Water Quality Parameters
Overview of Parameters
Effective collection and management of water quality data provides volunteers the opportunity to recognize changes in water quality and empowers them to take appropriate action. The Texas Stream Team program promotes the use of volunteer data at the local level, by partners, volunteers, schools, government agencies, business and industry and others, for education and for use in natural resource management decisions.
The water quality parameters that volunteers collect data on are: Water Temperature; pH; Dissolved Oxygen; Total Dissolved Solids and Conductivity; Water Clarity; Field Observations; and E. coli bacteria.
Volunteers submit their data to the Texas Stream Team program directly or through the Texas Stream Team Partner. All monitoring forms are reviewed and entered into the Texas Stream Team database. In addition, data that meet the requirements of the Quality Assurance Program will be sent to the Texas Commission on Environmental Quality (TCEQ) database to be used to support and enhance professionally collected data. The TCEQ will use the quality-assured volunteer data for comparison with water quality standards and in trend analysis, for identification of water quality conditions and concerns requiring TCEQ action, and as baseline information in the Total Maximum Daily Load (TMDL) development process.
Texas Stream Team volunteer data are available to the public through the Texas Stream Team Data Viewer, available here: aqua.meadowscenter.txstate.edu/
Quality Assurance Program
All Texas Stream Team data are collected within an approved quality assurance project plan (QAPP). A QAPP document outlines the procedures a monitoring project will use to ensure that the samples and data are of high enough quality to meet project needs. The goals of the group and Texas Stream Team’s support capabilities determine which plan volunteers are monitoring within. QAPP intended data uses include: education, research, screening and problem identification, Best Management Practice (BMP) effectiveness, and other uses deemed appropriate by resource managers and the TCEQ.
You can contact the Texas Stream Team to learn more about our QAPP by calling 1-877-506-1401 or e-mail firstname.lastname@example.org
