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. <br />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 <br />certain standards of water use. <br />3. Metal levels are reported as dissolved and radionuclide levels are reported as total recoverable. <br />Table 3 Water Quality Data <br />Monitoring Well W-1 <br />Page 2 of 2
