“Team Charger 4” was awarded by judges for its efforts to create an inexpensive and easily accessible way to improve unsanitary water conditions in underdeveloped countries. The team concocted a solution of unsanitary water to test a new and advanced water purification system using the process of reverse osmosis. The device, which was created using a coffee filter and dialysis tubing, was tested for titration on water and was then measured by recording the acidity and turbidity levels in the water sample. The team’s results showed that its purification system filtered out large particles, reduced turbidity levels and increased the pH level to a value closer to pure water. They hope to further their experimentation by testing whether bacteria are present before and after filtration through culturing an organism’s presence on nutrient agar.

Each student on "Team Charger 4" has won $3,000.00 in U.S. EE Savings Bonds, a certificate of recognition from the U.S. Army, and an expenses-paid trip to the National Judging and Educational Event in Washington D.C. in June to present their final projects and compete for an additional $5,000.00 in U.S. EE Savings Bonds.
