Due to the remediation efforts of Kerr-McGee, perchlorate concentrations have decreased overtime at both seeps. The average perchlorate concentration at the beginning of the samplingprogram was 97686 g/L at Kerr-McGee (LWC6.3) and 1503.85 ug/L at GCS5 (LWC3.7; Zhouet al, 2004). The average concentration has decreased 92 percent to 8097 g/L in 2005 at Kerr-McGee (LWC6.3) and 67 percent to 490 ug/L in 2004 at GCS5 (LWC3.7; Figure 13).3.1.8 Organic CompoundsA total of 177 priority organic compounds have been analyzed for all water samples collectedfrom all locations. The complete list of priority organic compounds along with the method anddetection limit is presented in Appendix A. Most of these organic compounds were below theanalytical detection limits in the samples. Appendix B lists the detected organic compoundconcentrations found in the individual quarterly samples from the locations. Table 11 shows theaverage concentrations of the organic compounds that were detected from more than one samplelocation. Concentrations of the most common organic compounds detected are presented inFigure 14.SampleSitePeriodSampled2,4-DAcetaldehydeBeta-BHCButanalButylbenzylphthalateLVC_2 2003-2007 0.78 11.03 ND 2.55 12.23 1.11 1.00 4.33 1.57 0.90 ND 21.34LW12.1 2003-2007 ND 11.46 ND 1.00 0.90 0.23 1.00 3.16 0.95 ND 1.76 18.68FW_0 2003-2007 ND 13.71 ND 1.00 3.56 0.58 1.90 1.12 1.32 4.15 3.14 14.99SC_1 2003-2007 1.29 7.96 ND 1.10 ND 0.11 0.70 ND ND 0.60 ND 13.30MC_2 2003-2007 ND 6.25 ND ND ND 0.13 ND 0.70 ND ND 14.10 9.14DC_1 2003-2007 ND 5.10 ND 1.00 0.80 0.12 ND ND ND ND ND 12.18BS_1 2006-2007 ND 18.00 0.29 ND ND ND ND ND ND ND ND 9.45LWC6.32003-Jan2006 ND 1.46 0.23 1.60 ND ND 15.28 ND ND ND ND 14.60LWC3.72003-July2004 ND 1.50 0.02 ND ND ND 0.60 0.67 ND 0.60 ND NDND = Not Detected*Numbers in the chart reflects organic contaminants that were detected from more than one sample location.Table 11: Average organic contaminant concentrations (g/L).CaffeineChloroform (Trichloromethane)Di(2-Ethylhexyl)phthalateDiethylphthalateDi-n-ButylphthalateDiuronFormaldehydeTributary Water Quality Monitoring Program, 2003-2007 25
