Phosphorous Trading

In order to improve and preserve water quality, nutrient trading will have to play a significant role in obtaining cost-effective reductions. Research is being conducted to develop an effective point-nonpoint source pollutant trading program for total phosphorus in New Jersey that is both scientifically and economically feasible. The trading program will reduce pollutants because total amounts will be limited to meet the Total Maximum Daily Loads (TMDLs) of phosphorous. TMDLs establish the amount of pollution a water body can receive and still meet water quality standards. A study to develop and implement a phosphorous trading program in the Upper Passaic River Watershed was funded by a grant from the U.S. Environmental Protection Agency Targeted Watersheds Grant Program. In addition to economic benefits, this program will provide opportunities for wetland restoration and improved wildlife habitats. Collaborators include Cornell University, the New Jersey Department of Environmental Protection and the Passaic River Alliance.
