The soundings were converted using casing-top elevations previously established by RFA The <br /> elevation data were used to calculate the present ground-water flow direction and gradient by <br /> the three-point method The local flow direction on May 9, 1995 was approximately S$0°E <br /> along a gradient of 0 003 foot/foot as shown on the Ground-Water Gradient Map, Figure 3 The <br /> flow direction has shifted 17° to the east and south since February 6, 1995 Sounding and flow <br /> direction data are listed to Table 1 <br /> ' ABLE 1 <br /> Ground-Water Sounding Data <br /> Carmen Punta Property-Stockton <br />' Water Table <br /> Well Sounding Depth to Casing-Top EtevatIou Flow Direction 0 <br /> Number Date Water Elevation (Ft BMSL) Gradient(EM) <br /> (Ft) (ft AMSL) <br />' MW-I 10/01/93 3965 1087 -2878 N89°E?@ 003 ft/ft <br /> 02/06/95 3672 -25 85 N83°E g 004 ft/ft <br /> 05/09/95 3292 -2205 S80-E @ 003 ft/ft <br />' MW-2 10/01/93 3831 965 -28 66 <br /> 02/06/95 35 17 -25 52 <br /> 05/09/95 J 3135 _2170 <br /> MW-3 10/01/93 39 17 1028 -2889 <br /> 02/06/95 36 19 -25 91 <br /> 05/09/95 3248 -2220 <br />' Ground-Water Sampling <br /> Prior to normal well-sampling procedures on May 9, 1995, ground-water sampling equipment <br /> was steam-cleaned and/or washed in Liquinox®prior to sampling and between samplings of each <br /> well Water-condition parameters of temperature, electrical conductivity, and pH were measured <br /> and logged during well-purging prior to sampling the wells Purging was continued until at least <br />' three well-volumes of water were removed from each well, and water-condition parameters had <br /> stabilized The Well Sampling and Monitoring Logs are included as Appendix A <br /> WW I"n Inc <br /> Project No 33236 00 <br /> May 1995 <br /> 4 <br />
