Stephanie Moore, PG, Senior Hydrologist at DBS&A and affiliate team member Doug Bartlett, RG, CHG, of Clear Creek Associates, are contributing authors of the American Society of Civil Engineers’ Environmental and Water Resources Institute (ASCE/EWRI) recent publication, Standard Guidelines for Managed Aquifer Recharge [MAR] (69-19). MAR refers to the recharge of aquifers using infiltration basins, vadose zone wells, injection wells, and other methods, including aquifer storage and recovery (ASR) wells. MAR has become a widely used tool for the management of sustainable water supplies, particularly in the desert Southwest.
In 2005, the ASCE/EWRI formed the Guideline Development Subcommittee for MAR to “…provide a thorough and up-to-date document that describes the state of the practice for MAR projects.” The Guidelines were “…designed to meet the needs of water resources planners and stakeholders during the initial evaluation and planning phases, and the needs of engineers, hydrologists, and other professionals for standardization of MAR practices from conceptualization to operation.”
According to Ms. Moore, “From our work with MAR projects around the Southwest, Doug and I understood the value of MAR as a conjunctive management tool that provides increased resiliency to water resources managers. However, the existing guidelines were outdated. We worked with our fellow contributing authors to provide an up-to-date, comprehensive document to facilitate the implementation of successful MAR projects in the U.S.” Topics covered in the publication include:
- Groundwater Fundamentals and Occurrence
- Managed Aquifer Recharge Concepts
- Design and Testing
- Operations and Maintenance of MAR Facilities
- Facility Closure
- Data Collection and Analysis
