Table 2. Concentrations of tritium, strontium-90, and cesium-137 in perched ground water from selected wells, Reactor Technology Complex, Idaho National Laboratory, Idaho, 1999–2001.
[Well No.: Locations of wells are shown in figure 3. Analyses completed by the Radiological and Environmental Sciences Laboratory. Analytical uncertainties are reported as 1 times the sample standard deviation. Concentrations equal to or greater than 3 times the sample standard deviation are considered to be greater than the reporting level and are bold. Abbreviations: DP, well completed in deep perched water; QA-3, quality assurance replicate sample, number indicates the replicate sequence number during a sampling event; SP, well completed in shallow perched water; NR, analysis not requested; NS, not sampled due to lack of water or because water level was below pump intake; NSO, not sampled because of obstruction in well; NSA, not sampled because of well access problems; NSEQ, not sampled because of equipment problems; pCi/mL, picocurie per milliliter; pCi/L, picocurie per liter; SL, sample lost in analysis; USGS, U.S. Geological Survey. Symbol: ±, plus or minus]
