Notes:
1. Water standards are provided for reference only. These standards do not apply to the spring water unless it is used for drinking water, irrigation, or other regulated
uses.
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.
