William Kenney has specialized in the use of nutrient chemistry (carbon, nitrogen, phosphorus, and silica) in the evaluation of anthropogenic impacts on aquatic ecosystems.  His work includes studies of water column processes and sediment biogeochemistry.  Water column studies focus on the impacts of anthropogenic nutrient loads on primary production and primary producer community structure in shallow Florida lakes.  He uses biogeochemical and radiometric analyses of sediment core samples to investigate the long-term influence of nutrient enrichment on lakes.
