Each soil sample was analyzed for Total Petroleum Hydrocarbons, by EPA <br /> -' Methods 8015D (diesel) and 8015G (gasoline) and for Volatile Aromatic Compounds <br /> (BTEX) by EPA Method 8020. <br /> There was no tank testing done prior to the removal of the tanks so it is difficult to <br /> estimate the total quantity of product lost. There were no other spills, leaks or <br /> accidents at the site. There was no previous subsurface work noted at the site or in <br /> !y <br /> the adjacent area. <br /> 11. SITE DESCRIPTION <br /> i <br /> The Ceco Building site is underlain by Quaternary alluvial deposits, consisting of <br /> undifferentiated arkosic alluvium of the Modesto Riverbank Formation. <br /> Figure 2 is a site map showing the location of buildings, former underground storage <br /> i <br /> �..,nks and fuel pump island, piping and subsurface conduits. <br /> Copies of the thirteen photos showing various aspects of the fuel island area prior to,. <br /> during and after the tanks removal are presented in Appendix 1. <br /> 2 <br /> _ i ; <br />
