All Remedial Investigation Reports do contain Fate and Transport. Earlier AOI reports used the Domenico model to analyze the individual AOI areas. The decision to complete a site-wide Fate and Transport model to be included in a separate Remedial Investigation report allows Evergreen to evaluate groundwater flow and contaminate transport on a site wide basis, since the groundwater conditions are not bound by AOI boundaries. This cannot be completed until each of the AOI’s has been adequately characterized (indicated by agency approval of all RIRs). In addition, the proposed Fate and Transport Remedial Investigation Report will use a robust numerical 3D groundwater model which can more accurately predict groundwater contamination movement. Also note, that the most recent Remedial Investigation Reports for each of the AOI’s do include Fate and Transport in the form of qualitative analysis as allowed under Act 2.
