Floodplain Pilot Study Update — Carbon Amendment of Floodplain Soil (AOC 4, Former DuPont Waynesboro Site)

Slide presentation (Aug 18, 2015) reporting a field pilot testing carbon (biochar) amendments to floodplain soils at AOC 4 (Former DuPont Waynesboro site). Objectives: evaluate effectiveness at reducing methylmercury production and potential unintended effects. Methods include in situ mesocosms with 5% and 10% biochar, soil geochemistry/redox monitoring, and earthworm survivability and Hg bioaccumulation; sampling ongoing.
