Long-term storage credits, Arizona's Innovative Water Banking System

Within Arizona's Active Management Areas (areas in which groundwater use is highly regulated) there is a cap and trade system for groundwater, and cities, Tribes and other entities can accrue and exchange long term storage credits for water that is stored in underground aquifers. This report explains how these credits are accrued and accounted for and how they have become an integral tool for water providers. It includes a dashboard of long term storage credit accounts in Arizona.
