Tritium activities decreased in all three SALDS proximal wells during FY 2002, compared with FY 2001. Activities in well 699-48-77A first decreased to less than 3,000 pCi/L in January 2002, but rose to 150,000 in July, probably as a result of tritium discharges to SALDS that resumed in February 2002. Well 699-48-77C, where tritium analysis produced a maximum value of 750,000 pCi/L in January 2002, reflects the result of the delayed penetration of effluent deeper into the aquifer from tritium discharges. SALDS proximal well 699-48-77D produced a maximum result of 240,000 pCi/L in July 2002. Timing between detections of tritium and other constituents in well 699-48-77C suggest a delay of approximately three years from detection in wells 699-48-77A and 699-48-77D. Historically maxima for tritium (790 and 860 pCi/L in successive sample periods) suggest that tritium from SALDS may be reaching the northern edge of the 200 West Area, south of the facility
