This significant difference exists in the areal extent and source areas(s) of the 'TCE plume' as identified in the ROD. In March 1993, a thorough review of this remedial design data and all other existing ground water data was conducted by an EPA Hydrogeologist. The resulting conclusion of this review as that the 'TCE plume' is actually two distinct and separate contaminant plumes. These two plumes flow in opposite directions and based on information gathered to date, EPA has concluded that they result from difference sources.
