Soap removal from borewell

After several failed attempts at retrieving a stuck bore pump from 360 feet in a bore well, our mechanic poured 3kg of washing soap powder into the borewell to ease out the retrieval process as a last option. Finally, we did not succeed in retrieving the pump. During drilling, first water source found at 150 feet and we were stuck after this and were unable to pass from this depth. Our rope, hose and wires were all broken during the retrieval. Now we are lifting water from 150 feet with an air compressor lifting method. Now the problem is that water is coming up with soap foam for last 20 days and still continues. How can we neutralize soap in the borewell without damaging the water quality for drinking? Kindly advise.
