Figure 3 is .� enlarged view of the former UST <br />are,a. <br />:s.l Soil Borings <br />�7n October 23 and 24, 2000, seven hollow-stem auger borings were drilled at the site (the <br />existing fire station prop�rty and the four southem adjacent residential properties). During <br />drilling, soil samples �vere collected for soil identification and/or chemical analysis. <br />Samples were collected using a 2.�-inch in.ner diameter split spoon sampler. <br />Five of these borings were completed for a concurrent gr.otechnical investigation (BH-1 <br />throug;h BH-S), extending [o depths of 6 to 16 feet. Two additional borings (BH-6 and BH- <br />7) were completed closer to be azea of the former gasoline release, located on the south and <br />west sides of the existing fire station building, respectively. These boring locarions were <br />selected based on the findings of the previously completed site investigations (as described <br />�.bove in Section 2.1) and the suspected azeas cf subsurface contamination. These two <br />borings extended to depths of SG to 60 feet. Selected soil samples (from BH-6 and BH-7) <br />were submitted to the analytical laboratory and analyied by the following methods: <br />Analyses <br />Total Petroleum Hydrocafions as Gasoline (NWTPH-Gx) <br />BETX (EPA 8021 B) <br />4��ntity <br />I 8 <br />Results of these analyses aze presented in Section 4.1 of this report. Please see our <br />description of the site exploration methods in Appendix B. Boring logs aze presented in <br />Appendix C. <br />3.2 Monitering Wells <br />Monitoring wells were installed into two of the completed hollow-stem auger borings (BH- <br />G and BH-7), identified as MW-1 and MW-2, respectively. Even though sufficient <br />groundwater was not identified during drilling of the borings, thesr, wells were installed to <br />obtain s�bstantia( documentation regazding the possible presence of groundwater and any <br />related contaminatie�. <br />OIAI05•C-RT.doc � � slOy(ICS <br />Copyright 2001 G•Logics, Inc.
