  2. Artesian well - Wikipedia

    en.wikipedia.org/wiki/Artesian_well

    An artesian well is a well that brings groundwater to the surface without pumping because it is under pressure within a body of rock or sediment known as an aquifer. [1] When trapped water in an aquifer is surrounded by layers of impermeable rock or clay, which apply positive pressure to the water, it is known as an artesian aquifer . [ 1 ]

    en.wikipedia.org/wiki/Groundwater-related_subsidence

    Groundwater-related subsidence is the subsidence (or the sinking) of land resulting from unsustainable groundwater extraction.It is a growing problem in the developing world as cities increase in population and water use, without adequate pumping regulation and enforcement.

  5. Floridan aquifer - Wikipedia

    en.wikipedia.org/wiki/Floridan_Aquifer

    The Upper Floridan aquifer is the main source of water withdrawn from the Floridan aquifer system due to high yields and proximity to land surface. Groundwater in the Upper Floridan is fresh in most areas, though locally may be brackish or saline, particularly in coastal areas with saltwater intrusion problems, and in South Florida. The Upper ...

  6. Cone of depression - Wikipedia

    en.wikipedia.org/wiki/Cone_of_depression

    In confined aquifers , the cone of depression is a reduction in the pressure head surrounding the pumped well. When a well is pumped, the water level in the well is lowered. By lowering this water level, a gradient occurs between the water in the surrounding aquifer and the water in the well. Because water flows from high to low water levels or ...

  7. Death of Alfredo Rampi - Wikipedia

    en.wikipedia.org/wiki/Death_of_Alfredo_Rampi

    Around 19:00 on 10 June 1981, the 6 year-old boy Alfredo was out on a walk with his family. When the family decided to return home, he asked his parents if he could walk alone and as the child wandered by himself he fell into an artesian well which was very narrow and deep (about 30 cm (12 in) wide and 80 m (260 ft) deep).
