<br /> WORK PROPOSED FOR NEXT QUARTER (Fourth 2003): t
<br /> 1. Stratus will continue to remove floating product from well MW-1 on a weekly basis, monitor free
<br /> product thickness in selected wells, and remove floating product when present. ,4
<br /> 2. The next sampling event is tentatively scheduled for December 2003. Groundwater samples will be ,I
<br /> analyzed for total petroleum hydrocarbons as gasoline (TPHG), benzene, toluene, ethylbenzene,
<br /> total xylenes (BTEX), tertiary butyl alcohol (TBA), methyl tertiary butyl ether (MTBE), di-Isopropyl J
<br /> ether (DIPE), ethyl tertiary butyl ether(ETRE), tertiary amyl methyl ether (TAME), 1,2-dichloroethane i
<br /> ii (1,2-DCA), 1,2-dibromoethane (EDB), and ethanol using USEPA Method 8260B.
<br /> 3. Once offsite access is granted, Stratus will implement the scope of work outlined in the Work Plan
<br /> t `E dated October 15, 2002.
<br /> 4. Stratus will coordinate with PG&E for procuring a power supply to operate the SVE system.
<br /> 5. Upon receipt of ATC, Stratus will conduct system startup and source testing.
<br /> DISCUSSION
<br /> i During the weekly visits to the site and the quarterly monitoring event, product was measured in well
<br /> MW-1 at thicknesses ranging from 0.05 to 0.07 feet thick, and in well VW-4 at approximately 0.10 feet i
<br /> 1 9 9
<br /> thick. During each site visit, free product in the wells was manually bailed, and placed in properly labeled
<br /> DOT approved drums pending disposal. Approximately 25 gallons of a product/water mixture was bailed
<br /> from wells MW-1 and VW-4 during the third quarter 2003. Approximately 149 gallons of product/water
<br /> mixture have been bailed to date. Product thickness measurements and volumes of liquid bailed are {
<br /> a summarized in Table 1.
<br /> In wells MW-3, MW-4, MW-6 through MW-9, VW-1 through VW-3, VW-5, VW-7, VW-10, VW-14, VW-18, I
<br /> and VW-20, there was less than 1 foot of water column in the well; the water in these wells does not
<br /> appear to be formation water. Wells MW-5,`VW-8, VW-9, VW-11, VW-16, VW-17, and VW-19 were dry.
<br /> Well VW-15 was obstructed. Groundwater in wells screened within the upper water-bearing zone (MW 2,
<br /> { VW-5, and VW-6) were measured at depthsbetween 43.99 and 59.85 feet below bgs, approximately 0.46 i
<br /> " to 5.31 feet lower than groundwater elevations measured during the second quarter 2003. Groundwater f
<br /> �j in well MW-1 (screened in the lower water bearing zone) was measured at 104.97 feet bgs, 0.05 feet 1i
<br /> higher than the groundwater measured during the second quarter 2003 event. These data are similar to
<br /> groundwater data from previous quarters. . Groundwater measurements are summarized in Table.2.
<br /> . Groundwater elevations are included in Figure 2. Wells that contained a small amount of water but are
<br /> interpreted to be dry are indicated as dry on Figure 2. j
<br /> During the third quarter 2003 sampling event, TPHG and benzene were reported in the sample collected
<br /> i from well VW-6. TPHG was also reported in well MW-2. The highest concentrations of TPHG
<br /> 9,500 /L and benzene 5,900 /L were reported in well VW-6. Fuel oxygenates, including MTBE,
<br /> were not reported in any of the wells. Petroleum hydrocarbons or fuel oxygenates were not reported in the
<br /> domestic well. These data are similar to chemical.analytical data from previous quarters. TPHG,
