t <br /> The samples were recovered using clean, disposable bailers, and were then transferred into 40-m1 <br /> VOA vials All samples were labeled, placed in an ice chest, chilled on Blue Ice to 4° C, and <br /> transported to PET (an ELAP-certified laboratory) for analysis using appropriate chain-of-custody <br /> procedures <br /> The results of all current and previous groundwater soundings are summarized in Table 1 The <br /> average depth-to-water on February 14, 2001 was 11 25 feet below the top of the casing elevation <br /> of the three project monitoring wells At that time, the local direction of groundwater flow <br /> (utilizing elevation data from the monitoring wells) was calculated at approximately South 220 <br /> West along a gradient of 0 035 foot/foot (equivalent to 35 feet of dip per 1000 feet of horizontal <br /> ' distance) (see Figure 2) <br /> TABLE l <br /> HISTORICAL GROUNDWATER SOUNDING DATA <br /> Port of Stockton Former UST Site No 3,San Joaquin County <br /> Well Date Depth To Casing-Top Water Table Avg Flow Direction <br /> Number Sounded Water Ft Elevation Ft Elevation Ft &Gradient Ft/Ft <br /> MW3-1 07/09/99 1110 935 -175 East Northeast <br /> @ 0 004 ft/ft <br /> 10/22/99 1140 -205 North 40°degrees west <br /> @ 0 024ft/ft <br /> 02/08/00 1099 -164 North 16'degrees east <br /> @ 0 008ft1ft <br /> 05/17/00 1008 -073 East 22°degrees south <br /> @ 0 012ft/ft <br /> t� 09/14/00 1175 -240 South 6'degrees east <br /> @0 014ft/ft <br /> 02/14/01 1129 -194 South 23'degrees west <br /> 0 022ft/ft <br /> MW3-2 07/09/99 1089 922 -167 <br /> 10/22/99 1180 -258 <br /> 02/08/00 1089 -167 <br /> 05/17/00 967 -045 <br /> 09/14/00 1146 -224 <br /> 02/14/01 1112 -190 <br /> MW3-3 07/09/99 1039 874 -165 <br /> 10/22/99 1088 -214 <br /> 02/08/00 1023 -149 <br /> 05/17/00 929 -055 <br /> 09/14/00 1129 -255 <br /> 02/14/01 1135 9 -261 <br /> Well Sampling and Monitoring Logs are included as Appendix B <br /> Groundwater Sampling and Analyses <br /> Groundwater samples collected from the monitoring wells on February 14, 2001 and analyzed for <br /> ust slte3 gtr6 do 4 <br />
