Pathogens In Drinking Water

Water is the most important source for humans on earth. The ease of use of drinking water has been the most essential factor for continued existence throughout the development of all life. In the history of mankind, cultural centres were always founded in areas with a sufficient supply of freshwater. As the population amplified, the expected supply of water decreased, and all of the great cultures developed advanced techniques and systems to achieve access to new water reservoirs (e.g. drilling of wells and building of aqueducts) and to dispense water for consumption. Primarily, developing communities found that supplying and giving out of adequate volume of drinking water presented major problems (Szewzyk, Manz, and Schleifer). Before long …show more content…

The need of resource protection and drinking-water treatment became obvious when the relationship between bacteria in drinking water and the outbreak of various diseases was completed. The number of outbreaks that has been reported throughout the world demonstrates that the transmission of pathogens by drinking water is considered an important source of illness. The relationship between water contamination and the outbreak of disease resulted not only in the establishment of confined areas as sources for drinking-water production, but also in the decontamination of treated water to destroy or eradicate as many of the remaining bacteria as possible. Nowadays, in most developed countries, drinking water is taken as food, and high values are set for its quality and safety. The strict requirements for microbiological factors specify that bacterial content should be very low and that no pathogenic microorganisms should be detectable (Szewzyk, Manz, and Schleifer). These severe strains for the deficiency of pathogens, on the other hand, are consequential only for the classical pathogens like Vibrio cholera and Salmonella …show more content…

The achievement of these requirements demands resource protection and critical treatment of raw water, as well as precise quality control of the treatment process. Though, assessment of the behaviour of pathogens in drinking water is also crucial as a basis for additional improvements of the treatment process and for new regulations.
Water purification is the elimination of contaminants to produce water that is adequately safe for both human consumption and industrial use. There are however, various methods of purification as explained by Paul and Larry Goodyer:
