Mining the Underground Water Aquifer - Living History Farm

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 sand layers that will hold it underground. The problem is that the ...

Most shallow aquifers in sand and gravel deposits produce lower yields, but they can be rapidly recharged. Some deep aquifers are known as “fossil waters”. The term “fossil” describes water that has been present for several thousand years. These aquifers became saturated more than 10,000 years ago and are no longer being recharged. Water does not remain immobile in an

GRAVEL AQUIFERS: INVESTIGATION, DEVELOPMENT PROTECTION

Gravel aquifers occur in Ireland in a variety of geological environments and are exploited not only by boreholes but also by springs, dug wells, infiltration galleries and well points. Among the notable advantages of gravel aquifers are their high permeabilities, high storage coefficients, good filtration and attenuation characteristics and low flow velocities. Among their perceived ...
