【 摘 要 】

This report updates a continuing groundwater quality assessment for single-shell tank Waste Management Area S-SX at the Hanford Site. This report covers November 1997 through April 2000. Major new findings include the following: groundwater contamination continues to persist in both the northern half of the Waste Management Area as well as the southern half; evaluation of changes in water table elevations indicates a gradual shift in the direction of groundwater flow from the southeast to a more easterly direction; discrete depth sampling suggests mobile tank waste contaminants are at the very top of the aquifer in downgradient wells along the southeast side of the SX tank farm.
