These standards do not apply to the site groundwater unless it is used for drinking water, irrigation, or other regulated uses. <br /> 2. Concentrations or activity levels above a state or federal standards are shaded for reference purposes. Shading indicates that the measured level is elevated compared to certain <br /> 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 1 of 2 <br />
