Current Work & Goals
Water reuse represents a major opportunity to supplement existing water supplies. Many potential water sources such as industrial process water, agricultural return flows, municipal wastewater, oil and gas produced water, and stormwater can be captured and used for enhanced aquifer recharge.
Established in September 2019, the Aquifer Storage and Recovery – Managed Aquifer Recharge (ASR-MAR) Workgroup was formed to examine, discuss, and make recommendations to the GWPC Board of Directors regarding Aquifer Storage and Recovery (ASR) and Managed Aquifer Recharge (MAR) issues or topics.
The Workgroup serves as a forum for Federal, State, Tribal, and local government, organizations and public interest, and professional organizations to exchange information, views, and ideas, and to communicate and collaborate on efforts concerning ASR and MAR issues or topics. Its efforts are not limited in scope to just UIC issues. The issues that may be examined are broad and may include enhanced or managed aquifer recharge practices that are not regulated by the SDWA UIC program.

The GWPC ASR-MAR Workgroup has been identified in the U.S. EPA National Water Reuse Action Plan (Action 7.4) as a leader to increase understanding of current aquifer storage and recovery practices. The action item recognizes that there are differences in how aquifer recharge is described, implemented and managed. The action seeks to better understand the range of aquifer storage and recovery practices and corresponding efforts to ensure the protection and sustainability of groundwater resources. The GWPC Workgroup will facilitate meetings to study and find solutions to the challenges currently limiting the use of Enhanced Aquifer Recharge (EAR) and ASR-MAR.
A project of the GWPC ASR-MAR Work Group, the ASR-MAR Library is an easily searchable collection of materials related to ASR-MAR. As the collection grows, it is our hope that this resource will be useful to regulators, water managers, and practitioners. The library will aim to facilitate increased understanding of current ASR issues and practices.
