Cowboy ButchSixth Grader Rahul Sayal, a student at Young Scholar’s Academy in Fort Mohave, makes a presentation to the Mohave County Board of Supervisors March 21, 2016. The young scholar explained how the Colorado River water can be purified into drinking water. He told the supervisors that solar energy is an effective method of water purification as compared to SODIS and this could solve the problem of availability of drinking water in the Colorado River Basin. SODIS is a method of using clear plastic bottles filled with the water and set out in the sun for six hours. The UV-A rays in sunlight kill germs such as viruses, bacteria and parasites (Giardia and Cryptosporidium) and also works when air and water temperatures are low.
