Slide presentation reporting results from sediment coring in the South River to characterize total mercury and methylmercury. It describes sampling locations, core-specific Hg profiles, and use of Cs-137 and Pb-210 isotope dating. Findings indicate historic mercury releases (pre-1960s), elevated surficial Hg (about 5–10 ppm), and estimated sedimentation rates of ~0.4–1.5 cm/yr.
