A domestic well water system, rendered unusable by volatile contaminants in the groundwater, can be restored to use by installing an aerator in a flow path such that water is continuously pumped, by the existing well pump, out of the well, through the aerator, and back to the well through the well head. Water is diverted from this flow path for use. The well serves as a storage device, and water returned from the aerator to the well mixes with water in the well and serves as a buffer to encroachment by contaminated groundwater.

A process for obtaining delivery of purified water from a well where the groundwater feeding the well contains contaminants comprising the steps of: pumping water from the well through the well head and through a flow path which passes through a water treatment unit and returns to the well through the well head; removing, by means of said water treatment unit, at least a portion of the contaminants from the water in said flow path, as the water flows through said unit; returning purified water from the water treatment unit to the well through the well head, whereby the well serves as a storage device for the returned water, and the returned water mixes with water in the well and serves as a buffer to encroachment by contaminated groundwater; and delivering a portion of the water in the well to a point of use.
