Comments

HFBR Pump and recharge ran 1999-2000 and was restarted in November 2007. This system is expected to finish operating in 2011
and meet standards by 2030. Remediation objectives are to meet MCLs standards in groundwater; complete cleanup of
groundwater in a timely manner (30years or less for Upper Glacial Aquifer) and prevent or minimize further migration. Basis for
exit strategy: Reach MCLs in 30 years. Expected period of performance: Up to 20 years for MNA portion. Remedy of combined
hydraulic control, radiological decay, and MNA will restore aquifer.
