2. Concentrations or activity levels above a state or federal standard are shaded for reference purposes. Shading indicates that the measured level is elevated compared to certain standards of water use.
3. Metal and radionuclide levels are reported as total recoverable.
* Nitrate sample recollected on 9/18/08 due to hold time exceedance on 9/8/08 sample
