U.S. Clean Water Act: relevant ecological issues.
http://5bio5.blogspot.com/2013/10/us-clean-water-act-relevant-ecological.html

The United States Clean Water Act (CWA; 1972, and as amended, U.S. Code title 33, sections 1251-1387) provides the long-term, national objective to "restore and maintain the ... biological integrity of the Nation's waters" (section 1251). 

However, the Act does not define the ecological components, or attributes, that constitute biological integrity nor does it recommend scientific methods to measure the condition of aquatic biota (Davies SP, Jackson. 2006)

The concept of biological integrity is associated with the health of aquatic ecosystem, and activity of aquatic organisms in the water ecosystem. Relevant aspects of activity of aquatic organisms were innovatively analyzed in the recommended publications:
