FINDINGS <br /> The groundwater flow is to the Northeast at a gradient of 0 . 0016 <br /> Ft/Ft. The groundwater level has risen about 3 . 3 feet, since <br /> the last quarterly reading. Figure 1 shows the water table <br />' elevations. <br /> Gasoline contamination is present in all of the wells above the <br /> California Action Levels. Also one of the hydropunch borings <br />' contained gasoline above the Action Levels. An isoconcentration <br /> plot of the Total Petroleum Hydrocarbons at each well and the two <br /> hydropunch borings are shown in Figure 2 . <br /> tOriginally three hydropunch wells were planned, however, boring <br /> HP-4 was not successful . The boring was advanced to a level of <br /> I 16 feet below the surface (bgs) where soil conditions caused <br /> refusal and drilling ceased. <br /> The CPT rig generates graphs which plot the tip resistance and <br />' fraction ratio during each 2 inches of drilling. These graphs <br /> have been analyzed for soil conditions and the results of <br /> the interpretation is shown of the three boring logs attached. <br />' Two cross sections incorporating the data from the hydropunch <br /> wells are attached. They are Figures 3 and 4 . The sections add <br /> information concerning the deep (55+Ft. ) clay layer found in well <br /> MW-11 but they do not indicate the reason for the contamination <br /> at HP-5. <br /> Presently the path of migration of the contamination from the <br /> site eastward moved mostly east but with HP-3 is north of the <br /> plume and MW-10 and HP-5 are near the northern and southern edge <br /> of the plume. Well NW-11 is near the eastern edge. <br /> CONCLUSIONS <br /> The next quarterly monitoring will take place in July, 1996 . <br /> This quarter we installed the vapor extraction wells at the site. <br /> I <br /> I <br /> I Page 2 <br />
