Remediation plan for Well 399-1-16C

The purpose of this plan is to determine hydraulic conditions at Well 399-1-16C (16C) and to present a remediation plan. The objectives are to restore hydraulic isolation of the confined aquifer (water level returning to approximately 370 ft) and to prevent chemical contamination between the unconfined and confined aquifers. This work scope is an extension of Task 4d of the Remedial Investigation/Feasibility Study Work Plan for the 300-FF-5 Operable Unit, Hanford Site, Richland, Washington, DOE/RL 89-14 (1990), and is a result of discussions held with the regulators and documented this plan was presented to the regulators at the January 1993 unit managers meeting and is documented in the minutes from that meeting
