Environmental performance assessment of coal ash use sites: Little Canada structural ash fill
- Radian Corp., Austin, TX (USA)
In 1987, EPRI initiated the Waste Use Environmental Effects Study (RP-2796) project, aimed at evaluating the long-term changes in soils, vegetation, and groundwater quality around ash embankments, structural fills, road beds, and soil amendment areas where coal combustion residues have been utilized. As part of the initial (Phase 1) research, field investigations were conducted at a structural ash fill in Little Canada, Minnesota. The site contained about 39,000 cubic meters of Type C coal ash from nearby coal-fired electrical generating stations owned by Northern States Power Company. Field investigations conducted in 1987 and 1988 included installation of 30 groundwater monitoring wells, 12 porous cup lysimeters, and two glass-brick lysimeters and sample collection on two occasions. Groundwater, soils, and vegetation samples were also collected. Results are discussed. 57 refs., 23 figs., 15 tabs.
