Liquid wastes in transit often are accompanied by malodorous volatile materials which emanate from sewer vents into the surrounding atmosphere. Many of these materials are perceptible in very low concentrations in the range of parts per billion. Disagreeable odors associated with the transporta tion of wastes are of serious concern to the responsible regulatory and con trol agencies and to the citizens in the vicinity where these odors are dis cernible. These odor problems are intensified by warm summer tempera tures, by long detention times in tran sit, by lack of aeration, and by the close proximity of residences to sewer system vents. Pomeroy (1) (2) and Mayo (3) have alleviated sewer odor problems successfully by routing exit sewer gases through soil beds. Mayo's installation on Mercer Island at Seattle has per formed so effectively that the consult
