Internal Phosphorus Load Reduction with Iron Filings
Internal loading of phosphorus from the lake sediments is a difficult problem to solve in lakes. This research addresses some of the key sediment chemistry questions related to phosphorus, iron and sulfate/sulfide dynamics for lake management, and will target innovative actions to solve this internal loading problem. Our objectives are to determine the effectiveness of iron augmentation in accomplishing the goal of reducing the internal loading of phosphorus in lakes. The results of the research could lead to an ecologically sound tool that effectively addresses the major water quality issue in lakes.
