The water may not be different, but it comes to the earth's surface
a bit differently. Ground water in aquifers between layers of
poorly permeable rock, such as clay or shale, may be confined under
pressure. If such a confined aquifer is tapped by a well, water
will rise above the top of the aquifer and may even flow from the
well onto the land surface. Water confined in this way is said to
be under artesian pressure, and the aquifer is called an artesian
aquifer. The word artesian comes from the town of Artois in France,
the old Roman city of Artesium, where the best known flowing
artesian wells were drilled in the Middle Ages. The level to which
water will rise in tightly cased wells in artesian aquifers is
called the potentiometric surface.
Deep wells drilled into rock to intersect the water table and
reaching far below it are often called artesian wells in ordinary
conversation, but this is not necessarily a correct use of the
term. Such deep wells may be just like ordinary, shallower wells;
great depth alone does not automatically make them artesian wells.
The word artesian, properly used, refers to situations where the
water is confined under pressure below layers of relatively
impermeable rock.
Artesian wells are often overexploited because their water is
fresh and easily available, and they eventually become unreliable.
There is also some concern that pollutants such as pesticides or
nitrates can seep into the aquifers.
At the well site there is a plaque telling the History of the
Well Were you will give me some information The well was drilled by
the Winamac Gas and Oil co. in 1887. Your goal is to do two
things.
1.If you want(but not needed) take your picture with the
well,and your GPS at the given Coordinates
2.Tell me (E-mail) two things 1.The depth when the water vain
was struck. 2. And tell me the footage of when drilling was
ceased..
