In cooperation with the Marin County Department of Public Health, an intensive sampling program of Bolinas Lagoon and Bay was conducted to determine how extensively the receiving waters were affected by the raw sewage discharging from the Bolinas Town Site. Bacteriological samples of shellfish and receiving waters were collected in the immediate vicinity of the discharge and from the Stinson Beach State Park east of the outfall, to a point half-way between the lagoon mouth and Duxbury Point, west of the outfall. The field study began July 4, 1970 and ended July 15, 1970. Sewage solids were observed in the vicinity of the Bolinas Town discharge; on adjacent ocean beaches; and on the nearby sand islands in Bolinas Lagoon. Results of bacteriological analysis of water and shellfish confirm the presence of sewage in these areas. Both shell fishing for human consumption and water-contact sports take place in the areas found to be adversely affected by the Bolinas raw sewage discharge.

Ecologists have two long-standing ways to study large ecosystems such as lakes, forests, and salt-marsh estuaries. In the first, which G. E. Hutchinson has called the holological approach, the whole ecosystem is first studied as a "black box," and its components are investigated as needed. In the second, which Hutchinson has called the merological approach, the parts of the system are studied first, and an attempt is then made to build up the whole from them. For long-term studies, the holological approach has special advantages, since the general patterns and tentative hypotheses that are first worked out help direct attention to the components of the system which need to be studied in greater detail. In this approach, teams of investigators focus on major func tions and hypotheses and thereby coordinate their independent study efforts. Thus, although there have been waves, as it were, of investigators and graduate students working on different aspects of the Georgia salt-marsh estuaries (personnel at the Marine Institute on Sapelo Island changes every few years), the emphasis on the holo logical approach has resulted in a highly differentiated and well-coordinated long-term study. Very briefly, the history of the salt-marsh studies can be outlined as follows. First, the general patterns of food chains and other energy flows in the marshes and creeks were worked out, and the nature of imports and exports to and from the system and its subsystems were delimited.
