Dissolved oxygen is one of the most important parameters in aquatic systems. This gas is an absolute requirement for the metabolism of aerobic organisms and also influences inorganic chemical reactions. Therefore, knowledge of the solubility and dynamics of oxygen distribution is essential to interpreting both biological and chemical processes within water bodies. Oxygen gets into water by diffusion from the surrounding air, by aeration rapid movement and as a waste product of photosynthesis. The amount of dissolved oxygen gas is highly dependent on temperature.
Atmospheric pressure also has an effect on dissolved oxygen.

Many waterborne illnesses are due to less familiar bacteria such as species of Yersinia and Campylobacter, and toxins-producing strains of Escherichia Coli. An emerging pathogen associated with contaminated water is Vibrio vulnificus, a gram negative bacterium that can cause serious illness in persons with pre-existing liver disease or compromised immune systems.
Viral diseases transmitted by water include hepatitis A, gastroenteritis due to Coxsackie or Norwalk virus, and in rare instances, polio. These diseases are generally related to fecal contamination of water. Many protozoa form cysts that survive for long periods in water. Human Activities. Pollution caused by household garbage, the diminishing margin of safety between septic tanks and deep wells and pipes for potable water cause contamination to groundwater and exposed everyone to water-borne diseases.
Nearly everybody in the world lives in a river basin and everybody have contribution to make to prevent further damage to the environment. The threats facing river basins are varied and interlinked and require holistic policies rather than efforts that target just one aspect but can end up being counter productive.
