Abstract

The mass to concentration tie-in (MtoC Tie-In) correlates passive soil gas (PSG) data in mass to active soil gas data. Results from a site in Northern California show the MtoC Tie-In correlations for both benzene and Total Petroleum Hydrocarbons (TPH). The correlations are applied on a compound-to-compound basis to the remaining locations to provide an estimate of concentration that can be used for comparison to risk/screening levels or fate and transport diagnostic tools. Results from a chlorinated solvent survey show the MtoC Tie-In correlation from a site in Maryland for tetrachloroethylene. There was a near-perfect relationship between the passive soil gas (PSG) mass and the active soil gas concentration. The concentration estimated throughout a PSG-grid enables a vast new realm of interpretive power at sites. Several other sites are discussed. This is an abstract of a paper presented at the Petroleum Hydrocarbons and Organic Chemicals in Ground Water: Prevention, Detection, and Remediation (Houston, TX 11/3-4/2008).
