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^[5] 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.
