Chapter 32.1, Problem 1CR
Summary Introduction
Quality of water is a very important factor which helps to ensure public health. Contaminated water is the source of various types of waterborne diseases. Various types of waterborne illness occur due to untreated or poorly treated water which is used for drinking or food preparation purposes.

Coliforms are commonly used as an indicator of drinking water quality. As we discussed, in March and April of 1993 there was a major outbreak of gastrointestinal illness in Milwaukee, Wisconsin caused by contamination in the public drinking water supply. As summarized by MacKenzie et al.1, “throughout the period from February to April 1993, samples of treated water from both (water treatment) plants were negative for coliforms and were within the limits set by the Wisconsin Department of Natural Resources for water quality.” Why, in this case, did coliforms remain at acceptable levels despite water contamination that resulted in over 400,000 cases of gastrointestinal illness?
Some cities have strict controls in place to address stormwater pollution and are working to separate storm sewers from sewer systems that carry human waste. Do you think it is fair for a city to pass such ordinances to protect water quality and ensure an adequate water supply?
why is it important to have an access of clean and safe drinking water?
