Abstract: The rocky headland known as Point Pinos, Monterey County, Cal., receives approximately 1.5 million gallons of primarily treated sewage daily. Adjacent areas to the sewage outfall mouth, located intertidally, are visibly deficient in fauna and flora typical of the rocky Monterey coast. The purpose of this six week investigation was to determine whether the sewage effluent affects the bacterial and diatomaceous films known to produce a substratum for the metamorphosis of attached invertebrate larvae. The importance of this early film to invertebrate larval attachment has been debated for many years. The study described here attempts to correlate variations in microfilm formation with proximity to the Pacific Grove sewage outfall.
