Water Pollution Concepts and Impacts

The video tutorial, prepared by John B and Sam Dr, supported by the National Science Foundation, covers water pollution, its types, and testing protocols. It discusses the historical pollution of the Kyoga River, leading to the establishment of the EPA and the Clean Water Act. The video explains point and non-point source pollution, various contaminants, and their sources. It details water quality parameters like temperature, pH, and dissolved oxygen, and their significance. The tutorial concludes with calculating a water quality index and engaging in hands-on activities and a virtual game.

• The concentration of heavy metals

• The amount of dissolved oxygen

• The level of organic pollutants

What can total suspended solids indicate in a water sample?

• The presence of pathogens

• The level of dissolved oxygen

• Areas of erosion

• The pH balance
