Abstract
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.
