WWALS Summary of FDEP chemical and biological tracers, Withlacoochee and Suwannee Rivers 2020-08-05

Here are the chemical tracer and DNA marker test results by the Florida Department of Environmental Protection (FDEP) that WWALS has frequently mentioned, for example in Current Situation of Water Quality Testing, Suwannee River Basin 2020-08-02.

Below, please also find a summary of those results by WWALS Science Committee Chair Dr. Thomas Potter.

Thanks to Katrina Yancey of FDEP for sending the data, and for acknowledging that FDEP has no objection to WWALS publishing it. I asked FDEP for whatever they wanted to include, and this is what they sent:

“Thank you for asking, we recently set up our new site so it may be helpful to state that more information may be found at DEP’s webpage for the Suwannee River Basin Sampling Locations (https://floridadep.gov/dear/watershed-monitoring-section/content/suwannee-river-basin-sampling-locations).”

The actual data is on the WWALS website.

Waterkeepers Florida met FDEP in Orlando about Triennial Review of Water Quality Standards 2019-04-15

FDEP is analyzing DNA and human tracers such as sucralose monthly at at least three stations: on the Withlacoochee and Alapahoochee Rivers at the Georgia-Florida line, and at the Withlacoochee River Confluence with the Suwannee River at Ellaville. This is what Waterkeepers Florida (WKFL) heard in Orlando on April 15th from FDEP’s Tom Frick. I think he may have also said at the Alapaha Confluence with the Suwannee River.
