Why should the fate and transport information be considered so early in the screening process?
While there are many uses of the fate and transport information throughout both the ERA and RI process, some of the primary reasons for the evaluation of this data at the screening level are to assess the effectiveness of the sampling locations utilized up to that point, to identify daughter or breakdown products that might not normally be considered, and to identify data gaps that need to be addressed to evaluate potential exposure pathways. It should be noted that fate and transport data should be considered even before the onset of the screening process during the work plan development phase.
