Geochemical Considerations for Managed Aquifer Recharge Implementation in Potable Reuse
Managed Aquifer Recharge (MAR) is the intentional recharge of water into a subsurface aquifer through a specially designed well or basin for future recovery or other environmental benefit. Potable reuse MAR involves treating wastewater effluent to national and state water quality standards using advanced water treatment (AWT) techniques as a source of recharge water. MAR can assist utilities with long-term water supply planning and will play an important role in future water reuse goals for water utilities worldwide.
This webcast summarized the results of Geochemical Considerations for Managed Aquifer Recharge Implementation in Potable Reuse (project 5051). Presenters described a decision framework to evaluate potential physical and geochemical issues anticipated when applying potable reuse for MAR to basins or wells. Utility case studies also demonstrated the supporting decision framework tool, which can help solve common geochemical and physical problems encountered during MAR implementation (e.g., mobilization of metals, clogging, clay conditioning).
