Summary Introduction
Introduction:
Water treatment is the process of treating water to improve its quality and make it suitable for use. Water contamination is the presence of any substance, whether it is natural or artificial, in water which makes it unsuitable for use. Drinking water contains low level of microbes are not harmful if consumed. Coliform is a Gram-negative bacteria, which is present in water that is polluted due to “fecal contamination”.

- 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?arrow_forwardwater sample could be (-) for coliforms when tested by PMF method, could this water still be a major public health threat and why?arrow_forwardDiscuss the THREE (3) main stages crucial to microbial leaching of copper from a low-grade ore, indicating the reactions where necessary.
