WebA modeling study (Seyedabbasi et al. 2012) showed site characterization results (50-year-old, 675-kilogram release of TCE) consistent with late-stage sources. In late-stage sites, the contaminant mass in low-permeability matrices serves as the primary source material, resulting in elevated dissolved-phase concentrations for a longer period than the DNAPL … Web20 jul. 2024 · In situ chemical reduction involves the placement of a reductant or reductant generating material in the subsurface for the purpose of degrading toxic organic compounds to potentially nontoxic or less toxic compounds, immobilizing metals such as Cr (VI) by adsorption or precipitation, and degrading non-metallic oxyanions such as nitrate.

WebScreening for the vapor intrusion (VI) pathway must be conducted at every contaminated site in Wisconsin. The need to investigate VI is elevated when screening indicates the potential for VI is present, especially when trichloroethylene (TCE) is present due to its potential for acute (short-term) health risks.
