<br /> ' Contingency Pian
<br /> 1)tf concentrations of manganese,iron,arsenic or barium in transition well MW.24,BP,MW-25-BP or compEance well MW-2•BP or MW-5-BP Increase by greater than 20'h compared to basefute AND backgfound favals(based on concenlrafons in MW-7-BP),tvn consecutive monthly samples vnll be Wlected from the affected well(s)and the background well and analyzed for the elevated matals.The background well Is Included
<br /> In this evaluation because inorganic constituent concentrat%ons that have Increased by mora than 20%In the background well wotfd be in(ricative of analytical uncenta'nty,or possUle charges In the aquifer chemistry not related to EOS remedation.
<br /> 21 If manganese,Iron,arsenic,or bar um concentrations in MW-24-BP,MW-25-6P,MW-2-BP andlor MW-5-BP do not decrease below 120%of baseroe or background levels after two consecutive sampling events,more frequent sampCng in the affected weg(s)wig continue un®concentrations decrease to ltelav J20%of baseMe or background levels,whichever is higher.
<br /> ..)If manganese,Iron,arsenic,or barium concentrations In MW-2-BP andror NEW-5-BP do not decrease beam 120%of baseline or background levels after 6 months,a removal action wig be considered and discussedwttlt the RVYM!3,
