Texas Bacterial Source Tracking Program

Bacteria is the No. 1 pollutant of Texas water bodies, with 255 water bodies failing to meet water quality standards because of bacteria.

Bacterial source tracking (BST) is a valuable tool that can identify, and also rule-out, significant sources of E. coli pollution in a watershed. Using DNA fingerprints and bacterial markers, fecal pollution sources are identified by comparing E. coli DNA to those in a statewide library of known sources.

Bacterial source tracking can:

  • Identify primary sources of E. coli
  • Illustrate the relative abundance of E. coli from identified sources
  • Determine the presence or absence of major watershed sources
  • Inform watershed management decisions
  • Allow resources to be used wisely and focused where pollutant reductions are needed most

The Texas Bacterial Source Tracking Program is a joint program of the Texas Water Resources Institute, Texas A&M AgriLife Research and The University of Texas Health Science Center at Houston (UTHealth) School of Public Health in El Paso.

Our BST program can provide:

  • Timely results
  • Thorough quality assurance and control standards
  • Easy to understand presentation and interpretation of results
