Description
Summary:The results of a survey in the Southern California Bight indicated that much of the floatable particulates in the vicinity of primary treatment outfalls originated in wastewater. Most of the particulates of this origin were composed of grease and wax. These particulates also contained appreciable concentrations of coliform bacteria. The particulates from primary effluents had large proportions of unsaturated 18-carbon fatty acids, whereas secondary effluent particulates resembled open-ocean particulates in proportions of fatty acids. Larger particulates were quickly dispersed. Surface concentrations of 3-mg hexane-extractable matter/${\rm m}^{2}$ or less probably are aesthetically acceptable.
