Hotter temperatures are making the ground drier and causing water to evaporate more quickly, resulting in less groundwater and less surface water flowing into lakes and rivers like the Colorado River, which provides water to seven states, including Arizona. Fulton Schools Assistant Professor Margaret Garcia, who studies factors influencing the sustainability and resilience of urban water supply systems, says it’s time for serious decisions to be made on using less and conserving more of the region’s water. Garcia and other experts call for government, industry, business and community leaders to work together on strategies to provide adequate water resources while also preventing widespread depletion of water resources.
