Ecological Risk Assessment

SADA incorporates a number of benchmark databases for conducting screening ecological risk assessments. Ecological benchmarks for over 100 contaminants in surface water, sediment, and soil are included. Capabilities include spatially comparing environmental concentration data to benchmarks for identifying areas and contaminants of concern. For information and screenshots for each media click below:
