Proposed EPA Water rule

The U.S. Environmental Protection Agency proposes some new rules to clarify Clean Water Act protection. Some people and organizations have concerns about that, and the EPA has now responded to those concerns. Comment periods are still open for you to provide input directly to EPA about the proposed rule.

Here’s the EPA’s Waters of the United States Proposed Rule. EPA says clarification of the Clean Water Act was requested by a broad range of state, tribal, and local government agencies and elected officials and NGOs, ranging from AASHTO to the National Association of State Foresters. One of the two examples EPA cites of state enforcement problems is on the Flint River in Georgia:

Suwannee Bioregion Coalition?

Related to population centers in the Suwannee River watershed, someone asked, “Do we need an interstate Suwannee Bioregion Coalition to guard the waters that feed into the Suwannee River?” We’ve got pieces of it already cooperating to some extent in opposing the Sabal Trail pipeline. There are many other even larger issues that everyone in the Suwannee River basin faces.

In south Georgia and north Florida we have Continue reading →

Avoid our area –Florida’s Suwannee River Water Management District to FERC

What they told FERC today was more subtle than just “avoid our area”, but after the Sabal Trail methane pipeline avoid karst limestone, any unconfined areas of our Floridan aquifer, caves, springs, wetlands, drilling under rivers, blasting, or using groundwater for testing pipes or disposing of it afterwards, where can that pipeline go?

The Suwannee River Water Management District (SRWMD) covers the Florida parts of WWALS’ watersheds, and our Withlacoochee River is named in the SRWMD comments. Unlike Georgia’s Suwannee-Satilla Water management District, SRWMD has state funding and staff that produced some very interesting comments.

This is the first I’ve heard of this point about source and disposal of testing water: Continue reading →

Entering the Floridan Aquifer Recharge zone –Kristofer Graham

Written as a newspaper letter to the editor and posted here with permission. -jsq

Dear Residents
Did you know Lanier County doesn’t have zoning laws. Which that mean they can development on wetlands and on our Floridan Aquifer Recharge zone and build resident houses, subdivided, commercial building etc., cut timber on wetlands, on our watersheds and a Natural Gas Company want to put a pipeline through on these precious lands they can. It will destroy the land environment like our Floridan Aquifer Recharge zone (aka our drinking water) and our wetlands and our watersheds. Because it not protected like it should.
Well it time to protect it before it all destroy and gone. It is up to our local government to protect these precious lands and preserve it in the original state. Yes it’s time for our local government to do there job to protect it. So it can be there forever.
I notices they got those lands zone as Ag and V5 zone. Which those zone doesn’t protect it and in fact it can destroy those lands Eco system because they spray pesticide for there farm crops near the Floridan Aquifer Recharge zone and wetlands, our watersheds. It will Continue reading →

Aquifer storage meeting in Newton, GA 7 November 2013

It looks like SB 213 is being resurrected after falling in the Georgia House in March. This GEFA ASR meeting is in Newton, which is not far west of Tifton. When will they be coming for the waters of the Little River, too?

Jim West in the Albany Herald 29 March 2013, Flint River bill fails in the House, quoted Gordon Rogers, Flint Riverkeeper, and then referred to Georgia Water Coalition:

One aspect of the bill river advocates found objectionable was the concept of “stream flow augmentation,” including aquifer storage and recovery, or ASR, which Coalition officials define as “the injection of ground water into the aquifer, which would be extracted later and sent downstream.” According to the Coalition, the process could cause irreversible contamination of the aquifer.

Videos: Aquifers, sinkholes, and groundscans –Prof. Don Thieme

We had to move to a larger room, so many attended this groundwater talk at VSU (about 90). Plus a guest appearance by SAVE.

Here are Dr. Donald M. Thieme‘s slides in PDF, with his longer title:

Coastal Plain Surficial Deposits, Groundwater Resources, and Recent Subsidence in south Georgia

While we are lucky to have abundant groundwater, both from the Upper Floridan Aquifer 100 feet below us trapped in Eocene limestones and from shallow groundwater with its karst features, nonetheless overpumping has caused falls in the level of the aquifer (about 0.6 feet a year at Valdosta), resulting in rapid loss of shallow groundwater, plus surface water that enters and often contaminates the aquifer through those karst features.

Sometimes those karst features subside and manifest as sinkholes like the one that ate Snake Nation Road in Lowndes County and others that can develop slow (many years) or fast (weeks or minutes).

There were also many questions, starting with what water do personal wells reach? Also including a brief history of Valdosta well drilling from artesian to hundreds of feet down, and a sinkhole in a garage in Lowndes County, should local governments require sinkhole insurance (including mention of Moody AFB subsidence and Florida citrus growers pumping so much water it causes sinkholes). I also introduced the WWALS board members present: Gretchen Quarterman (Treasurer and videoing), Bret Wagenhorst (Outings), Heather Brasell (Secretary), Dave Hetzel (President), April Huntley (Director), me (Vice President), and Chris Graham (Member); plus a brief summary of WWALS events and outings. Here’s a video playlist:

Aquifer at max pumping in central Florida

Remember, this is our aquifer, too. And watch out! They’d rather pipe somebody else’s river water than conserve in Central Florida.

Kevin Spear wrote for the Orlando Sentinel yesterday, Analysis: Floridan Aquifer can only handle 6% more pumping before serious environmental harm,

Just how much more water can Central Florida pump from the Floridan Aquifer without causing real harm to the region’s environment? After years of debate, study and anxiety, state authorities say they have finally — and officially — figured it out.

The answer: hardly any.

Using the most advanced databases and computing methodology yet developed for such a task, a consortium of state water managers and local utilities have calculated that the current amount of water pumped from the underground aquifer each day can be increased by only about 6 percent — which means the region is already exploiting the huge, life-sustaining aquifer for nearly every drop it can safely offer.

Beware! 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.

Entering Floridan Aquifer Recharge Zone

Maybe we need signs like that around here to remind people that what goes into the ground comes out in our drinking water. For example, San Antonio has its Edwards Aquifer Protection Program. Maybe our local governments need to have Floridan Aquifer Protection Programs. Georgia state law seems to indicate they should.

GA Secretary of State has GA Code §391-3-16-.02 Criteria For Protection of Groundwater Recharge Areas. (more legible copy on GA EPD website),

(1) Background. Variable levels of recharge area protection can be based upon the State’s hydrogeology (e.g., areas such as the Dougherty Plain where a major aquifer crops out would receive a relatively high degree of protection whereas other areas, such as the shale hills of northwest Georgia, would receive a lower degree of protection). Recharge area protection within the significant recharge areas would be further refined, based upon the local susceptibility or vulnerability to human induced pollution (e.g., high, medium, or low). The significant recharge areas have already been identified and mapped (about 22-23% of the State). Pollution susceptibility mapping is ongoing. Existing statutes are adequate for protecting the remaining recharge areas (about 77-78% of the State).

(2)(f)3. In the Coastal Plain, the significant recharge areas are Continue reading →

Oil drilling in our aquifer?

There’s a bill in the Florida House to drill for oil in a state park in the same aquifer we drink out of.

A group is organizing through facebook and reddit and elsewhere to oppose this bill:

Save Blackwater River State Forest
An alliance of citizens committed to protecting the beautiful Blackwater River State Forest from proposed House Bill 431, that would allow oil and mining in the forest.
