One of the challenges facing the community of Borrego Springs is how to use our aquifer in a sustainable manner.  Borrego Springs has a serious overdraft situation; the farmers, golf courses, and residents in the Borrego Valley pump out approximately 20,000 acre feet of water each year but only 5,600 acre feet of new water sinks in to replace it. The Borrego Water District and the Borrego Water Coalition are working to come up with a solution, a way to make our use of water sustainable, and it's a complex problem.  The goal of ABDNHA's Water Wizards Program was to bring this issue to the children of Borrego Springs, to a group of 21 students selected by the school, in a special hands-on afterschool science program, so they could understand how aquifers work, where our water comes from, the system of pumps and pipes that bring water to our homes, and the real-life water problem that our community needs to solve.   Students make an aquifer in a glass, complete with permeable layers and non-permeable layers, using rocks, clay, and sand.  They then filled it with water to see how the different layers function. Students work with a scale model of the Borrego Valley water system, from the aquifer (fish tank on the right) pumping up to a storage tank (plastic bottle) and then distributed by gravity out to their households, with faucets to represent houses.
