Abstract: In a field test at DOE's Hanford reservation in 1995, ~77,000 liters of buffered sodium dithionite solution were injected into the unconfined chromate-contaminated aquifer at the 100-H area to create a permeable treatment zone in the subsurface. The success of the field test led to a proposal to develop a pilot-scale permeable treatment zone in the chromium-contaminated 100-D area using In-Situ Redox Manipulation (ISRM) for remediation of redox-sensitive contaminants in the ground water.

Abstract: Near Chalk River, Ontario, a ground-water plume containing radioactive strontium (90Sr) is to be intercepted and treated with a combination of a Waterloo Barrier cut-off wall, a reactive curtain containing granular clinoptilolite, and a passive tile drain.

Abstract: Pacific Northwest National Laboratory researchers have developed in situ redox manipulation (ISRM) to remediate chromate-contaminated ground water. In testing at Hanford, five ground-water wells were positioned about 500 feet from the Columbia River in a known chromate plume. Sodium dithionite was injected into a well for about 10 hours. Once it reached the ground water, the sodium dithionite reacted with iron in the ground and spread out into a circle about 50 feet in diameter. The five wells created a permeable barrier 150 feet wide for ground water to pass through as it flows toward the river. Targeted contaminants are destroyed or immobilized as the plume crosses the barrier. After about 30 hours, sodium sulfate, a nontoxic byproduct, is removed over a one-week period. The barrier may remain effective for up to 30 years. ISRM uses a standard six-inch ground-water well and does not require building permanent structures.
