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.

Subaru featured Tom Potter for science, cleanup, outings, and water quality

“If you get people out on the river and they have a positive experience with nature, they will help protect it,” wrote Dr. Tom Potter, pictured during the March 2019 Onemile Branch Cleanup at Drexel Park during Azalea Festival.

Fragility of monoculture agriculture in varying water conditions

They don’t want to say “we don’t know,” but they don’t know. At least they have a working hypothesis about the collapse of the 2017 peanut crop in much of Florida: it has to do with variations in rainfall.

Bob Kemerait, Southeast Farm Press, 22 January 2018, Peanut collapse: Something happened but it’s not clear exactly why,

…For months, University of Florida’s Institute of Food and Agricultural Sciences Extension agents led by Anthony Drew, Mace Bauer and Dee Broughton had been sounding the alarm that an unprecedented collapse of the peanut crop was occurring across large areas of Florida’s production region. Symptoms of this collapse included stunted plants, late-season yellowing and leaves with distinctive marginal leaf necrosis. Where most severe, entire fields wilted in the weeks prior to harvest. Abysmal yields, off by as much as 45 percent, forced some to consider their future in farming if solution could not be found.

During the latter third of the season, Continue reading

Pesticide dust blew across the road between the Withlacoochee and Suwannee Rivers just the other day:

Nearby resident and WWALS member Brit McClung says:

“A good portion the chemicals that are applied to that field wind up on my front porch, on me and in my lungs with the dirt.”

His land is just northeast and a church is southeast of Continue reading

Agricultural land bought by west coast investors

Investment firms owned by Bill Gates have bought thousands of acress of agricultural land in counties in or near WWALS watersheds in south Georgia and north Florida, all above the Floridan Aquifer, near the Alapaha, Alapahoochee, Withlacoochee, and Suwannee Rivers, as part of a nationwide buying spree of a quarter million acres.

Here’s a summary of what we’ve found thus far. Any more recent posts should be found through this search.

These purchases of hundreds and thousands of contiguous acres are all after Bill Gates announced in 2012 he was going to “fix” agriculture in conjunction with Monsanto and Syngenta.

And it’s not just Bill Gates. Continue reading

THE FLORIDAN AQUIFER

by Sandra McCullough
Sandra McCullough lives in Valdosta, Georgia. She is a Speech Communications major and has an interest in the Environment and Humankind’s interaction with the Environment. Sandra plans to continue her education and become a teacher of public speaking. The topic to be discussed here is the Floridan Aquifer.

The Floridan aquifer system is very important to a large number of people, despite general lack of knowledge of or about it. The Floridan aquifer underlies all of Florida, south Georgia, and parts of both Alabama and South Carolina.’ This particular aquifer system is one of the major sources of ground-water in the United States. For this reason and more, studies of its function have been done for years. These studies as well as other findings will be discussed in this paper.
