Abstract

Water, a word with only four letters, but with unequaled importance for the survival of living beings. survival of living beings and knowing this worldwide importance, how can we define it? can we define it? Water can be defined in several ways, for COSTA et al, 2003; ASSIS et al., 2014. Water is one of the most abundant elements in nature and of great importance for the life of all living beings. For BONFANTE et al, 1999. Water is defined as the most abundant liquid on the planet and is essential for the survival of plants, animals and microorganisms. In the same line of reasoning BRUNI, 1993; says that water is one of the most present substances in nature and a vital vital and indispensable element for the survival and existence of all living beings in general. Thus, based on the definitions cited above, I can define that water is nothing more than a combination of water is nothing more than a combination between two atoms of the periodic table one of the most important and vital sources of life, and cannot be replaced by any other known liquid by any other liquid known, being well corroborated in the words of WHO, 2011; which states that water is essential to sustain life, and a satisfactory (adequate safe and affordable) supply must be accessible to all. Since in Brazil, the right to consume quality water has been established since the Federal Decree No. 79.367 of March 9, 1977 (FREITAS & FREITAS, 2005). However, in order for this offer of safe and accessible adequate drinking water to be made throughout the country, the Ministry of Health through the National National Agency for Sanitary Surveillance (ANVISA), has been editing ordinances to address the control and distribution of water in the country, the most recent is the MS Ordinance No. 2914 of December 12, 2011 December 2011, determining that the potability of water is the responsibility of the State and the nation State and the nation, with the former having to ensure the proper management of water resources water resources and the second, the conscious use of the resource. The guarantee of the safety and potability of water depends on the proper functioning of several steps in the supply process the supply process, from treatment to distribution; and, if the water supply is 15 any of them present failures, there may be contamination process (BRASIL, 2011). With this from the ordinance issued by the Ministry of Health in 2011, were fixed the maximum levels of impurities in water for human consumption, where drinking water must drinking water must be free of thermotolerant coliforms or Escherichia coli in 100 ml of sample and absence of bacteria of the total coliform group in 100 ml (BRAZIL, 2011). Because total coliforms are gram-negative bacilli, aerobic or facultative anaerobic facultative anaerobes, non-spore forming, able to develop in the presence of presence of bile salts or surfactants that ferment lactose producing acid production of acid, gas, and aldehyde at 35°C over a period of 24 to 48 hours, and activity of the enzyme ß-galactosidase (BRASIL, 2013a). key words: water, water contamination, importance of cleaning
