Satilla Riverkeeper and a team of dedicated volunteers conduct water quality sampling at numerous public landings on the Satilla River Water Trail. During the summer months, water quality samples are taken every 2 weeks. The most recent testing took place within the last 30 days. The data is also recorded at the GaEPD Adopt A Stream website https://adoptastream.georgia.gov/ as well as at SwimGuide. Please reach out if you have questions or concerns.
One of the parameters volunteers test is bacteria. The concentration of Escherichia coli (E. coli), a species of coliform bacteria found in the gastrointestinal tract and feces of mammals, can be an indicator of the presence of other harmful bacteria or pathogens in the water. All of the public landings tested within the last 30 days showed E. coli levels within the safe limits according to EPA guidelines for swimming areas with the exception of Waverly Creek in Camden County.
Why look specifically for E. coli?
E. coli acts as an indicator species. If significant amounts of E. coli are found, there are most likely other bacteria such as disease-causing bacteria and viruses. However, this is not always the case. Just because there are colonies of E. coli found in the water does not mean that there are always the other harmful bacteria and viruses present. And vice versa, just because E. coli isn’t detected, it does not mean that the waterways are always safe. There is, however, a proven positive correlation with high levels of E. coli and illness and infection.
