Question
Chapter 11, Problem 1CYE
To determine
To explain: The primary contaminants for which the water is treated.
Expert Solution & Answer
Answer to Problem 1CYE
Municipal water treatment plants treat the water for three different contaminants, namely- primary contaminants, secondary contaminants, and tertiary contaminants. The primary contaminants are comprised of large solid particles.
Explanation of Solution
The term pollution can be defined as the introduction of the contaminants into the environment which causes deterioration of the natural environment. The pollutants can be naturally occurring compound or foreign compounds.
The municipal water treatment plants ensure that the human health is protected, the ecosystem is stabilized and the quality of water is increased. In the primary treatment, the separation of the large solid particles is carried out from the stream in the settling tanks. The suspended dissolved solids are allowed to fall out of the sludge by the settling tanks.

Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day?
