Doug Bartlett, RG, CHG, of Clear Creek Associates and an affiliate team member 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.”
Topics covered in the publication include:
Groundwater Fundamentals and Occurrence
Managed Aquifer Recharge Concepts
Design and Testing
Operations and Maintenance of MAR Facilities
Data Collection and Analysis
Clear Creek and DBS&A, who are affiliate companies through their ownership by Geo-Logic Associates, are regional experts and pioneers in MAR project implementation. Click here to learn more about Clear Creek’s MAR expertise. MAR expertise we offer includes:

Several case studies in the ASCE/EWRI publication feature DBS&A and Clear Creek projects, including:
City of Phoenix ASR Well 299 operated by the City of Phoenix, Arizona. Learn more about the City’s sustainability initiatives.
Rio Rancho Direct Injection Demonstration, operated by the City of Rio Rancho. Learn about the City of Rio Rancho’s aquifer injection project.
In a letter of recommendation, Andrew Haas, PE, Vice President of Engineering of AWC recognized that “the Company’s use of CAP water through recharge, storage, and recovery complies with and advances a crucial Arizona public policy by efficiently and cost-effectively using the state’s Colorado River water supply, reducing the reliance on mined native groundwater.”
