Sharpe Army Depot <br /> Well Decommissioning Analytical Summary <br /> Well Evaluation <br /> Shut down in July 2002. Upgradient/cross-gradient of NB COC plumes.TCE has not exceeded the ACL since 3Q06 and PCE has not exceeded the ACL <br /> EWNA1 since 1996(last sampled in 3Q10). MW477A provides more representative plume stability data in area.Sampling not necessary.Well recommended <br /> for clexommissioning in 2016 FFA Report. <br /> EWNA3 Shut down in July 2002. Upgradient/cross-gradient of NB TCE plume.TCE has not exceeded the ACL since 3Q05 and PCE has not exceeded the ACL <br /> since 2Q97(last sampled in 3Q10).Sampling not necessary.Well recommended for dexommissioning in 2016 FFA Report. <br /> EWNA8 Located off-site,downgradient of NB COC plumes.Well shut down in 2008. MW521A provides more representative guard well data.Well <br /> recommended for dexommissioning in 2016 FFA Report. <br /> MW494A Well monitored TPH contamination from UST 147.Site expected to be closed in 2017;sampling not necessary.Well recommended for <br /> clexommissioning in 2016 FFA Report. <br /> MW496A Well monitored TPH contamination from UST 147.TPH-d/TPH-g/TPH-mo not detected in 3Q14.Site expected to be closed in 2017;sampling not <br /> necessary.Well recommended for dexommissioning in 2016 FFA Report. <br /> Notes: <br /> Because of data quality concerns,data from the samples analyzed before 1996 were excluded from this evaluation. <br /> 3Q14=fourth quarter 2013(quarter/year) <br /> ACL=aquifer cleanup level <br /> CCI,=carbon tetrachloride <br /> COC=contaminant of concern <br /> DCA=dichloroethane <br /> DCE=dichloroethene <br /> EW=extraction well <br /> MW=monitoring well <br /> NA=not applicable <br /> NB=North Balloon <br /> PCE=tetrachloroethene <br /> SB=South Balloon <br /> TCE=trichloroethene <br /> TPH=total petroleum hydrocarbons <br /> UST= underground storage tank <br />
