V <br /> L <br /> SMTH <br /> 3.0 BACKGROUND <br /> On October 15, 1986, two 500 gallon gasoline underground storage tanks (USTs) were <br /> removed from the site. During removal of the USTs, petroleum product was noted present in <br /> the southern UST excavation (Figure 2). Soil samples were collected from 2 feet below the <br /> bottom of the USTs, and petroleum constituents and lead were detected in the soil samples. <br /> Analytical results for these soil samples are presenfed.in Appendix A. <br /> 4.0 PURPOSE <br /> The purpose of this site investigation is to determine if the soil and groundwater beneath the <br /> site has been impacted by the former USTs. To achieve this goal the following scope of work <br /> is proposed: <br /> L <br /> Permit and install three groundwater monitoring wells; <br /> Analyze selected soil samples for total petroleum hydrocarbons as gasoline (TPHg), <br /> and benzene, toluene, ethylbenzene and xylenes (BTEX); <br /> • <br /> Survey and develop .the new wells, purge and collect samples from the monitoring <br /> f wells; <br /> LPrepare a Problem Assessment Report (PAR). <br /> The workplan below describes in detail each of the tasks to be completed to determine impact <br /> on the soil and groundwater at the site from the former USTs on the site. All work described <br /> L in this workplan will be performed in accordance with Smith Environmental's Field <br /> Procedures presented in Appendix B and with the Site Safety Plan presented in Appendix C. <br /> 95122\W-0695.doc 2 <br /> L <br />
