What is an Artesian Well?

It is a drilled well through which water is forced upward under hydrostatic pressure. The water in an artesian well flows from an aquifer, which is a layer of porous rock, capable of holding and transmitting quantities of water.

How is an Artesian Well Properly Constructed?

To create an artesian well the first process is to drill down through the topsoil or overburden, this can consist of loam, sand, rocks, gravel, clay, etc., until the drill reaches what is called ledge or bedrock. At this point we continue to drill into the ledge far enough to ensure it is a good solid formation. Now the well casing will be set down through the hole in the overburden into the ledge. A good seal into the ledge is the most important part of the process. This is what keeps surface contaminates from entering your well. Once the well casing is set into the bedrock using a drive-shoe well seal we can start drilling for water within the bedrock. At this point we use a percussion drill that will go down through the casing until it strikes bedrock. Now as we drill down through the rock it will make its own casing. This will hold and store the water that comes from within the rock. As the drill goes down it goes through different layers of rock as well as cracks, voids, and fracture zones. These different layers and cracks can carry water through them. Once they are drilled into, the water, which is under hydrostatic pressure, will follow the easier path into the well, creating a closed source of water that can supply your home or business.
