Texas Bacterial Source Tracking Program FY16–FY17

Project Goals and Objectives: Bacteria are the number one cause of water quality impairment in Texas. Bacterial Source Tracking (BST) is a valuable tool for identifying human and animal sources of fecal pollution to support development of watershed plans, TMDLs, and other strategies for addressing these impairments. Comprehensive BST has been completed by UTSPH EP and Texas A&M AgriLife SCSC in numerous watersheds throughout Texas with support provided by the TSSWCB. As a result of these joint efforts over the last decade, the Texas E. coli BST Library (ver. 5-15) currently contains 1,765 E. coli isolates obtained from 1,554 different domestic sewage, wildlife, livestock and pet fecal samples. Despite its expansiveness, continued development and refinement of the library to include additional known source isolates from additional Texas watersheds and different animal hosts is needed to further increase its utility.

Other project goals include:

  • Support BST analyses throughout Texas
  • Further refine Texas E. coli BST Library
  • Evaluate new library independent markers
  • Provide outreach regarding BST

Project Location: Statewide, Plum Creek in Caldwell, Hays and Travis Counties and Big Elm Creek in Bell County

Project Cost: State Funds ($444,170)

Project Participants: TSSWCB, Texas Water Resources Institute (TWRI), University of Texas Health Science Center at Houston School of Public Health El Paso Regional Campus (UTSPH EP), Texas A&M AgriLife Research-Department of Soil and Crop Sciences (AgriLife SCSC)
