Table 3. Tritium concentrations in water from selected wells at and near the Central Facilities Area and the Idaho Nuclear Technology and Engineering Center, Idaho National Laboratory, Idaho, 1980–2001.

[Well No: Locations of wells are shown in figures 4 and 5. Concentrations and associated uncertainties in picocuries per milliliter. 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. Abbreviations: USGS, U.S. Geological Survey; NS, not sampled. Symbols: ±, plus or minus; –, no data, well drilled in 1984]
