Shallow Wells and
Deep Artesian Wells
Deep Artesian Wells
STAINING & WATER QUALITY
Generally, good water quality is obtained from wells drilled into the deep formations. However, good water quality can often also be obtained, in some areas, from the shallow and intermediate depth aquifers. The quality of the water obtained from a well is dependent upon the natural mineralization in the ground. There is no way for a well driller to know exactly what the water quality will be in any well, even though he may have drilled nearby. The direction of flow of the water in the aquifer to the well often changes from well to well and any natural minerals dissolved in the water will therefore be pumped to the surface.
In some areas, there will be a strong smell of “sulfur”. This is a naturally occurring mineral which is more of a nuisance than a danger and in most cases will not cause any staining problem, providing the well casing, piping and connections are constructed using “PVC PLASTIC”. Wells constructed using STEEL casings, whether shallow or deep, will often show staining on sidewalks and walls that looks like “black ink” or “red rust”. Additionally, the interior of the casing will clog up with mineral deposits. This is a reaction of the sulfur gas on the metal of the casing or the natural plating of the mineral on the steel casing. The average life span of a steel well will be about 10 years.
Occasionally, there will be an orange staining that may come from the minerals in the deep aquifer itself. That mineral is generally a very small concentration of iron. The staining will be minimal in most cases.
In some areas, salt content in the water from deep wells may be high enough to affect plants and grass.
LIMESTONE PARTICLES IN THE WATER
The deep wells are drilled into a limestone formation. There is no screen on the bottom of the casing because the water is derived from the cracks in the limestone. In a freshly drilled well, small pieces of limestone and shells that comprise the formation may be dislodged during the drilling process. These particles will float up in the water as the well is pumped. The well driller will attempt to pump and clear out most of the loose limestone at the time that he develops the well. Often a small filter is provided on the suction side of the pump to capture these particles. After a time, as the well is pumped, the particles will clear. This filter must be cleaned on a regular basis until the well clears naturally.

PLASTIC CASING
Our company uses “PVC PLASTIC” casing in the construction of their drilled wells. The casing is installed by actually drilling a hole in the ground to the proper depth and then carefully setting the casing into surficial sand & gravel aquifers, the Hawthorne Clay or the Floridian limestone without the use of a hammer. We carefully grout the annular space around the PVC casing with cement grout in strict conformance with the DEP drilling code. This is necessary so that water from the ground surface or the upper aquifer does not filter down into the lower aquifer and also that the artesian flow does not leak to the surface alongside of the casing.
PVC cased wells are not subject to the corrosion or mineral buildup effects of the sulfur gas and will therefore last considerably longer than steel cased wells.
