Abstract:

This study focused on improving our ability to confidently assess the groundwater to indoor air vapor intrusion VI pathway at chlorinated solvent-impacted groundwater plume sites. Federal, state, and local agency guidance has evolved toward multiple-lines-of-evidence-based approaches that involve indoor air, sub-slab soil gas, deeper soil gas, groundwater, and soil sampling in combination with empirical analysis and screening-level modeling. Of these, indoor air data tend to be most heavily weighted in decision-making.
