Chapter 31, Problem 1RQ
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.
Expert Solution & Answer
Explanation of Solution
The two major classes of water include potable water and recreational water. Water which is suitable for the consumption of human beings is referred to as potable water. Filtration and chlorination process are the two important processes which are carried out in potable water to make it safe for consumption. Recreational water includes aquatic freshwater systems such as a stream, lakes, ponds, as well as public wading and swimming pools. This recreational source of water acts as a major cause of waterborne illness and causes more disease outbreaks as compared to drinking water.
Surface water can be made safe for drinking purposes through the process of filtration and chlorination. Both these process make the surface of recreational water just like of potable water.

- The party primarily at fault for the water crisis in Flint, Michigan was the governmental agencies. The two main government agencies at fault are the Michigan Department of Environmental Quality and the Environmental Protection Agency, they failed to properly monitor and respond to the major issues that came up involving the water quality, despite receiving very early evidence of there being contamination (Sullivan, 2017). Although others, including city officials and water treatment personnel, share some blame, it was the systemic failures within governmental bodies that allowed the crisis to escalate. Regaining public trust after a significant blow requires transparency, accountability, and meaningful action. Being transparent with the public involves providing accurate information, and letting the public be fully aware of the inter-workings of governmental agency actions. Being accountable involves acknowledging past mistakes, such as putting out a statement admitting fault to how…arrow_forwardName the various communicable diseases spread by way of polluted water.arrow_forwardWhich of the following are properties of good indicator organisms for water quality?
