Direct Detection of Residual Nonaqueous Phase Liquid in the Saturated Zone Using SF6 as a Partitioning Tracer

A study examined sulfur hexafluoride (SF6) as a potential detector of residual dense nonaqueous phase liquids (NAPL) below the water table. The results show that SF6 partitions to NAPL during transport.
