Abstract: The effect of primary treated sewage on the distribution and abundance of microfauna found associated with three species of algae, characteristic of the low, mid, and high intertidal, was studied. The results show that the sewage effluent affects the distribution of microfauna most strongly in Prionitis lanceolata and Corralina vancouveriensis, algae representatives of mid and low intertidal species. Microfauna associated with Endocladia muricata, the representative alga of the high intertidal, was affected only in the immediate region of the outfall. Information from current studies and chemical-physical assays in the study area allowed a hypothesis of effluent dispersal and effect to be made. Certain species, by their presence or absence on algae in the immediate outfall area, seem to be possible indicators of marine pollution.
