Suppose some commercial interests want to develop a golf course on what is presently forested land next to a reservoir used for city water. Describe the impacts this development might have on water quality in the reservoir
What will be an ideal response?
The impact from a golf course could include contamination from nitrates and phosphates (fertilizers), pesticides, and sediments from erosion. Increased flow of sediments into the reservoir could influence the taste, color, and odor of the drinking water. The nitrates and phosphates could increase the growth of algae and other organisms, lowering the level of dissolved oxygen in the reservoir. Any fish or benthic organisms in the reservoir would be adversely impacted. The pesticides could include hormonally active agents or other compounds that are related to adverse human impacts.
