May 31, 2017 (Source: FIU) - Florida leads the south in water efficiency, according to a study examining water use across the United States. While states in the north have become more water efficient, their southern counterparts have not. Florida is the exception with water use in homes, business and public spaces declining over the past 30 years in the Sunshine State. Broward and Palm Beach were the most efficient counties, while Hardee and DeSoto were the least efficient. These findings are consistent with the national findings that show increased water efficiency in urban areas while rural areas have become less efficient. "Florida is the third most populous state in the country and it is largely urban, which accounts for its higher water efficiency compared to other southern states," said FIU biologist John Kominoski, a co-author of the study.
