Impact/Purpose:
Develop sampling protocols and a comprehensive database to field test developmental, predictive TMDL models. These protocols and models will then be applied for calculating TMDLs.
Description:
This technical report provides a description of the field project design, quality control, the sampling protocols and analysis methodology used, and standard operating procedures for the South Fork Broad River Watershed (SFBR) Total Maximum Daily Load (TMDL) project. This watershed is located in the Savannah River Basin and the project constitutes Task 12556, Field Research Program. A TMDL is the sum of the individual pollutant waste load allocation for point sources and load allocation for nonpoint sources and natural background, with a margin of safety (CWA Section 303 (d)(1)(C), EPA 1999). The field study reported was part of a project designed to develop sampling protocols and predictive models, and to establish a comprehensive database to field test the developed models in a field setting not available elsewhere in the U.S. The protocols and models will then be applied to calculate a series of TMDLs for contaminants of concern (e.g. sediment, nutrients and pathogens). These protocols can be used by the EPA Regions, Office of Water, and States to meet the national requirements for TMDL development and implementation under the Clean Water Act. The field study will establish scientific basis for clean sediment and pollutant TMDLs.
