While out digging around on the internet I ran across this article.
If you’ve ever been to an island, water is probably one of the biggest problems they can have… Especially Clean Water. It’s a problem in the states as well. Many times in the Caribbean it comes down to two ideas for water – desalinization or cisterns. Desalinization isn’t cheap – and it can be a slow process – that’s what makes this article noteworthy.
Not to re-explain the entire article, scientists have been looking at electodialysis for desalinization. except that doesn’t clean all the bad parts out.
“Now Deng and co say they have found a way to produce clean drinking water in a single step using electrodialysis. The key is to place a layer of porous material close to the cathode which then acts as a filter and removes anything that cannot pass through the micropores.
The porous material in question is fitted glass, which is made by sintering together glass particles to form a porous solid. The pore size is around 0.5 micrometres so anything larger than that, such as dirt particles, cannot pass.”
Here’s hoping they get it down in cost and size. It does require electricity – so maybe there can be a whole solar component to this.
Clean Water Camp 2014 Video
/in Clean Water, Conservation, TenneSEA/by Mary Beth SuttonWe just don’t work in the Caribbean – Clean Water is a bit of a problem everywhere. Check out this video for the work done on South Chickamauga Creek.
The Clean water camp is one of the things we do locally in Tennessee/Georgia.

Giving Tuesday
/in Clean Water, Conservation, HELP!, TenneSEA/by Mary Beth SuttonToday is Giving Tuesday. Please consider the Caribbean SEA and TenneSEA Kids 4 Clean Water in your charitable giving plans.
During the busy holiday season, please consider helping Caribbean and TenneSEA provide programs for Students and Communities to better protect and restore our precious water. From rain gardens at schools in Tennessee to constructed wetlands and latrines in under developed countries, our kids are leading the way to better water (and learning Science and Engineering at the same time)!
There are 3 ways you can help!

/in Uncategorized/by Mary Beth SuttonIt’s been a crazy winter, so I KNOW you are ready for the FIRST DAY OF SPRING!! So are we, so we are celebrating the First Day of Spring at the Flying Squirrel in Chattanooga (http://flyingsquirrelbar.com/) and they are donating a portion of the proceeds to our Kids 4 Clean Water programs! So come join us Thursday!
What’s happening to the Bay in St Lucia?
/in Clean Water, Coral, snorkeling, st lucia/by Mary Beth SuttonAs most ecologists know, observing the same location over time tells you a story about what is going on with the health of the ecosystem. We have a small ecosystem in trouble….a favorite little bay in St. Lucia where Katie (and Nina and Sam, Kievan, Karim, and Selena and sometimes even Keiwa) likes to jump off of the high rocks. The reef was so beautiful when I first saw it many years ago. It still has a diverse array of coral species, but at least half of the bay now has mostly dead coral. The fish population was equally diverse, but now very few fish call the bay home. And what happened to all the sea urchins? They are such important grazers of the reef and none were there this week. It is likely that the Christmas Eve storm that devastated St. Lucia dislodged and killed the sea urchins. The sediment from the torrential rains from Hurricane Tomas in 2010 and again on Christmas Eve have seriously damaged the corals. Green algae is growing more abundantly, likely aided by nutrient enrichment. We have been challenged to try to reverse this process. Even as we can see that the corals of the outer bay seem to be healthier than just after Tomas, others are bleached and dying
