Table 2. Non-radioactive inorganic constituent concentrations and F-pseudosigma estimated sample standard deviations after purging 1 and 3 borehole volumes of water from selected wells during 2004 and 2005, with statistical comparisons of analytical results, Idaho National Laboratory, Idaho.

[See figures 1 and 2 for location of wells. Analytical results and F-pseudosigma estimated standard deviations are in milligrams per liter (mg/L) or micrograms per liter (µg/L). Shading indicates not statistically comparable at the 95-percent confidence level. Abbreviations: BHV, borehole volume; F-pseudos, F-pseudosigma estimated sample standard deviation; NA, not applicable; NC, not calculated; NS, not sampled; Repl., replicate sample; USGS, U.S. Geological Survey; Z-value, calculated using equation 1 (a Z-value less than or equal to 1.96 suggests statistical equivalence at the 95-percent confidence level); E, estimated; <, less than]
