Sand and Gravel Mining: Effects on Ground Water Resources in Hancock County, Maine, USA ... How the mining of sand and gravel affects aquifers and change aquifer vulnerability to .
An aquifer is an underground layer of waterbearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater can be extracted using a water study of water flow in aquifers and the characterization of aquifers is called terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or aquifuge ...
In many aquifers, ground water is pumped from pore spaces between grains of sand and gravel. If an aquifer has beds of clay or silt within or next to it (figure 2), the lowered water pressure in the sand and gravel causes slow drainage of water from the clay and silt beds. The reduced water pressure is a loss of support for the clay and silt beds.
Mar 03, 2013· Also, sand mining within an aquifer recharge area will increase the vulnerability of the aquifer to be contaminated because it decreases the distance between the .
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 ...

Mining applications. By subjecting core samples of aquitards to geocentrifuge testing, researchers can help determine how much water or contaminant will move into or out of an aquifer once it is disturbed by drilling or pumping.
Clean sand is stockpiled until it can be loaded into trucks for final sorting and drying offsite. (Some mines sort and dry sand onsite 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 processwater pond.

Another multistoried building coming up has emptied the wells of several residents and pumped groundwater out to build the ubiquitous car parking basement. All the efforts of an entire community to harvest rainwater and recharge the shallow aquifer can come to nought with one such building, or one tanker operator emptying the aquifer.
Aquifers are underground layers of porous and permeable rock or unconsolidated sediment, such as sand and gravel, that hold water. Porous means that rocks contain pores, or holes, and permeable means the pores are interconnected in a way that allows water to flow from pore to pore. Spaces containing water in sand and gravel or loosely consolidated rock can be relatively large while pores or ...
