Abstract |
This report contains conceptual methods and models to guide research on and development of tools for diagnosing the causes of biological impairment within the aquatic ecosystems of the United States. It was produced to satisfy requirements in the U.S. Environmental Protection Agency Aquatic Stressors Framework (USEPA 2002b). The goal of the National Health and Environmental Effects Research Laboratory's (NHEERL) Diagnostics Research Program is (1) to provide tools to diagnose the causes of biological impairment in aquatic ecosystems, (2) to develop a classification system that simplifies the process of developing Total Maximum Daily Loads (TMDLs) or other regulatory programs for the myriad of water bodies requiring them, and (3) to support the States and Tribes in determining the causes of impairment of water bodies to be placed on their 303(d) lists. To accomplish these goals, NHEERL convened a Diagnostic Research Workgroup. This workgroup developed an overview conceptual model of the factors controlling the action of pollutants and detailed conceptual models for four aquatic stressors: nutrients, suspended and bedded sediments, toxic chemicals and altered habitat that were identified as the stressors of major concern in the Aquatic Stressors Framework. |
