"The West Fork of the Black River lies in a bicarbonate dominated river system which runs through Missouri's actively-mined New Lead Belt. Water chemistry, sediment composition, particle size distribution, mineral speciation, and stream flow data were evaluated to characterize lead and zinc transport processes during varying hydraulic events. Water and sediment samples were taken and analyzed quarterly at six sites along the West Fork for seven separate time periods. Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) data for unfiltered water samples collected during normal flow conditions showed maximum lead and zinc concentrations of 6.7 µg/L and 163 µg/L, respectively. Lead concentrations were below the EPA Drinking Water Action Level for Pb (15 µg/L) except for two unfiltered samples taken during storm flow which had lead concentrations of 65 and 21 µg/L. Lead concentrations showed no relation to flow while zinc concentrations generally increased with increasing flow. Sediment samples showed a wide range of lead and zinc concentrations (3-960 ppm Pb and 4-2488 ppm Zn). Optical microscopy and Scanning Electron Microscopy (SEM) analyses of sediment samples indicated that metals were incorporated in manganese and iron oxyhydroxide minerals and coatings on sediment grains. Metal sulfides were not found in any sediment samples"--Abstract, page iv.
