Aquifer storage and recovery (ASR) is the direct injection of surface water supplies such as potable water, reclaimed water (i.e. rainwater), or river water into an aquifer for later recovery and use. The injection and extraction is often done by means of a well.
There are regulatory storage-type aquifer recovery and storage systems which when water is injected into it gives the right to withdraw the water later on. [2] Groundwater banking has been implemented into semi-arid and arid southwestern United States because this is where there is the most need for extra water. [2]
The two water supply options being considered assume aggressive conservation targets for homes and businesses, wastewater reuse, and aquifer storage and recovery. These options are: [20] [22] A 40-foot (12 m) dam raise at Henry Hagg Lake with a raw water pipeline pumpback.
Aquifers of the United States Withdrawal rates from the Ogallala Aquifer.. This is a list of some aquifers in the United States.. Map of major US aquifers by rock type. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
Unconfined aquifers have storativities (typically called specific yield) greater than 0.01 (1% of bulk volume); they release water from storage by the mechanism of actually draining the pores of the aquifer, releasing relatively large amounts of water (up to the drainable porosity of the aquifer material, or the minimum volumetric water content
Some aquifers, like the Edwards Aquifer In Central Texas, respond really quickly to precipitation. ... Another is aquifer storage and recovery, where you take water, pump it down into an aquifer ...
Effects of climate change could have different impacts on groundwater storage: The expected more intense (but fewer) major rainfall events could lead to increased groundwater recharge in many environments. [18]: 104 But more intense drought periods could result in soil drying-out and compaction which would reduce infiltration to groundwater. [21]
Directs the Army, the Federal Emergency Management Agency (FEMA), Environmental Protection Agency (EPA), and the heads of other appropriate Federal agencies to assist Oregon in developing and implementing a comprehensive basin-wide strategy in the Willamette River basin.
