Question
Chapter 52, Problem 1CA
Summary Introduction
To analyze:
Water sample with high coliform count.
Diseases which can be prevented by chlorinating the water.
Introduction:
Coliform bacteria are the indicator organisms which are present in the contaminated water. They help in analyzing the water quality.These bacteria are also found in feces of warm-blooded animals and humans. Their presence in water indicates the presence of illness causing agents.

1. How many coliforms need to be present before drinking water is considered dangerous?
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.
What is the only acceptable level of coliforms in drinking water?
