Its aim is to reduce to an acceptable level the intensity of malodors in an affected community. An odor-abatement strategy is presented for handling the expected range of odor conditions at dredged-material disposal sites. Although significant problems with malodors were not observed beyond the disposal-area dikes during site visits, noteworthy odor episodes had occurred at some sites. Odorous compounds in the air samples were identified by gas chromatography/mass spectrometry, while the detection threshold, intensity, and character of the various odors were determined by experienced panelists using a dynamic, forced-choice-triangle olfactometer. Samples of malodorous air and dredged material were collected at diked disposal sites at the following locations: Buffalo, NY Milwaukee, WI Mobile, AL York Harbor, ME Houston, TX Detroit, MI and Anacortes, WA during the period July-October, 1975.
