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°to about 200°F.

A method of treating and removing volatile organic contaminants from ground water which comprises treating the water with about 0.1 to 300 parts per million parts of the water of at least one water-soluble sequesterant selected from the group consisting of an organic acid and anionic polymeric sequesterant having an average molecular weight ranging up to about 1,000,000 derived from an unsaturated carboxylic acid monomer, and subsequently adding to said treated water a biocidal amount of at least one oxidizing biocide, and then passing said water through an air stripper to remove volatile organic contaminants with air at temperatures ranging from about 40°to 200°F., wherein said sequesterant and said biocide are added in effective amounts to inhibit the growth and buildup of scale and microorganisms is said air stripper.
