Abstract: A study was made of the populations of intermediate sized interstitial organisms of Del Monte Beach, Monterey, California. In the summer of 1969 this beach was closed because of sewage pollution from the city's offshore outfall. It was expected that populations of organisms constantly exposed to this pollution might be affected. Samples were taken at every 100 meters on a transect running 1000 meters north and 1500 meters south. Counts were substantially lower to the north than to the south. This appears to be correlated to the southerly flow of the sewage as reported by several other investigators. A general enrichment of the environment is considered to account for the increase in population.
