Outside at the well-head a small low-voltage air pump is attached to the well casing. A pipe with an aeration section is inserted into the well bore, down to the bottom of the well. Pressurized air is fed into this pipe causing water that was at the bottom of the well to be air-lifted to the top of the water column. This recirculation of the water oxidizes the water contaminants in the well. Otherwise trapped gasses like Radon and Methane escape. Contaminant minerals come out of solution and drop harmlessly to the bottom of the well. If this sounds really simple, good, it is.Pro:
Simple. Less expensive than Bubble-up approach. Easy Home-Owner maintenance. Cheap to run. Quiet.Con:
If you have Radon levels over 100,000 pCi/L, Certain combinations of water chemistry (rare)
