On the Road to Achievement: Safe Yield in Central Arizona

摘要

FOR A DIFFERENT PERSPECTIVE ON WATER SUPPLY management, the state of Arizona continues to make strides toward ensuring long-term water sustainability. Earlier this year, Arizona celebrated the 40-year anniversary of its Groundwater Management Act of 1980. The Act is lauded for positioning Arizona as one of the first states to create a manageable system for governing its groundwater use.
