This powerpoint presentation begins by providing background information on waterborne pathogens and goes on to outline topics that include: sources of contamination; index and indicator organisms; defining and interpreting; local, national and international recommendations and standards; and, personal suggestions. Conclusions were that: currently, Escherichia coli is the most reliable microbiological indicator of faecal pollution; no single water quality indicator can meet the diversity of needs for all water sources; "An ounce (gram) of prevention is better than a pound (kilo) of cure"; and, source water protection is an essential intervention strategy in a multi-barrier approach.
