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
