A water well refers to an excavation that is made into the ground for the purpose of accessing groundwater contained in underground aquifers. The excavation or structure is constructed through boring, digging, drilling, or driving using mechanical or manual means. The water contained in wells may be pumped out using machines or may be drawn using buckets and other forms of containers by hand. When in need of the best water well services TX is the right state to visit.
According to historic evidence, the first well was constructed over eight thousand years ago. The structures varied widely in sophistication with some comprising of simple scoops constructed on dry watercourses. Conversely, others incorporated a high level of sophistication and size that they powered civilizations and livelihood in various ancient cities. Some major examples of sophisticated wells include the ganats of Persia and the shadoofs, sakiehs, and Stepwells of India.
Many and diverse kinds of wells exist today. Drilled, drilled, and dug wells are some of the most common examples. In ancient times, the most common type was the dug well. These structures were a source of livelihood to many people and they powered civilizations. They supplied potable groundwater but lacked pumps. In most rural areas, dug wells are still very common.
Driven wells are constructed using a well hole structure. The structure is comprised of a screen and a hardened drive point. A tripod and a driver are used to hammer the drive point into the ground. Pipe sections are added to the system as necessary. Upon encountering the groundwater, all sediment created is washed from the well before a pump gets installed.
Various means are used to construct drilled wells. The most commonly used ones are table rotary, top-head rotary, and use of cable tool drilling equipment. These means use a drilling stem which has to be turned for the formation of a cutting action. Either machine of hand may be used to do the excavation. Hand drilling techniques include augering, sludging, hand percussion, jetting, and driving. On the contrary, machine drilling techniques include rotary, hammering, and percussion.
Two broad categories of drilled wells exist, that is, unconfined/shallow and deep/confined wells. Like the name suggests, shallow wells are only limited to the uppermost aquifer. On the contrary, deep wells are very deep and reach aquifers that are placed between two strata. Another classification of wells bases on what use they are put to. Under these classification, the two key categories are monitoring and production/pumping wells.
Various pieces of information about the area must be determined before excavation of any well begins. Some of the factors that must be determined include water table depth, rate, recharge area, seasonal fluctuation, and geology. Determination of these factors is the work of either hydrogeologists or groundwater surveyors. Some of the tools and methods used to find this information include geophysical imaging, geologic maps, and electro-seismic surveying.
Shallow sources can supply potable groundwater at an affordable cost. However, contamination from different sources remains a major problem, which poses a health risk to people. Contaminated wells can spread a lot of waterborne diseases. In the US, driven and dug wells are considered unreliable water sources.
