structure, <br /> such as a residence or commercial facility. The gases may be of natural origin, but <br /> manmade contaminants or byproducts may be present in detectable quantities from <br /> household products or by intrusion of contaminated soil gas. <br /> Sub-slab soil gas: The gases filling the void spaces in soils and unconsolidated sediments <br /> beneath a concrete building slab. These gases may all be of natural origin, but manmade <br /> contaminants or byproducts may be present in detectable quantities. <br /> 1.4 REFERENCES <br /> U.S. Environmental Protection Agency (EPA). 1990.
