| Long description: |
The United States EPA has released a new web-based tool, the Causal Analysis/Diagnosis Decision Information System (CADDIS), which simplifies determining the cause of contamination in impaired rivers, streams and estuaries, a water body that does not meet the state or federal water quality standards for one or more pollutants.
There are many possible sources of pollution such as industrial waste, municipal sewage, agricultural runoff, naturally occurring minerals in rock and sand, and biological materials. Before restorative or remedial actions can be taken, the cause of impairment must be determined.
CADDIS provides a standardized and easily accessible system to help scientists find, use and share information to determine the causes of aquatic impairment. Causal analyses look at stressor-response relationships, meaning the effect of a specific substance or activity on the environment, such as excess fine sediments, nutrients, or toxic substances.
This version of CADDIS is the first of three. Future versions will include modules to quantify stressor-response relationships, and databases and syntheses of relevant literature on sediments and toxic metals. CADDIS is available on theEPA Website: http://www.epa.gov/caddis
