A team of Fulton Schools civil and environmental engineering students took on a challenge to purify wastewater to make it safe for human consumption. The project — conducted at a water treatment plant in the town of Fountain Hills, near Scottsdale — was part of the American Society of Civil Engineers Pacific Southwest Conference annual student competitions, which were held this year at Arizona State University. The water treatment competition required students to sufficiently remove contaminants so that the water met drinking standards.
