Proposal for Alluvial Groundwater Study

Slide presentation (N.R. Grosso, DuPont) outlining a proposed study to evaluate whether alluvial groundwater discharging to the South River is a diffuse source of dissolved mercury. It describes objectives, prior soil Hg data, groundwater flow regimes, proposed scouting (hydropunch) and well installation, potential well locations, and next steps including statistical review and workplan preparation.
