I spent a year in Port Deposit, MD back in the thirties, in a house that had an artesian well.
The well was perhaps thirty feet ll below the level of the hill behind the house, and a continuous
5 gallons or more of water flowed from the faucet constantly, day and night. I was told that it was
an artesian well, but it was a long time before I knew the origin of the name.

artesian - 1830, from Fr. artésien "of Artois," French
province where such wells were first bored 18c.

A tilted porous rock layer ran from the house upwards under the hill behind it.

we had to put in a well about a year ago, due to the drought in Vermont. our wonderful spring dried up(it has since returned though now it is our back up source). our well was drilled to a depth of 400 feet. we get 2 gallons per minute, and had to take out a home equity loan to pay for it. we truly understand what a precious resource our freshwater is.
