GRIFFITH, M. B. Relationships Among Exceedences Of Chemical Criteria Or Guidelines, The Results Of Ambient Toxicity Tests And Community Metrics In Aquatic Ecosystems (Final). U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-06/078.
Impact/Purpose:
The EPA document, Relationships Among Exceedances of Chemical Criteria or Guidelines, the Results of Ambient Toxicity Tests, and Community Metrics in Aquatic Ecosystems, presents two studies where the three general approaches for the ecological assessment of contaminant exposure and effects in surface waters or sediments were applied to stream sites sampled in the Southern Rockies ecoregion of Colorado and to estuarine sites sampled in the Virginian Estuarine Province of the Atlantic coast. This document is intended to be a technical resource for program offices, regions, states, and tribes interested in the application of these methods for evaluating the attainment of aquatic life use in streams and estuaries and for assessing the causes of impairment in affected systems.
