GRAND
CHALLENGE
THE GEORGE BARLEY WATER PRIZE
The final ‘Grand Challenge’ stage of the George Barley Water Prize will be the robust testing of contestants under field conditions in the Greater Everglades to validate whether these leading technologies can remove phosphorus from the Kissimmee River or a comparable water body under real conditions at significantly lower cost than currently possible.
The 9 Pilot Phase teams will be narrowed down to the final four, who will move on to the final stage of the competition. Advancers will be announced in October 2018, in Toronto, during Canada’s Water Innovation Week. While Stage 3 asked teams to perform through snowmelt conditions, Stage 4 will require teams to demonstrate their ability to perform in subtropical conditions. Four teams will receive continuous flow, averaging 1 million gallons per day (gpd), with a variable spike of 4 million gallons per day, over the course of 14 months.
A Grand Challenge winner will have demonstrated endurance in a range temperatures, proving their technology is globally applicable. With the support of the State of Florida’s Department of Environmental Protection and the St. John’s River Water Management District, the Grand Challenge will be hosted on the banks of Lake Jesup, in Oviedo, Florida.
In this stage the prize purse is a
$10 Million Grand Prize
$250,000 Secondary Prize
$170,000 Phoenix Prize
competitors are judged on
1. TP results from grand stage testing
2. Cost calculations
3. Background water characteristics
4. Waste disposal plan
5. Environmental outcome assessment
6. By-product recovery income plan
7. Twenty-page scalability plan

MAC STONE
BOARD MEMBER
Mac Stone is a conservation photographer from Gainesville, Florida. Growing up exploring the springs, swamps, and hammocks of North Central Florida, he developed a passion for photography at a young age. Over the years his camera has carried him to some of the most remote and imperiled areas this side of the globe. For six months, Stone lived in Ecuador during the presidential overthrow of 2005 and worked with Wildlife Conservation Society biologists in the Amazon rainforest. Soon after, he moved to Honduras and lived in a small village along the Cangrejal River. For two years he taught photography to underprivileged youth as a way to raise environmental awareness in the region. Some of the students have gone on to win international acclaim and start up their own eco-tourism businesses. Through photography, Stone strives to start new conversations and expose the dynamic relationship between mankind and the natural world. Currently, his work focuses on America’s swamps in an attempt to change public opinion towards our country’s wetlands. After spending five years living and working in the Everglades watershed, he released a 304-page coffee table book about the heralded River of Grass. Everglades: America’s Wetland, published by University Press of Florida in October of 2014 has won a silver medal with the Florida Book Awards and is now in its second printing. In March of 2015 he delivered his first TED talk about this body of work. When he is not photographing the bottomlands and backwoods of the southeastern US, Stone is a product tester for Columbia Sportswear, a Google Trekker, winner of the Save Our Seas Foundation Marine Conservation Photography Grant, official photographer for Savage Race, a fellow of the International League of Conservation Photographers and the Executive Director of Naturaland Trust.
