The Rocky Mountain 1 (RM1) underground coal gasification (UCG) test was conducted from November 16, 1987, through February 26, 1988 at a site approximately one mile south of Hanna, Wyoming. The test consisted of a dual-module operation to evaluate the controlled retracting injection point (CRIP) technology, the elongated linked well (ELW) technology, and the interaction of closely spaced modules operating simultaneously. The test caused two cavities to form in the Hanna No. 1 coal seam and associated overburden. The Hanna No. 1 coal seam was approximately 30 ft thick and lay at depths between 350 and 365 ft below the surface in the test area. The coal seam was overlain by sandstones, siltstones, and claystones deposited by various fluvial environments. The groundwater monitoring was designed to satisfy the requirements of the Wyoming Department of Environmental Quality (WDEQ) in addition to providing research data toward the development of UCG technology that minimizes environmental impacts. Further background material and the sampling and analytical procedures associated with the sampling task are described in the Rocky Mountain 1 Postburn Groundwater Monitoring Quality Assurance Plan (Mason and Johnson 1988).
