Abstract: A study wsa conducted on the coliform distribution in seawater samples and in M. californianus (conrad, 1837) for Carmel Bay, Calif. Populations of Mytilus were small in areas where effluent concentration was large. No adults were found in the immediate vicinity of the outfall. Determination of coliform levels in M. californianus was unsuccessful. Coliform concentrations could not be correlated with direction of effluent for distances over 270 feet. Onshore coliform counts were predominantly higher than offshore samples. A rise in coliform counts occurred toward the end of May.
