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).

Impacts of Variable Climate and Effluent Flows on the Transboundary Santa Cruz Aquifer
ABSTRACT: Assessing groundwater resources in the arid and semiarid borderlands of the United States and Mexico represents a challenge for land and water managers, particularly in the Transboundary Santa Cruz Aquifer (TSCA). Population growth, residential construction, and industrial activities have increased groundwater demand in the TSCA, in addition to wastewater treatment and sanitation demands. These activities, coupled with climate variability, influence the hydrology of the TSCA and emphasize the need for groundwater assessment tools for decision-making purposes. This study assesses the...

An Overview of Managed Aquifer Recharge in Mexico and Its Legal Framework
In Mexico, one hundred of the 188 most important aquifers dedicated to agriculture and human consumption are over-exploited and 32 are a ected by seawater intrusion in coastal areas. Considering that Mexico relies on groundwater, it is vital to develop a portfolio of alternatives to recover aquifers and examine policies and programs regarding reclaimed water and stormwater. Managed Aquifer Recharge (MAR) may be useful for increasing water availability and adapting to climate change in semi-arid regions of Mexico. In this paper, we present an overview of water recharge projects that have been...

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...

Layperson's Guide to Arizona Water
As part of its commitment to serve the water education needs of Arizona citizens, the Water Resources Research Center teamed up with the Water Education Foundation to produce the Layperson’s Guide to Arizona Water. The publication meets a longstanding need: it offers in a single, reader-friendly source information Arizona citizens need to be well informed about state water issues. Few would doubt the need for a layperson’s guide or primer describing the ins and outs of Arizona water. Arizona is a rapidly growing state attracting people from many different areas who need to be...

Rain Barrel Water Harvesting Guide
The southwestern United States and northwestern Mexico have generally dry climates and rapidly growing populations. Both Nogales, Arizona, and Nogales, Sonora, have limited water resources and must rely on the drought-prone Santa Cruz River for 50 percent or more of their water supply. A 6-page "how-to" guide on the basic principles of rain barrel water harvesting and information about installing your own system. This guide was prepared for the Nogales Rainwater Harvesting Open House.
