Re-injection accelerates groundwater clean up at Fernald, Fluor Fernald, Inc

摘要

A successful one year long, field scale demonstration of the use of groundwaterre-infection at Fernald was recently completed bringing DOE one step closer to achieving an accelerated site remediation (DOE 2000). The demonstration marks the end of a several year effort to evaluate whether: re-injection could be conducted efficiently at Fernald, and if the approved aquifer remedy at Fernald would benefit by incorporating re-infection. Evaluation of re-injection technology involved not only technical considerations, but also participation and cooperation of regulators and stakeholders. The demonstration was considered to be unique in that it was integrated into the design of the current approved aquifer remedy and utilized the existing remediation infrastructure. Information collected during the demonstration indicated that re-injection wells could be operated efficiently at Fernald and that the current approved groundwater remedy should be modified to include the use of re-injection.
