� CAMBRIA <br /> Groundwater Elevations Static groundwater elevations gauged by Blaine on <br /> December 10, 2001 ranged from —20 91 to —20 49 feet <br /> referenced to mean sea level <br /> HYDROCARBON DISTRIBUTION IN SOIL <br /> TPHg was detected in soil samples from boring SB-5 at depths up to 50 5 fbg at concentrations <br /> ranging from 2,280 to 6,020 ppm No TPHg was detected in soil samples from boring SB-5 at or <br /> below 60 5 fbg Benzene was detected in soil samples from boring SB-5 at depths from 40 5 to <br /> 70 5 fbg at concentrations ranging from 0 0113 to 19 3 ppm Benzene was not detected in soil <br /> samples from SB-5 at or below 80 5 fbg MTBE was not detected in soil samples from boring <br /> SB-5 <br /> No TPHg, benzene, or MTBE were detected in soil samples from boring SB-6 <br /> No TPHg, benzene, or MTBE were detected in soil samples from well borings MW-10 and <br /> • MW-11 <br /> Soil chemical analytical data are summarized in Table 2 and TPHg, benzene, and MTBE results <br /> are presented on Figure 2 Laboratory analytical reports are presented in Appendix E <br /> HYDROCARBON DISTRIBUTION IN GROUNDWATER <br /> TPHg and benzene were detected in groundwater samples from boring SB-5 at concentrations <br /> ranging from 118 to 283,000 ppb and 2 29 to 51,900 ppb, respectively The highest <br /> concentrations of both TPHg and benzene were detected at 50 fbg, and concentrations drop off <br /> dramatically with depth in boring SB-5 No MTBE or other fuel oxygenates were detected in <br /> boring SB-5, although some elevated detection limits were reported <br /> TPHg and benzene were detected in groundwater samples from boring SB-6 at concentrations <br /> ranging from 95 3 to 1,670 ppb and 1 36 to 37 6 ppb, respectively MTBE and DIPE were <br /> detected by EPA Method 8260B at 50 fbg at concentrations of 33 8 ppb and 18 6 ppb <br /> respectively No other oxygenates were detected in boring SB-6 <br /> Results from the fourth quarter 2001 groundwater monitoring indicate that TPHg was detected in <br /> wells MW-3, MW-4, MW-6, MW-7, MW-10, MW-11, and VEW-2 at concentrations ranging <br /> from 120 to 82,000 ppb The laboratory noted that the TPHg detections for wells MW-6, <br /> 0854 6 <br />
