A well water aeration system removes volatile contaminants from well water pumped through the well pipe of a well into a building. An elongate spray conduit is spliced into the well pipe at a location below the top of the well but above the average static water level in the well. The spray conduit is formed with spray holes for spraying, aerating and recirculating a fractional portion of the well water pumped through the well pipe with the fractional portion of sprayed water falling back down the well. The spray holes are selected in number and diameter to maintain adequate pressure for continued pumping of the well water through the well pipe. A check valve at the upper end of the spray conduit stops the backflow of water from the building into the elongate spray conduit when pumping of well water through the well pipe stops. Water in the spray conduit empties through spray holes at the bottom end of the spray conduit leaving a pocket of air in the conduit when pumping of well water through the well pipe ceases. When the pressure gauge at the water tank in the building calls for more water and pumping resumes, the air pocket is expelled through the respective spray holes at the top of the spray conduit voiding the contaminant-laden air and preventing such air from entering the building through the water supply. An elongate aeration conduit of greater diameter encloses the spray conduit so that well water sprayed through the spray holes deflects from the walls of the aeration conduit for greater aeration.

A method for aerating well water pumped through a well pipe of a well to a building comprising: providing spray holes in the well pipe at a location below the top of the well and above the average static water level in the well; spraying and aerating a fractional portion of the well water pumped through the well pipe from the well and permitting said fractional portion of well water to fall back down the well; and checking the runback of water in the well pipe from the building above the spray holes when pumping of water in the well pipe stops.
