Gaaoline and diesel lines were replaced and impacts; ' <br /> i soil was excavated and disposed of off site. Five groundwater monitoring wells were dr+' cd to <br /> help provide-nformation regarding groundwater quality and hydraulic conditions beneath the <br /> 1 site. Groundwater was encountered during drilling activities at the site at depths ranging from <br /> �1 1.5 to 3 fees below grade. Laboratory analysis of soil samples collected from each monitoring <br /> well determined that petroleum hydrocarbons were detected only in.well MW2. Monitoring well <br /> MW2 contained toluene and total xylenes in concentrations of 0.014 mg/kg and 0.027 mg/kg, <br /> respectively. Groundwater samples were collected from each monitoring well on site. Elevated <br /> concentrations of petroleum hydrocarbons were detected only in monitoring wells MW4 and in <br /> MW3 which is Iocated in the approximate location of the diesel leak. <br /> King i.lmd Pwon•307 <br /> ^� R0E1591.wp 7 . <br />
