【 摘 要 】

Nine new CERCLA groundwater monitoring wells were installed in the 300-FF-5 Operable Unit in calendar year 2006 to fulfill commitments for the EM-20 funded polyphosphate treatability test. Nine new performance monitoring wells were drilled into the uppermost unconfined aquifer, to the Hanford formation - Ringold Formation contact boundary, and completed within the permeable Hanford fm. unit 1 gravel-dominated sequence. The overall objective of the polyphosphate treatability test is to evaluate the efficacy of using polyphosphate injections to treat 300 Area uranium contaminated groundwater in situ. The objective of this work was to install the performance monitoring network surrounding the existing treatability injection well C5000 (399-1-23) in support of the implementation of a field scale demonstration of the polyphosphate technology.
