Managed Aquifer Recharge (MAR) can be utilized to convey sources of water into the subsurface for storage, potential reuse, augmentation of water supplies, and protect against salt water intrusion. The risks to groundwater quality from the use of MAR are poorly understood. In order minimize risks to groundwater quality, site  characterization is critically important. In addition, long-term monitoring needs and stakeholder concerns should be considered upfront for successful MAR implementation and long-term performance needs.

This presentation will inform NGWA members of EPA's implementation of a MAR project addressing the characterization needs and outreach needs. The initial planning is key to address regulatory needs, stakeholder concerns, development of contingency plans to address potential problems, and balancing characterization needs with costs.
