.u, <br /> F <br /> NINE IMI, <br /> I <br /> { , i <br /> _ E <br /> While the BAT technology is proven in laboratory and controlled field testing,the system <br /> is gene;ally not recommended as a replacement for monitoring wells due to its depth <br /> -- discrete technique and its inability to produce the large volumes of water genera{ - <br /> required for ane generally <br /> analysis, However, the advantage of this technique as a screening tool, to <br /> assess the optimum lat®ral and vertical location of monitoring wells and remediation <br /> wells, or for long term monitori�-rg within a ho+�neneous soil or at a discrete depth, hay <br /> been p"=oven on this site. Lack Of correlation between the chemi <br /> Wry BAT sampling probes and the monitoring wells indfcafes that coal obtained by the <br /> distributed throughout the saturated zone as indicated contamination is not <br /> comparison of BAT chem{ by the monitoring wells. A valid <br /> chemistry data to monitoring well data would require installation and <br /> sampling of numerous BAT sampling probes over the entire completion interval of the <br /> Monitoring wells, f <br /> 1 <br /> ,i <br /> t <br /> _ t <br /> r <br /> I <br /> :`. <br /> ,S <br /> ifi <br /> Fr <br /> 17 <br /> f <br /> 1 i we <br /> - - X13 •. <br /> .. , ,. <br />
