Texas Stream Team …is a joint partnership with Texas Commission on Environmental Quality, U.S. EPA Region VI, Texas State University-San Marcos, and numerous partners. PREPARED IN COOPERATION WITH THE Texas Commission on Environmental Quality and U.S. EPA. The preparation of this presentation was financed through grants from the Texas Commission on Environmental Quality

Watershed Education Water Quality Monitoring Stakeholder Engagement and Community Action
3
General Initiatives Watershed education and Targeted curriculum resources –Bacteria and sediment modules –Data analysis, monitoring manual modules Monitoring –pH, D.O., TDS, temperature, flow severity, etc –E. coli Web site resources Materials - Maps, Watershed Models Partner collaboration Intensive bacteria surveys
4
A Watershed… …is the area in which water, sediments, and pollutants drain into a common body of water Everyone lives in a watershed

Land Uses and Pollution in Your Watershed…

Arroyo Colorado Watershed
10
Pollution Sources
11
Point and Nonpoint Source Pollution Point Source: factory pipes and wastewater effluent Nonpoint Source: fertilizers; cow manure from a cattle ranch; or a parking lot dotted with oil from cars
13
All data is collected within a TCEQ approved QAPP. Data intended to be used for problem identification, education, research, and local decision making.
15
Integrity of Water Chemical Variables Biotic Factors Energy Source Flow Regime Habitat Structure
16
Integrity of Water
17
Flow Increases in pathogens and other pollutants often positively correlate with increases in the hydrograph.
18
Integrity of Water
20
Algal and aquatic plant growth is stimulated by high levels of nutrients. …often introduced by runoff containing high concentrations of nitrogen and phosphorus.

24
Temperature Biological, chemical, and physical processes are influenced by temperature. Examples: D.O. as T Conductivity as T Neutral pH as T
25
Dissolved Oxygen …measures amount of oxygen dissolved in the water (in ppm or mg/L) Why is it important? How does O2 get into the water? How does O2 leave the water? Acceptable Ranges Chemical properties
26
Conductivity …measures rate at which electrical current passes through water Why is it important? What impacts conductivity?
27
pH …measures hydrogen ion concentration 0-14 scale Natural buffering capacity Impacted by natural and human factors
28
Integrity of Water
29
Is the water safe to swim in? Is the water safe for fish? Can we eat the fish? Can we drink this water if it is treated first? Can I use this water for irrigation? Can I use this water for my industry? CONTACT RECREATION AQUATIC LIFE USE FISH CONSUMPTION DRINKING WATER FOOD PRODUCTION BUSINESS
30
Is the water safe to swim in?
31
Are Contact Recreation Standards Important to YOU?
33
Bacterial Indicators …like fecal coliform or E.coli …like fecal coliform or E.coli are called indicators because their presence indicates the possibility that disease causing pathogens are present. are called indicators because their presence indicates the possibility that disease causing pathogens are present.
34
Contact Recreation Criteria TCEQ Standards for “single grab” samples: Fecal coliform – less than 400 colonies/100mL E.coli – less than 394 colonies/100mL
35
Dark blue to purple are E.coli
36
How can citizen monitors bring capacity to restoration efforts? 925 water bodies surveyed for the 2008 report
