Help Galveston Bay thrive one drop at a time

As a Water Monitoring Team volunteer, you become an member of a community-powered effort to protect the waters of Galveston Bay.

Each month, you’ll gather essential data (e.g. temperature, oxygen levels, salinity) that helps scientists, neighbors, and decision-makers understand how our Bay is doing. Your hands-on role contributes to real-time tools like SwimGuide.org. By making invisible water quality issues visible through concrete data collection, your work can inform collective action that builds a resilient, thriving Bay for generations to come.

Below are the steps towards becoming a GBF Water Quality Monitor:

  • Agree to make a 2-year commitment to sample one a month at your assigned site.
  • Attend a one-day training session with GBF or attend a training with a Texas Stream Team partner (e.g., Texas Stream Team, HGAC, Bayou Preservation Association).
  • Before registering for a training session, make sure that there is a sample location you would be interested in sampling. See available sites below.
  • Complete a one-on-one certification session with the Water Protection Team. The time on this training event varies between 2-4 hours. View upcoming trainings on our Events page.
