Two studies were carried out over several seasons to ascertain the survival of pathogenic, indicator, and tracer bacteria in membrane filter chambers. The survival times for these bacteria were lengthy (≥77 days) under either summer or winter conditions. Thus, the use of seasonal effluent disinfection might eventually result in bacterial contamination of downstream sediments and possibly of waters overlying these sediments. As a result of certain disturbances, these bacteria could be recycled throughout the water column and eventually into man or animals directly or indirectly through potable water supplies.
