The Water Monitoring Team collects valuable water quality data including bacteria concentrations around the Bay. The most recent bacteria concentrations for each location are recorded on the Bacteria Results Map below.
Is My Water Swimmable?
Water Monitoring Team volunteers who are specially certified as Bacteria Samplers collect a small amount of water to be tested for a type of fecal indicator bacteria (Enterococcus). Testing is completed at the Galveston Bay Foundation’s Bacteria Monitoring Lab by a specially trained volunteer and GBF staff. To learn more about why this bacteria is tested, visit our Bacteria Reduction Plan webpage.
Each site that has been monitored for bacteria concentrations is indicated by a colored dot on the Bacteria Results Map below.
- Green indicates sites that have a low concentration of bacteria (below 35 CFU/100mL) at the most recent sampling event
- Yellow indicates sites that have a medium concentration of bacteria (between 35 and 104 CFU/100mL) at the most recent sampling event
- Red indicates sites that have a high concentration of bacteria (above 104 CFU/100mL) at the most recent sampling event and are considered unsafe for swimming.
Each summer, GBF hosts two water quality interns for 12 weeks. The interns are responsible for sampling, analyzing results, and presenting the findings at summer’s end. Take a look at what our interns have created! To learn more about our summer internships, check out the Water Quality Internships page!
