Improving Austin Streams Presented to the North University NA December 2, 2013 Chris Herrington, PE
Potential presence of fecal contamination measured with indicator bacteria E. coli
E. coli as a fecal indicator • Contact Recreation Standard set by Texas Commission on Environmental Quality • Measure potential for fecal contamination, not actual presence of pathogens • Long-term measure of conditions, not an assessment of human risk
Taylor Slough South Spicewood Trib to Shoal Waller Creek (upstream of 15th) Walnut Creek
Sources of Fecal Contamination • Domestic animals (dogs, cats, chickens) • Leaking wastewater infrastructure • Wildlife (deer, bird, racoon, etc.) • Humans defecating in creeks • Failing homeowner septic tanks
How to reduce fecal bacteria Working with TCEQ, diverse group of stakeholders to develop a 5-year plan that addresses: • Domestic pet waste via public education • Wastewater infrastructure maintenance • Stormwater treatment • Riparian zone restoration
