Post ConcentrationSite Scale
With this choice, the decision basis is applied to the entire site. If polygons are present, then the criteria applies to the interior of the polygon. Under site scale, the blocks are remediated by replacing the contoured value with the post remediation concentration. This process is implemented from most contaminated blocks to least contaminated blocks until the site average falls below the decision criteria. For certain choices of clean up goal and post remediation values, a remedial design may not be possible. It is not necessary, however, that the post remedial concentration be less than the decision goal. For pooled data, the individual post remediation concentrations for each contaminant are used and a resulting risk value from these pooled post remedial values is generated.
