Overview of  Water Quality Parameters

Texas Stream Team citizen scientists who have competed a Core training collect data on various Core water quality parameters to assist communities, government agencies, businesses and industries, and educational organizations in promoting informed natural resource management decisions. These parameters are:

  • Water and Air Temperature
  • pH
  • Dissolved Oxygen (DO)
  • Total Dissolved Solids and Conductivity
  • Water Clarity
  • Field Observations

Texas Stream Team citizen scientists who completed the Advanced training collect data on additional water quality parameters, such as:

  • E. Coli Bacteria
  • Nitrate-Nitrogen
  • Orthophosphate
  • Water Turbidity
  • Streamflow

Citizen Scientists submit their data to the Texas Stream Team program directly or through their designated Texas Stream Team partner organization. All monitoring forms are reviewed upon entry to assure the data meets the requirements set by an approved Quality Assurance Protection Plan (QAPP).

All data that meets the requirements of the QAPP are sent to the Texas Commission on Environmental Quality (TCEQ) database to be used as a supplement to professionally collected data. TCEQ uses of approved Texas Stream Tea, data include:

  • Comparison with Water Quality Standards
  • Trend Analyses
  • Identifying Water Quality Conditions and Concerns Requiring TCEQ Action
  • Use as Baseline Information in the Total Maximum Daily Load (TMDL) Development Process

All Texas Stream Team citizen scientist data are available to the public via the Datamap.

Quality Assurance Project Plan (QAPP)

A QAPP outlines the procedures a monitoring project uses to ensure that all samples and data are of high enough quality to meet program standards. By adhering to these procedures, Texas Stream Team program personnel and citizen scientists ensure QAPP-approved data can be used for functions including educational purposes, research, best management practice effectiveness, and any other uses deemed appropriate by resource managers and TCEQ.

  • The 2017 QAPP can be downloaded here
  • The 2018 QAPP can be downloaded here.
