<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 cetain standards of water use.
<br /> 3. Metal and radionuclide levels are reported as total recoverable.
