EW 1 is located in the northwest corner of <br /> SMS Briners'tank yard (Attachment 2). The 154nch diameter borehole for EW 1 was initially <br /> drilled to a depth of 165 feet on October 25,2005 by Bradley and Sons using the reverse mud rotary <br /> method. An electric log was prepared by Welenco, Inc. on the same day. The well subsequently <br /> collapsed during its construction on October 26,2005. The upper 100 feet of the well casing were <br /> retrieved,and the hole was abandoned in the presence of a San Joaquin County environmental health <br /> specialist. <br /> On November 3,2005,another borehole was drilled about twelve feet west of the original borehole. <br /> The second 15-inch diameter borehole for EW 1 was drilled to a depth of 165 feet by Bradley and <br /> Sons again using the reverse mud rotary method. EW 1 was constructed using 8-inch diameter SDR- <br /> 17 PVC threaded casing with 29 feet of screen(three screened 9.98-foot segments including 0.33 foot <br /> thread). The screen(0.030 inch slot size)was placed between 127 and 156 feet in depth, and a four- <br /> foot sump with a solvent-welded PVC end cap was placed at the bottom of the casing. Casing <br /> centralizers were installed at the top and bottom of the screen and in 40-foot intervals to ground <br /> surface. The bottom five feet of the borehole filled in with native materials prior to the casing <br /> installation;a one-foot bentonite seal was placed between 159 and 160 feet in depth. SRI# 8 sand <br /> was placed in the well annulus as a filter pack between 104 and 159 feet in depth. A four-foot <br /> bentonite seal was placed between the filter pack and the sand-cement grout surface seal,poured in <br /> the presence of a San Joaquin County environmental health specialist on November 4, 2005. The <br /> well was completed with a steel-reinforced concrete surface pad and a PVC end cap was placed on <br /> the wellhead. The lithologic description of the borehole, the electric log,and the as-built well profile <br /> are provided in Attachment 3. <br /> EW 1 was developed by bailing and pumping(using an electric submersible pump) at rates of up to <br /> about 15 gallons per minute(gpm), including surging and swabbing. The well development was <br /> terminated when EW l produced water with a turbidity of less than 5 NTU at a pumping rate of about <br /> 500 F',-sC SCE- aL . Woodland CA 55655-4025 . 5306S10109 .
