Focus Sheets

Unless otherwise noted, the following focus sheets are located on the Ecology Publications website:

Focus on Cleaning Up Water Pollution
The Clean Water Act established a process to identify polluted waters and clean them up. Every two years, states are required to prepare a list of water bodies that do not meet water quality standards. This list is called the 303(d) list, because the process is described in Section 303(d) of the Clean Water Act.

Focus on Water Quality Standards
An overview of the revisions made by the Washington Department of Ecology, on July 1, 2003, to the state’s surface water quality standards.

Focus on Temperature: Water Quality Standards
Discussion of the importance of water temperature to the health and survival of native fish and aquatic communities.
