i QUARTERLY STATUS REPORT <br /> THIRD QUARTER 1994 <br /> 521 NORTH CHEROKEE LANE <br /> LODI, CALIFORNIA <br /> SITE CODE: 1324 <br /> (1C943 QSR, 25 October 1994) <br /> SAMPLING <br /> On July 22, and September 20, 1994, I measured the depth to an immiscible layer (where <br /> present) and depth to groundwater using the MMC Oil/Water interface probe A disposable <br /> bailer was used to qualitatively check for the presence of an immiscible layer not measured by <br /> the probe and purge those wells in which a "product" layer was not observed The bailer also <br /> was used to qualitatively check the probe measurement in MW-3 Although the probe measured <br /> an approximately 3-inch thick product layer in MW-3, the bailer check indicated an <br /> approximately 1/4-inch layer Given that the probe ceased to function later in the day and was <br /> subsequently diagnosed as having a low battery, the measured product thickness may not be <br /> correct. The measurements are summarized on Table 1 <br /> TABLE 1 <br /> Groundwater Measurements <br /> Location Date Depth Depth TOC Elevation Groundwater <br /> (IL) (Water) Elevation <br /> MW-1 2/07/94 NM 47.91 53.43 552 <br /> MW-1 7/22/94 NM 49 17 53.43 426 <br /> MW-1 10/20/94 NM 54.53 5343 -1 10 <br /> MW-2 2107/94 NM 4850 5403 5.53 <br /> MW-2 7/22/94 NM 49.75 54.03 428 <br /> MW-2 10/20/94 NM 51.10 54.03 2.93 <br /> MW-3 2/07/94 47.59 47.62 53.04 5 40* <br /> MW-3 7/22/94 4891 48.94 1 5304 4.08* <br /> MW-3 10/20/94 51 17 5048 53.04 2.01 <br /> Notes <br /> IL Immiscible Layer <br /> NM Not Measured <br /> * Corrected using 0 8 relative density multiplier and two significant digits <br />
