Changes in phosphorus loading in the Sunrise River Watershed from Projected Population increases

Document
Description
The loading of phosphorus from our lands to our water resources is commonly the single largest cause of eutrophication, where excess algal growth degrades water quality. Population growth will change phosphorus loads (a) by changing point-sources loads released by waste-water treatment plants and (b) by changing nonpoint-sources loads from different land uses. Future point-source loads were estimated by assuming current waste-water treatment efficiencies (kg phosphorus per capita served) applied to projected populations. To estimate nonpoint sources of phosphorus, a computerized watershed model was constructed for the Sunrise River watershed by using the Soil and Water Assessment Tool (SWAT).
