EPA Water Standards (h)
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 levels are reported as dissolved and radionuclide levels are reported as total recoverable.
