Question
Answer
Aeration zone   show
๐Ÿ—‘
show Impermeable beds of geologic material that hinder or prevent groundwater movement.  
๐Ÿ—‘
Aquifer   show
๐Ÿ—‘
Aquifer storage and retrieval (ASR   show
๐Ÿ—‘
show exist where the groundwater is bounded between layers of impermeable substances like clay or dense rock. When tapped by a well, water in confined aquifers is forced up, sometimes above the soil surface. This is how a flowing artesian well is formed.  
๐Ÿ—‘
show Putting water back into groundwater storage from surface water supplies such as irrigation, or induced infiltration from streams or wells. Includes aquifer storage and retrieval (ASR).  
๐Ÿ—‘
show Streamflow coming from groundwater seepage into a stream or river. Groundwater flows underground until the water table intersects the land surface and the flowing water becomes surface water in the form of springs, streams/rivers, lakes and wetlands.  
๐Ÿ—‘
Best management practices (BMPโ€™s)   show
๐Ÿ—‘
show Mixed fresh and salt water.  
๐Ÿ—‘
show Capillary water moves upward from the water table in the aeration zone by capillary action. This water can move slowly and in any direction. While most plants rely on water from precipitation in the unsaturated zone, their roots may tap into capillary h20  
๐Ÿ—‘
Collection site   show
๐Ÿ—‘
show The process in the hydrologic cycle by which a vapor becomes a liquid; the opposite of evaporation.  
๐Ÿ—‘
show Pumping from a well in a water table aquifer lowers the water table near the well. This area is known as a cone of depression. The land area above a cone of depression is called the area of influence. Groundwater flows towards the cone of depression.  
๐Ÿ—‘
show (aka artesian or pressure aquifers) Groundwater that is bounded between layers of impermeable substances like clay or dense rock. When tapped by a well, water in confined aquifers is forced up, sometimes above the soil surface.  
๐Ÿ—‘
show Geologic material with little or no permeability or hydraulic conductivity. Water does not pass through this layer or the rate of movement is extremely slow.  
๐Ÿ—‘
show The use of water-saving methods to reduce the amount of water needed for homes, lawns, farming, and industry, and thus increasing water supplies for optimum long-term economic and social benefits.  
๐Ÿ—‘
Consolidated rock   show
๐Ÿ—‘
show Reducing the water supply (i.e., removing water from a river, lake or aquifer) without returning an equal amount. Examples include water intake by plants, humans, and other animals and the incorporation of water into industrial or food products.  
๐Ÿ—‘
Contaminant   show
๐Ÿ—‘
show Groundwater movement equation developed by Henry Darcy in the mid-1800โ€™s.  
๐Ÿ—‘
Depletion   show
๐Ÿ—‘
show The movement of a substance from an area of high concentration to an area of low concentration.  
๐Ÿ—‘
show An outflow of water from a stream, pipe, groundwater aquifer, or watershed; the opposite of recharge.  
๐Ÿ—‘
show The area or zone where groundwater emerges from the aquifer. The outflow maybe into a stream, lake, spring, wetland, etc.  
๐Ÿ—‘
Drawdown   show
๐Ÿ—‘
show An extended period with little or no precipitation; often affects crop production and availability of water supplies.  
๐Ÿ—‘
