CHEMICAL, BIOLOGICAL, and ENVIRONMENTAL FACTORS RESPONSIBLE for the EARTHY ODOR in the AUBURN CITY WATER SUPPLY J. D. WEETE, W. T. BLEVINS, G. R.WILT, and D. DURHAM' INTRODUCTION Background On Odors Of Biological Origin in Water HE OCCURRENCE of objectionable odors in water used for drinking and commercial purposes is well documented in certain regions of the United States (1, 4, 12, 15) and various other parts of the world. (1, 8, 9, 11). Odors in sur- face waters may originate from industrial and municipal sewage effluents or from biological activities of algae or heterotrophic microorganisms. Odors of biological origin may be due to decomposition of organisms or to the produc- tion of microbial metabolites.
