South River Mercury TMDL — June 2005

Slide deck from a USGS presentation describing a South River Mercury TMDL study. It outlines goals to characterize total and methyl mercury cycling, develop flow and methylation models, and determine load reductions to meet fish tissue targets (<0.5 ppm). Slides summarize monitoring sites (Waynesboro, Dooms, Harriston), sampling plans, early continuous pH/turbidity and streamflow data (May 2005), and planned next steps.
