Two constructed wetlands demonstration projects in the Imperial Valley of California are being designed to help improve the water quality of the New River, which originates in Mexico and dumps into the troubled Salton Sea. The 68 ac (28 ha) Imperial wetlands project will treat agricultural drain water from the Imperial Valley before it reaches the New River. The 7 ac (3 ha) Brawley wetlands site will treat water directly from the river, whose flow is made up of agricultural drain water, industrial discharges, and untreated wastewater from Mexico. If a three-year monitoring effort depicts promising results, the $3-million project could be expanded in the future.
