Support Analytical Infrastructure and Further Development of a Statewide Bacterial Source Tracking Library

G. Di Giovanni, E. Casarez, T. Gentry, E. Martin, L. Gregory, K. Wagner

The project titled Support Analytical Infrastructure and Further Development of a Statewide Bacterial Source Tracking Library funded by the Texas State Soil and Water Conservation Board was established to provide needed resources to expand the application and utility of bacterial source tracking (BST) while simultaneously advancing the science of BST. In some form, BST has been applied in Texas for more than a decade; however, method differences, inconsistent approaches, and limited geographical coverage of the Texas E. coli BST Library have caused concern over the applicability of BST results between watersheds. Corollary to these concerns is a general lack of readily available information on the subject. Subsequently, the applicability and utility of BST are often misunderstood. Additionally, the formation of the Bacteria Total Maximum Daily Load (TMDL) Task Force and the recommendations it produced outlined needed advancements in BST research and development. This project was established to allay these concerns by focusing on increasing application, capacity and coverage of BST resources available in the state and to accomplish several of the recommended research and development needs.
