Looming Water Gap in the Colorado River Basin Leads Two Arizona Communities toward Integrated Land and Water Planning
Arguably, managing water separately from land was one of the great missteps of the 20th century. Turning our eyes to past practices, and recognizing the role watersheds play in the health of the environment and our communities, we see that land and water must be managed together as integrated social-natural systems. This issue of Water Resources IMPACT is a companion to the AWRA 2021 Virtual Summer Conference: Connecting Land & Water for Healthy Communities, convening in July 2021. As co-chair of the AWRA Integrated Water Resources Management Technical Committee, and in partnership with...

Preparing Rainwater for Potable Use
Rainwater harvesting can provide a realistic source of water for homeowners living in remote areas or those who for one reason or another prefer not to use their groundwater inside the house. Local groundwater may have problems common in many parts of Arizona: high mineral content, naturally occurring elements such as arsenic and fluoride, and contaminants from various sources, such as overflowing septic tanks, and agricultural, industrial or mining activities. Homeowners may have low-yield or seasonally dry wells and wish to avoid trucking in water. They may be unwilling or unable to drill...

The U.S.-Mexico Transboundary Aquifer Assessment Program as a Model for Transborder Groundwater Collaboration
The assessment of transboundary aquifers is essential for the development of groundwater management strategies and the sustainable use of groundwater resources. The Transboundary Aquifer Assessment Program (TAAP) is a joint effort by the United States and Mexico to evaluate shared aquifers. This study examines the TAAP Cooperative Framework as a guide for further transboundary groundwater collaboration. We compared lessons learned from six transboundary aquifers that currently have mechanisms for groundwater collaboration to identify common elements of collaboration. Though the TAAP...

Rain Water Harvesting Saves Water and Supports Healthy Trees
Water conservation is an important issue in the Southwest. Many urban landscapes use native or desert-adapted plants to reduce the amount of irrigation needed. Harvesting rainwater is another strategy to supplement irrigation and reduce potable water use. Rainwater harvesting has become more popular in recent years for both commercial and private properties to conserve water. Other benefits include reducing stormwater runoff, flooding, and soil erosion, and getting free, good quality water for irrigating plants.

2020 WOTUS Rule
The United States has had a tumultuous relationship with one of its most precious resources — water. By the 1970s, aggressive development in the United States necessitated the implementation of regulatory measures to protect the environment. Since then, the debate has focused not on whether the environment should be protected, but how comprehensively that regulatory protection should extend. Nowhere has this debate been more evident than with the federal Clean Water Act (CWA) and the definition of “waters of the United States” (WOTUS).

Well Owners' Guide to Ground Water Resources in Yavapai County
An individual in an industrialized urban society may use from one million to five million gallons of water during their lifetime. If the share of industrial, agricultural, and recreational usage is counted, the total amount of water may exceed ten million gallons per capita. Water resources are those sources of water that meet the need of the individual and society, and the value of that resource depends on demand and availability. Our arid climate, coupled with increasing demands on water supply and the over—allocation of surface water resources, forces much of Yavapai County to rely on...
