Title: Application of ground water tracer methods in straddle packer testing at the ICPP, INEL

Abstract

The State Oversight Program's straddle packer sampling system was tested at the Idaho National Engineering Laboratory during July--September, 1992, in USGS monitoring well No. 44. The straddle packer was designed for the Oversight Program's ground water research program, to provide a means of characterizing the vertical hydraulic and water quality variations believed to exist in the eastern Snake River Plain aquifer beneath the Idaho National Engineering Laboratory. During the field program, tracer introduction and recovery experiments were conducted to evaluate QA sampling objectives as well as to assess the feasibility of obtaining additional information on aquifer/borehole characteristics such as specific discharge through different aquifer zones, integrity of packer seals, etc. A total of twelve tracer tests were performed on six different intervals from 467 to 600 feet below land surface (ft bls). Lithium bromide powder dissolved in de-ionized water was used as a tracer. All tracer tests were conducted in two phases: Emplacement -- introduction of a slug of a known quantity of tracer, followed by continuous mixing within the test interval for periods ranging from 8 to 72 minutes (without pumping to surface), during which time the tracer was diluted by ground water advection through the test interval; andmore » recovery - pumping of the test interval to withdraw tracer from the borehole interval and the adjacent aquifer. Once tracer recovery had been completed, water quality sampling could be initiated, with the degree of interval purging having been defined by the degree of tracer recovery.« less
