Salinity-Colorado River Water Quality Crisis

by David B. Mason, Sr., U.S. Department of Agriculture, Washington, United States,

Document Type: Proceeding Paper

Part of: Coastal Zone '93


The major concern cited is excessive salt concentrations caused by salt loading of return flows to the Colorado River. Salinity levels measured as milligrams per liter (mg/L) are monitored closely to ascertain if the United States is maintaining water quality standards established by the seven Basin states and approved by the Environmental Protection Agency (EPA). Title II of the Colorado River Basin Salinity Control Act is concerned specifically with implementing measures upstream from Imperial Dam to comply with the salinity standards. USDI, USDA and EPA are directed by Title II of this Act to coordinate their activities to carry out the objectives of this Title.
