Table 6. Strontium-90 concentrations in water from selected wells at and near the Idaho Nuclear Technology and Engineering Center, Idaho National Laboratory, Idaho, 1980–2005.

[Well No.: Well locations are shown in figures 5 and 6. Concentrations and associated uncertainties in picocuries per liter. 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 greater than the reporting level. Abbreviations: QA, quality-assurance replicate. NSM, not sampled, well down for maintenance; USGS, U.S. Geological Survey. Symbols: ±, plus or minus; –, no data, well drilled in 1984]
