Revised Hydrogeologic Framework of the Floridan Aquifer System 2016-03

Salt water intrusion inland is worse than you think, including the “Apalachicola salinity feature” up to the GA-FL line and east through Lowndes County, with a special additional brackish Valdosta feature. Central north Florida is an island of fresh groundwater surrounded by entire saline Florida coast around from Alabama plus across to Brunswick, GA, then again from Savannah up past Charleston. South of Lakeland, FL the map is all red for saline.

Apparently using the data preliminarily mapped earlier in the Florida Well Salinity Study, geologists from three states connected the dots in Revised Hydrogeologic Framework of the Floridan Aquifer System in Florida and Parts of Georgia, Alabama, and South Carolina, By Continue reading

Videos: Water, Agriculture, and Forestry; WWALS @ VSU 2017-03-28

You can’t use traditional models for the karst Floridan Aquifer; new and harsher pesticides are expected this summer; but you can help raise native species; and later this month you can go see many of them in Berrien County, plus WWALS monthly outings, the Withlacoochee and Little River Water Trail, and the Alapaha River Water Trail and some WWALS history.

Yeah, 2,4-D and Dicamba are head-scratchers --Tom Potter
Yeah, coming this summer, and they’re head-scratchers.

All this was at the quarterly WWALS public meeting, this one on Water, Agriculture, and Forestry at Valdosta State University, March 28, 2017.

Here are links to each WWALS video of each talk, with a few notes and a few extra pictures, followed by a WWALS video playlist. Continue reading

Other aquifer models don’t work for karst Floridan Aquifer –Geology Prof. Can Denizman to Suwannee River Partnership 2017-03-03

Someone said there’s an actual scientist in the room, so let’s hear from him. So WWALS Science Committee member Geology Professor Can Denizman said a few words about modeling karst limestone aquifers such as the Floridan Aquifer. This was at the March 3, 2017 meeting of the new Environmental Advisory Work Group of the Suwannee River Partnership.

Delineation of Spring Protection Areas

These figures tell the story of springsheds in a coastal lowland karst plain such as much of the Suwannee River Basin. Maybe you already know all this, but if you don’t, these pictures may help make sense of Springsheds and Water Withdrawal Permits in the Suwannee River Basin.

Springsheds and Water Withdrawal Permits in the Suwannee River Basin

This figure for Florida water withdrawal permits in the Suwannee River springsheds shows by far the largest blue dots for the biggest withdrawal permits in Hamilton County at the location of the PCS Phosphate mine.

What is Sabal Trail up to at Pilgrim’s Pride and Suwannee River? 2017-03-20

Following up on Cody Suggs’ pictures of pipeline dug up at Pilgrim’s Pride, I found a flock of glow-shirts inspecting a fancy new pipeline sign. Remember, where Sabal Trail goes through Pilgrim’s Pride property is right next to at least two large sinkholes and on top of the world-famous miles-long Falmouth Cathedral Cave System that feeds the Floridan Aquifer from which we all drink. They were also across US 90 and the railroad, and then at the Suwannee River HDD site in Suwannee County, Florida. Here are many pictures, a video playlist, and a Google Map.

Videos: Coal Ash meeting in Valdosta @ WWALS 2017-03-01

The Georgia legislature did nothing but appoint a study committee, but you can see why they should do more, in these WWALS videos of the coal ash meeting in Valdosta that was organized by Rev. Deacon Leeann Culbreath of Georgia Interfaith Power & Light (GIPL). Thanks to Rev. Floyd Rose for the venue at Academy of Excellence on Lee Street.

The Valdosta Daily Times covered this meeting, but did not mention the local landfill, which was a major topic of my presentation, as you can see in my slides. The Mayor of Valdosta disclaims any control over that landfill and the Lowndes County Commission expressed no interest. Nevermind both city and county governments have Continue reading
