(The CADDIS team anticipates this part of the site will expand to include other common stressors and—at some point in the future—harness information collaboratively from the greater scientific community.) • Updated CADDIS’s underlying code, which adheres to EPA’s latest Web guidelines, and—similar to the first release—continues to maintain accessibility and 508 compliance. The CADDIS 2007 release provides users with state-of-the-art causal assessment information and tools for determining why aquatic systems are biologically impaired. Ultimately, use of the CADDIS Web site translates to healthier ecosystems within the United States, while serving as an example stressor identification tool for our global environment.
