Mining the Underground Water Aquifer

Mining the Aquifer When a natural resource like iron or gold is mined, it's usually taken out of the ground and never replaced. Groundwater is a different type of natural resource. It can be replaced. Gradually, rain that gets trapped in the soil (instead of running off into rivers) will percolate down until it reaches the gravel and

Aquifer Wikipedia

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater can be extracted using a water well.The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or aquifuge

Issue Paper: Sand And Gravel Mining

Sand and gravel mining within an aquifer recharge area will, at a minimum, increase the vulnerability of an aquifer to be contaminated because it decreases the distance between the ground water table and land surface. In some cases, the excavation actually penetrates the shallow aquifers, creating a pond or lake and a direct access to ground water.

Clean sand is stockpiled until it can be loaded into trucks for final sorting and drying off-site. (Some mines sort and dry sand on-site rather than sending it out.) Because the sand still contains moisture when it is stockpiled, drain tiles beneath the piles channel water to a lined process-water pond.
