For the Austin Unit,no significant changes in the water quality analytical results were noted. <br /> Luring the third quarter 20121 monitoring period, CLs were exceeded in detection monitoring <br /> program (DMP)wells AMW-2-, AMWJ1,AMW-121, A-N-IW-13 and A-NI -14. With the <br /> exception of the barium and chloride concentrations measured in well A M1W-14,none of the CL <br /> exceedances exhibited statistically significant increasing trends. It should be noted, however, <br /> that the barium and chloride concentrations measured in the sample collected from well A.'..vlW- <br /> 14 are vvithin the historical ranee of values oluserved at this well. For the corrective action <br /> program (CAP) wells, trend analyses are performed instead of comparison to C: s. During the <br /> current monitoring period, statistically significant increasing trends were noted for one or more <br /> VOCs in CAP wells AMW-I and ANIW-10. while several decreasing VOC trends we-re noted in <br /> CAP wells A2,VIW-1. AMW-4,AMW-5R, A-MW-10, and AMW-1 1. The increasing cis-1,2- <br /> dichloroethene trend in wells AMW-1 and AMW-10. suggest that active reductive dechlorination <br /> is occurring in the vicinity of these wells. <br /> according to the Forward Landfill Operations Manager,standard observations have been <br /> conducted weekly during the reporting quarter. The Forward Landfill Operations Manager also <br /> reported that no surface water was discharged from the facility during the reporting period. <br /> I certify'under penalty of law, that I have personally examined and am familiar with the <br /> information submitted in this document mid all attachments,and that based on my inquiry of <br /> hose individuals immediately responsible for obtaining this inforination.
