Impacts of Waynesboro Wastewater Treatment Plant Upgrades on South River: 1-yr Update (October 12, 2011)

Slide presentation (Oct 12, 2011) summarizing a one-year post-upgrade study of the Waynesboro WWTP effects on the South River. Describes monitoring design, nutrient reductions in effluent and river, periphyton colonization and biomass, and methylmercury concentrations in algae. Concludes upgrades greatly reduced effluent nutrients and downstream phosphorus, with limited periphyton response and possible reduced methylmercury uptake after normalization.
