Abstract
The geology, water movement, and sediment characteristics in the upstream part of the Spring River basin have been appraised, to assist the U.S. EPA in their study of dioxin contamination in the area. The U.S. Environmental Protection Agency has confirmed that the dioxin compound, TCDD (2,3,7 ,8-tetrachlorodibenzo-p-dioxin), is present in the soils, streambed sediments, and fish in the upstream part of the Spring River Basin. Although the solubility of dioxin is small, it may be moving through the hydrologic system, adsorbed on sediment particles. Water movement in the shallow aquifer generally follows the topography. In upland areas, precipitation recharges the shallow aquifer, then the shallow aquifer water discharges into larger streams. Sediment yields generally are small in the upstream part of the Spring River basin. Suspended sediment discharges for the Spring River at La Russell ranged from 3.0 tons/day at a flow of 79 cu ft/sec, 1.7 times the 7-day 2-yr low flow, to about 1240 tons/day at a flow of 1600 cu ft/sec, 6.7 times the long-term average. Suspended sediment particles in the Spring River and Honey Creek generally were silt and clay (smaller than 0.062 mm). Fine sediments with adsorbed dioxin may be transported out of the area by streamflow, or they may be deposited on flood plains or in downstream impoundments during periods of flooding. (Lantz-PTT)
