Environmental impact of coal ash on tributary streams and nearshore water of Lake Erie. Progress report, June 1, 1975--December 31, 1975. [Cd, Zn, Cu, Cr, Fe, Mn]
The principal study site is the landfill of the Niagara Mohawk Power Corp., Dunkirk, N.Y. Concentrations of dissolved metals are determined in the waters from the site and aquatic invertebrates from ponds and streams at the site are being identified and analyzed for trace metals. Elevated levels of Fe and Mn occur in the runoff from the site and in the aquatic invertebrates. The metals Cd, Zn, Cu, and Cr are found at low levels (ppB range) in the waters and in variable, generally low concentrations in the biota. Taxonomic study is focused primarily on the Chironomidae (10 general) and Ephemeroptera (6 genera) with detailed studies in progress. The rate of leaching of metals from coal ash is also being studied in the laboratory by two methods. Sediments from Lake Erie at Dunkirk, N.Y., are being assessed for textural classification and composition. Attempts are being made to distinguish between coal wastes and other sediment in the silt and finer size range. The dump site is being evaluated for groundwater, surface water, and geological structure, so that trace element cycling can be evaluated.
