A contaminant which is harmful to people, and other living things, is always defined as: A. a point source of pollytion (like heavy metal particulates from the Sudbury smokestacks B. a toxin (like radioactive cesium-137 leaking into seawater around Fukushima, Japan) C. a non-point source of pollution (like petroleum products from city streets) D. an area source of pollution (like pesticide runoff from agricultural fields) E. a mobile source of pollution (like exhaust fumes from cars and trucks)Discuss the microbial ecology contributing to crowncorrosion of concrete sewer lines. In considerationof this ecology, what intervention strategies might beuseful in reducing or eliminating corrosion?
- 10) Discuss the use and over-utilization of surface and ground water.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?Explain the manner in which pollution is caused by solid industrial waste, industrial effluents and industrial waste gases.
