Geochemical and hydrological controls on the release of phosphorus from legacy storage zones in agricultural stream corridors

Excessive phosphorus pollution from anthropogenic activities causes surface water eutrophication, which can lead to nuisance and harmful algae blooms. The subsequent degradation of aquatic ecosystems and contamination of drinking water sources has severe economic and environmental consequences. While considerable conservation measures have been put to reduce phosphorus pollution, soluble reactive phosphorus (SRP), the bioavailable form of P that is taken up by plants, are continuing to increase despite phosphorus reduction efforts. Recent studies indicated legacy phosphorus storage in riparian zones and streambed sediments may be released at certain geochemical and hydrological conditions. However, there is a lack of knowledge of the phosphorus release mechanisms and controlling factors. The project aims to develop an improved understanding of the sources and pathways delivering SRP to surface waters by incorporating field investigations, historical database, and contaminant transport models.
