Abstract: Fecal coliform data collected by various government agencies and the university community between 1970 and 1977 were reviewed. In order to organize and compare data from different areas of the Fraser River estuary, over 100 sampling sites were grouped into 22 river reaches. The data indicated an obvious improvement in microbial water quality subsequent to the start-up of the Annacis Island sewage treatment plant in 1975. Chlorination of sewage treatment plant effluents during the summer reduced fecal coliform counts below winter levels and provided acceptable water for irrigation and swimming at Spanish Banks beaches, adjacent to the study area. It was concluded that because of the diversity of inputs, which include storm sewers and upstream sources, the elimination of bacteriological contamination of molluscan shellfish in the estuary was not presently feasible. A rough comparison of coliform loadings from sewage treatment plant (STP) effluents, storm sewer effluents, and the Fraser River upstream of the stu
