i <br /> 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 August 11, 1995 was approximately S89°E <br /> (very nearly due east) along a gradient of 0 003 foot/foot as shown on the Ground-Water <br /> Gradient Map, Figure 3 The flow direction has shifted 9° to the east and north since May 9, <br /> 1995 Sounding and flow direction data are listed 1n Table 1 <br /> TABLE 1 <br /> Ground-Water Sounding Data <br /> Carmen Punta Property-Stockton <br /> Well Sounding Depth to Casing-Top Water Table flow Direction a <br />' Nunber Date Water Elevation Elevation Gradient(Ft1Ft) <br /> (17t) (Ft AMSL) (Ft BMSL) <br /> MW-1 10/01/93 3965 10 87 -2878 N89°E @ 003 <br /> I 02/06/95 3672 -25 85 N83°E @ 004 <br /> 05/09/95 3292 -2205 S80°E Q 003 <br /> 08/11/95 3249 -21 62 S89°E @ 003 <br /> I MW-2 10/01/93 3831 9 65 -28 66 <br /> 02/06/95 35 17 -25 52 <br /> 05/09/95 31 35 -21 70 <br /> 08/11/95 3089 -21 24 <br /> MW-3 10/01/93 39 17 1028 -28 89 <br /> 02/06/95 36 19 -25 91 <br /> 05/09/95 3248 -2220 <br /> 08/11/95 3207 1 1 -21 79 <br /> IGround-Water Sampling <br /> Prior to normal well-sampling procedures on August 11, 1995, ground-water sampling <br /> equipment was steam-cleaned and/or washed in Ltqutnoxe prior to sampling and between <br /> samplings of each well Water-condition parameters of temperature, electrical conductivity, and <br /> pH were measured and logged during well-purging prior to sampling the wells Purging was <br /> continued until at least three well-volumes of water were removed from each well, and water- <br /> condition parameters had stabilized Well Sampling and Monitoring Logs are included as <br /> Appendix A <br /> Each ground-water sample was collected within a new, clean, disposable, polyethylene bailer <br /> lowered to gust below the plezometric surface Each ground-water sample was hoisted to the <br /> surface and immediately transferred to two, 40-m1 capacity, glass, Volatile Organic Analysts <br /> I (VOA) vials and two, 1-liter capacity, amber-colored, glass bars Each jar was fitted with <br /> WW Irian Inc <br /> Project No 33236 00 <br /> August 1995 4 <br /> I <br />
