Water withdrawals from the Floridan Aquifer affect water levels and quality in the Okefenokee Swamp,
a pair of researchers concluded 24 years before Twin Pines Minerals of Alabama proposed to withdraw
2.4 4.32 million gallons per day from the Aquifer for a titanium mine within a few miles of the Swamp:
Abstract. A rapid response is observed between water level fluctuations in the Okefenokee Swamp and water levels in the underlying Floridan Aquifer. A lag of approximately one month is common, and a hydraulic diffusivity of 3.83 x 10-3 m2 s-1 best matches the calculated aquifer response to the swamp water level perturbations. The magnitude of leakage between the swamp and the aquifer is uncertain because of a lack of knowledge about the specific storage coefficient in the aquitard separating the swamp and the aquifer which has not been explicitly measured. An intermediate value of specific storage within the likely range of values results in a down- ward vertical flow of 1.2 meters of water per year. This induced recharge can significantly alter the natural water balance within the swamp. Such a large loss of water from the swamp may be responsible for observed pH and water level changes, and increased beavy metal accumulations in aquatic organisms in the swamp.
We cited that study on page 4 of the Suwannee Riverkeeper comments to USACE about TPM, just after noting Twin Pines application to withdraw 4.32 million gallons per day (mgd) of Floridan Aquifer water much closer to the Swamp than any other permitted withdrawal. TPM’s own hydrology study in that withdrawal application shows a cone of depression in the Floridan Aquifer extending under the Swamp:
How could that not affect Swamp water levels and content?
As pointed out to the Corps by Okefenokee Swamp Park (OSP), any change to the water level in the Swamp would affect the whole Swamp, as far as OSP on the north and Stephen C. Foster State Park on the west. The Swamp is the headwaters of the Suwannee and St. Mary’s Rivers, so anything that affects the Swamp can affect those rivers.
As we noted in a later blog post, 4.32 mgd is twice as much as all the permitted withdrawals in Charlton County, 4.32 times as much as the county seat, Folkston, and almost four times as much as the notorious Nestlé withdrawal request for Ginnie Springs on the Santa Fe River in Florida.
You can still comment to the U.S. Army Corps of Engineers about the TPM mining application. Or to GA-EPD about this water withdrawal permit.
Help Suwannee Riverkeeper save the Okefenokee Swamp
You can object to a titanium strip mine proposed far too near the Swamp.
You can write to your Georgia state representative or senator or governor or lieutenant governor and ask them to refuse any such instrument.

These are the Georgia state Senators with districts most involved with the Okefenokee Swamp:
- District 003 Senator Sheila McNeil (R-Brunswick) (Brantley County), (404) 656-9644, 912.464.1989, firstname.lastname@example.org, email@example.com With the new redistricting, District 3 will include all of Charlton County, including the mine site.
- District 008, Senator Russ Goodman (R-Lake Park) (Lowndes, Lanier, Echols, Clinch, Cook, Brooks, and Thomas Counties), (404) 656-7454, 912-218-0447, firstname.lastname@example.org, email@example.com With the new redistricting, Senate District 8 no longer will include any of Charlton County, so not the mine site, but it will include the south and west parts of Ware County, so the Okefenokee Swamp west of the mine site.
- District 007 Senator Tyler Harper (R-Ocilla) (Tift, Berrien, Irwin, Ben Hill, Coffee, Bacon, Atkinson, Ware, and Charlton Counties), (404) 463-5263, firstname.lastname@example.org. His district includes the Okefenokee Swamp, and he is the Chair of the Senate Natural Resources and Environment Committee. With the new redistricting, Senate District 7 goes away entirely, being absorbed by District 8 and District 3.
These are the Georgia state Representatives with districts most involved:
- 174, John Corbett, R - Lake Park, 404-656-0213, email@example.com. District 174 district includes the mine site. With the new redistricting, it will also include the rest of Charlton County.
- 180, Steven Sainz, R - Woodbine, 404.656.0177, firstname.lastname@example.org, Charlton and Ware Counties. With the new redistricting, District 180 will not include any of Charlton County; only Camden County and a bit of Glynn County.
- 176, James Burchett, R - Waycross, 404.656.0188, email@example.com, Lowndes, Lanier, Atkinson, and Ware Counties. With the new redistricting, also a bit of Coffee County.
- 177, Dexter Sharper, D - Valdosta, 404.656.0126, firstname.lastname@example.org, Lowndes County. Valdosta is the most populous city in the Suwannee River Basin in Georgia or Florida.
You can also write to your U.S. Representative or Senator and ask them to urge the Corps to take back up its oversight of the mine site. See former letter from Rep. Al Lawson (FL-05).
