The Region 9 Water Division is responsible for providing clean and safe surface water, ground water, and drinking water and protecting and restoring aquatic ecosystems in the Pacific Southwest. We oversee state and tribal implementation of core programs to accomplish these goals.
We encourage use of a watershed approach to protect public health and water resources including lakes, rivers, estuaries, oceans, and wetlands. Primary authority for EPA water programs was established by the 1986 amendments to the Safe Drinking Water Act (SDWA) and the 1987 amendments to the Clean Water Act (CWA).
