Waterborne diseases were once wrongly explained by the miasma theory, the theory that bad air causes the spread of diseases. [ 27 ] [ 28 ] However, people started to find a correlation between water quality and waterborne diseases, which led to different water purification methods, such as sand filtering and chlorinating their drinking water.
The quality of drinking water is ensured through a framework of water safety plans that ensures the safe disposal of human waste so that drinking water supplies are not contaminated. Improving the water supply, sanitation, hygiene and management of our water resources could prevent ten percent of total global disease. [13]
MacKenzie et al. and the CDC showed that this outbreak was caused by Cryptosporidium oocysts that passed through the filtration system of one of the city's water-treatment plants, arising from a sewage treatment plant's outlet two miles upstream in Lake Michigan. This abnormal condition at the water purification plant lasted from March 23 ...
The usual cause of death is dehydration. Most cases of diarrheal illness and death occur in developing countries because of unsafe water, poor sanitation, and insufficient hygiene. Other waterborne diseases do not cause diarrhea; instead these diseases can cause malnutrition, skin infections, and organ damage. [3]

Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [1]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from ...
Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types: Water body stagnation (stagnation in swamp, lake, lagoon, river, etc.) Surface and ground water stagnation; Trapped water stagnation.
