Table 6. Predominant redox conditions at selected wells and piezometers, and ground-water geochemical data collected at Operable Unit 1, Naval Undersea Warfare Center, Division Keyport, Washington, 1996–2004.

[Shaded rows indicate previously unpublished data. All other data were published in Dinicola and others (2002), Dinicola (2003; 2004); prior to 2000, bicarbonate was calculated from an unfiltered sample. Reported concentrations less than the detection limit usually are estimated. A range of dissolved hydrogen concentrations are shown when equilibration at a single value was never achieved. Predominant redox conditions: A, aerobic; An, anaerobic, but specific redox condition could not be determined; Fe, iron reducing; M, methanogenic; Mn, manganese reducing; S, sulfate reducing. Abbreviations: nM, nanomolar; mg/L, milligram per liter; µS/cm, microsiemen per centimeter at 25 degrees Celsius; ORP, oxidation-reduction potential; mV, millivolt. Symbols: R, data rejected (selected 1996 dissolved-oxygen data were rejected because of inadequate well purging; selected 2002 dissolved-hydrogen data were rejected because of interference from downhole instruments); <, actual value is less than value shown; >, actual value is greater than value shown; –, not analyzed]
