When water used to control to cool power plants during normal operations is released into adjacent waterways, which of the following is most likely to occur as a result?

B. The dissolved oxygen in the adjacent waterways would decrease because used coolant water is warm and leads to thermal pollution Correct. The temp. of the used coolant water is typically higher than the water temp. of adjacent waterways. When the used coolant water is released, it increase the temperature of the water in adjacent waterways. As water temp. increases, dissolved oxygen decreases.
