The Clean Watersheds Needs Survey (CWNS) is
a comprehensive assessment of needs to meet
the water quality and water- related public health
goals of the Clean Water Act (CWA). States and
the U.S. Environmental Protection Agency (EPA)
conduct the CWNS every four years under CWA
Section 516 (b). Alaska did not participate in the
2004 and 2008 Surveys.
