Excess phosphorus (P) is a major pollutant in aquatic systems. Phosphorus removal structures, landscape-scale filters designed to capture dissolved P from runoff, drainage, and wastewater offer promise curbing pollution. While the environmental benefits of various structures are well documented, cost-effectiveness each structure's ability sequester lacking. In this study, we compare most prominent structures. Specifically, calculate average cost per kilogram (kg) removed by eight different across range parameter assumptions. Absent constraints, found that (1) larger use (2) regionally available sorption materials (3) byproducts industrial production (e.g., metal shavings steel slag) rather than manufactured more cost-effective. The for varies $100 1300 kg our baseline estimations, which comparable treatment. This work provides further information guide optimal implementation conservationists.
