Tallahassee, we have a problem...


We have a water problem. No, it's not just Atlanta. No, it's not just South Florida. Jacksonville have a water problem, too. St. Johns Riverkeeper says it so much better than I do, so I'll use their words. Here's the overview:

  • According to the St. Johns River Water Management District (SJRWMD), Central Florida has out-stripped the Floridan Aquifer's ability to provide a sustainable drinking water source beyond 2013. The District has told communities they will have to seek alternative water supply (AWS) sources, such as surface water and desalinization.
  • The SJRWMD has stated that 155 million gallons of water per day (MGD) can be removed from the St. Johns River between the headwaters and Deland to provide water for Orlando and Central Florida without harming the health of the river.
  • Because river water has a high salt or mineral content, most withdrawls will require treatment by reverse osmosis, or RO. A by-product of RO is high mineral content and/or very salty water. RO water is also high in nutrients. The by-products, or pollutants, are called "concentrate". The SJRWMD recently began a study to determine the impacts of the concentrate on the river environment. The study will end in a year.
  • The SJRWMD is also focusing its attention on the lower Ocklawaha River. Although District staff has not set a minimum flow level, of MFL, for the Ocklawaha River, the agency is telling counties to expect to be able to withdraw 90-108 MGD from the Ocklawaha.
  • The withdrawls from the St. Johns and Ocklawaha could total 263 million gallons per day.
  • Withdrawls from the St. Johns will impact the river's salinity line.
  • One of the largest proposed water withdrawls, Yankee Lake, is planned in an area just south of the Wekiva Aquatic Preserve. Also, this plant could eventually discharge RO concentrate into the river.
  • The only county proposing to withdraw water from the River that has a mandatory water conservation plan is Volusia County. None of the other counties or municipalities that are planning water withdrawls has mandatory water conservation programs.
  • The proposed withdrawls will cost of $1 Billion. These plans will only provide drinking water needs until around 2030, less than 25 years into the future.
St. Johns Riverkeeper Concerns:

  • Riverkeeper is concerned that the withdrawls from the St. Johns and Ocklawaha could potentially cause significant harm to the health of both rivers.
  • The withdrawls will cause the St. Johns River's salinity line to shift upstream, especially during drought and low flow conditions. No one, including the SJRWMD, fully understands all of the potential impacts of the river's health and fisheries from the proposed withdrawls.
  • In addition to withdrawing water from the St. Johns and Ocklawaha, the SJRWMD is also proposing to utilize Aquifer Storage Recovery, or ASR. ASR is a process that injects minimally treated water back into ground water aquifers for storage until it is needed at a later date. There are significant risks associated with this procedure.
  • "Concentrate" from RO processes could hard the St. Johns River's health by adding additional pollutants to an already stressed system. Riverkeeper is concerned the SJRWMD could issue numerous withdrawl permits before the RO concentrate study is completed.
  • The SJRWMD has not required mandatory conservation programs in an attempt to reduce the need to withdraw river water, despite the fact that residents within the watershed of the St. Johns use approximately 150 gallons of water per person each and every day.
  • All of the District's studies rationalizing and/or minimizing the environmental impacts of water withdrawls have been done 'in house', i.e. written by staff or consultants paid for by the District. There has been no independent review of any of these reports.
  • Once the river water withdrawl process begins, it will be extremely difficult to reverse course, even if the act results in harm to the river's ecological health.
  • Riverkeeper is concerned that this may only be the beginning of water withdrawls from the St. Johns and its tributaries. As groundwater supplies continue to be depleted, there will be more pressure to continue this process and allow additional withdrawls in the future.
  • The SJRWMD has poorly managed our groundwater supplies and how wants to manage the withdrawl of water from our rivers. The District should turn its attention to water conservation, desalinization, and more sustainable planning practices before ever considering the St. Johns and Ocklawaha as an alternative supply sources.
  • The St. Johns River is one of the "laziest" rivers in the world, dropping less than 30 feet from its source at its mouth. This fact combined with tidal influences makes it difficult for our river to efficiently flush pollutants and sediments. Removing the amount of water that is being proposed will potentially worsen pollution problems.
What can you do:

Let Governor Crist, the SJRWMD Governing Board, and your local elected officials know that you oppose the proposal to withdraw water from the St. Johns River and Ocklawaha River. Tell them to require and support water conservation and desalinization efforts first.
Visit St. Johns Riverkeeper's webpage to find email addresses and form letter to send to your elected officials.

Take a moment this weekend to visit YOUR river. Go to the Landing... go to Cummer... Go to the Riverwalk... Take a Water Taxi ride. Experience the River and you will want to protect it.

Hi!

We are glad that Sustainabuild is bringing our River's issues to the forefront. We have also started a blog, as part of our Homeschooling projects, to track down and find out where all the pollution is coming from in Jacksonville. Send us your tips! We will document and post on our blog - www.stjohnsriverblog.blogspot.com - Let's all work together to save the St. Johns!
