Artificial Recharge: Process of adding water to an aquifer for the purpose of restoring or managing groundwater resources. Example, restoring shallow groundwater levels to their past elevations.

Aquifer Storage and Recovery (ASR): Process of capturing water during time of excess (example, spring time river flows), treating it to drinking water standards, injecting into deep aquifers that function as large storage reservoirs. ,[object Object]

What is ASR? Water is captured from a source recharged into an aquifer stored recovered for use used Source: NAS

Artificial Recharge Purposes Conserve and dispose of runoff and flood waters; Supplement the quantity of ground water available; Reduce or eliminate decline in the water level of ground water reservoirs; Reduce or balance salt water intrusion; Store water to reduce costs of pumping and piping; Store water in off-seasons for use during the growing seasons; Conserve energy in geothermal applications; and, Remove suspended solids by filtration through the ground.

Why ASR ? Provide longer term storage of water resource – helps with restoration; Cost effective compared to surface reservoirs (e.g., water not subject to ET); Provides effective means to provide water for ecological restoration purposes (“in-stream” uses), water supply and agricultural use; Long experience in USA; Flexibility in well siting/minimal real estate; and, Easier to secure and protect from purposeful destruction or contamination.

“Begin with the End in Mind” – ASR Uses Emergency water supply; Seasonal water supply or help meet peak demands; Agricultural use using “lesser quality” of water; Ecological use to meet minimum flows and levels; Improve water quality in an unproductive aquifer; Minimize salt-water intrusion along the coasts or from deeper aquifers; Reduce subsidence; and, Disinfection By-product or nutrient reduction.

A Bit of ASR History Concept developed in Israel, USA, and Australia over last 30 years; Much theoretical work completed by Louisiana State U, U Florida, and U Wisconsin (1966 to 1980); First USA ASR project – Wildwood, 1968; First Florida ASR project – Manatee/Peace River, 1983; “High Plains States Artificial Recharge Act” – 1983; and, USGS/COE studies in 1983 to 1985 on south Florida ASR in brackish water aquifers.

Regulation of ASR Projects Regulated under the Safe Drinking Water Act, Underground Injection Control (UIC) Program; ASR wells are under “Class V” wells in UIC program; and, Programs regulated by primacy states or the US EPA; First UIC permit is typically a “construction or testing” permit good for 3 to 5 years; and, After that owner can apply for an extension of testing period or an operational UIC permit.

Is ASR a Viable Option in Michigan? ,[object Object]

Numerous projects in the United States recharge excess surface water into land application basins or into injection wells;

Cost effective and innovative water management option;

Hydrogeology in Michigan is compatible with ASR projects; and,

Has been used across the United States successfully.,[object Object]

ASR Myths ASR is an unproven technology; ASR is the best technology ever !!; Reality – ASR has been utilized in the USA and worldwide. As with any technology, there have been notable successes and a few failures.

ASR Myths ASR is very costly; ASR is inexpensive; Reality – ASR costs can fall within a rather large range. Cost optimization can minimize the costs and maximize the benefits. Typical costs in the $1 to $2 per thousand gallons water recovered.
