Although previous site remediation efforts have highlighted the importance of sewer lines in transporting VOCs, sewer lines are not routinely sampled during most vapor intrusion investigations, and their role as pathways for vapor intrusion is poorly understood. Results from the tracer study at the USEPA vapor intrusion research duplex (Indianapolis, Ind.) demonstrated the migration of gas from the sewer main line into the duplex. The migration pathway appears to be complex and may include leakage from the sewer lateral at a location below the building foundation. These results combined with results from the prior multi-year study suggest sewer lines should be routinely evaluated as part of vapor intrusion investigations.
