ABSTRACT:
A method of treating and removing volatile organic contaminants from ground water by treating the water with effective amounts of a water-soluble polymeric sequesterant comprising polymers derived from acrylic acid or organic acid, followed by the addition of a biocide, e.g., chlorine, and then subsequently passing the treated water through a packed column or air stripper wherein the volatile organic contaminants are removed by passing air in a counter-direction to the flow of water at temperatures ranging from about 40.degree. to about 200.degree. F.
