sand and gravel particles in a water bearing zone, known as an aquifer. This aquifer is the well driller's target. Once you drill into the aquifer, a screen must be installed at the bottom of the casing to keep sand and gravel out and let the water into the well. With no screen, the sand could quickly destroy the pump and plug the well.Web
