An air‐stripping tower was designed to treat 1500 gpm (0.09464 m 3 /s) of groundwater contaminated with trichloroethene, tetrachloroethene, cis ‐1, 2‐dichloroethene, toluene, ethyl benzene, and isomers of xylene. A simplified procedure for designing a tower with the smallest volume and energy requirements was used. Data for the first four months of operation demonstrated excellent removals for the six volatile organic compounds. The cost of treatment was about $0.0586/1000 gal (3.785 m 3 ) of water treated. Operating problems, microbiological analyses, and data regarding total organic halogen (TOX) and TOX formation potential are summarized.
