Here is a question about this article: The Arena Football League (AFL) is the highest level of professional indoor American football in the United States.

Here is a question about this article: In an effort to conserve water, Tucson is recharging groundwater supplies by running part of its share of CAP water into various open portions of local rivers to seep into their aquifer. Additional study is scheduled to determine the amount of water that is lost through evaporation from the open areas, especially during the summer. The City of Tucson already provides reclaimed water to its inhabitants, but it is only used for "applications such as irrigation, dust control, and industrial uses." These resources have been in place for more than 27 years, and deliver to over 900 locations.
What is the answer to this question: How is Tucson replenishing its groundwater?
