Chapter 5: Ground-Water Flow to Wells
"Wells are one of the most important aspects of applied hydrogeology. Water wells
are used for the extraction of ground water to fill domestic, municipal, industrial,
and irrigation needs. Wells have also been used to control salt-water intrusion, remove
contaminated water from an aquifier, lower the water table for construction projects, relieve
pressures under dams, and drain farmland. Wells also function to inject fluids into the ground.
On Long Island, New York, all ground water pumped for cooling purposes must be returned
to the same aquifier by an injection well. Still another function of wells is to
dispose of wastewater into isolated aquifiers. Finally, as a means of ground-waste
management, wells are sometimes used to artificially recharge aquifiers at rates greater
than natural recharge."
