1. “Coliform bacteria are the only group of micro-organisms considered suitable for themonitoring of faecal pollution.”Is the statement above still valid? Motivate your answer and briefly describe at two othertypes of indicator organisms.
2.
Every year, supposedly safe municipal water supplies cause outbreaks of enteric illness.Using the Wisconsin outbreak example from the 1990s, explain how pathogens can slip through water analysis and treatment processes undetected and untreated.
3. Why not test water samples directly for Salmonella typhosa or other pathogens?
