Human intervention also has significant effects on water quality. The effects of water pollution can be catastrophic, depending on the kind of chemicals, concentrations of the pollutants, and where there are polluted. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. One of the purposes this cover provided was the protection of the soil. Awareness of the environmental conditions and human activities that influence water quality is an important part of effective water … Students will learn about the effects of human activities on water quality and water resources. Human is the only living being on the earth that is responsible for the destruction of the environment.He does it due to his ability to exploit the natural resources beyond the limits of safety. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The range in human activities that affect the interaction of ground water and surface water is broad. These changes may be caused by either natural factors or human activities. Secondly, we can also generate some guiding questions to break down the task into smaller parts. 1991 to assess the quality of the Nation™s water quality, to study how water quality changes with time, and to study how human activities and natural factors affect water quality (Gilliom, Alley, and Gurtz, 1995). 4).
