Callen Solley from Rocky Mountain High School addressed water use and polluted runoff by providing a soil moisture sensor to a golf course. Over 2 billion gallons of water are dumped onto golf courses in the United States each year. In addition to that, most of them are overwatered which creates excess runoff that carries fertilizers into the watershed creating algae blooms. A great way to stop the issue of overwatering is utilizing a soil moisture sensor. The sensor measures how much water is in the soil. These readings can help a golf course adjust the amount of water they are putting on the grass. This solution addressed targets 6.3 and 14.1 of the Sustainable Development Goals.
