MONITORING WELL TRFITUM RESULTS FROM 4-10-09 SAMPLING EVENT Monitoring Wells MW-2, MW-3, MW-4, MW-7 and MW-1 1 were sampled on 4-10-09 as a follow-up from the 4-6-09 sampling event due to the increasing trend of tritium activity in MW-3.
Results from 4-10-09 were; MW-2 641 pCi/L (MDA was 526 pCi/L)
MW-3 60,232 pCi/L MW-4 <MDA MW-7 < MDA MW-11 < MDA Attached is the updated graph for MW's - 2, 3, and 11, and a map of the monitoring well locations.
Please let me know if there are any questions.
