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 <br />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 <br />compared to certain standards of water use. <br />3. Metal and radionuclide levels are reported as total recoverable. <br />Table 4 Water Quality Data <br />Lumsden Canyon Seep <br />Page 2 of 2 <br />
