� • i <br /> 5.0 CONCLUSIONS <br /> Two changes in groundwater conditions were observed during the third quarter First, the <br /> direction of groundwater flow has rotated approximately 90 degrees, and is now southward This <br /> may be a normal seasonal process due to agricultural or industrial pumping of wells in the vicinity <br /> Second, toluene was detected in monitor well TT-3, which is located dust south of the tank <br /> excavation These two changes are not necessarily related, although it is possible <br /> I Our previous conclusion that this site represents a low risk to public health remains unchanged <br /> Further assessment of the magnitude or extent of residual soil contamination appears <br /> unwarranted However, because of the minor changes in groundwater conditions, continued <br /> monitoring and sampling of the groundwater is probably justified Upgradient recommends that <br /> groundwater conditions be monitored during the fourth quarter before considering the site for <br /> case closure - <br /> I <br /> • 3 <br />
