Notes:
1. Water standards are provided for reference only. These standards do not apply to the site groundwater unless it is used for drinking water, irrigation, or other
regulated uses.
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 standards of water use.
3. Metal and radionuclide levels are reported as total recoverable.
