Managed aquifer recharge (MAR) is the purposeful recharge of water to aquifers for subsequent recovery or for environmental benefit. MAR supports water supply resiliency. MAR is a well-developed groundwater technology increasingly used
for water security around the world and across the United States.
Categories of MAR include:
- Aquifer storage and recovery (ASR) — injection of water into a well for storage in the aquifer and subsequent recovery from the same well
- Aquifer storage, transfer and recovery (ASTR) — injection of water into a well for storage in the aquifer and recovery from a different well, generally to provide additional water treatment
- Recharge pond or basin — a surface facility, often a large pond, used to increase the infiltration of surface water into a groundwater basin; basins require the presence of permeable soils or sediments at or near the land surface and an unconfined aquifer beneath
