Item Acesso aberto (Open Access) Ações de educação ambiental na sensibilização da qualidade da água para consumo humano no assentamento Palmares, no município de Araguatins, Tocantins(Universidade Federal do Pará, 2018-05-22) LIMA, Lílian Natália Ferreira de; SILVA, Cleber Silva e; http://lattes.cnpq.br/7673237583688618The importance of assessing the quality of water for human consumption is based on the fact that it is one of the main vehicles of infectious diseases. The objective of this research was to evaluate the quality of the water for human consumption, by means of the physical, chemical and microbiological characterization of the water of open and closed wells of the settlement Palmares, Araguatins (TO) and to develop an educational campaign based on the results obtained in the study, based on environmental education. The physical, chemical and microbiological parameters were collected during the period from October 16 to 20 in two wells of the settlement, using the multiparameter probe, turbidimeter, Ph meter, thermometer. The results obtained were compared with the resolution of the Ministry of Health nº 2.914 of 12/12/2011. The analyzed data of the wells of the settlement Palmares indicate that there is change in the behavior of some parameters. These changes were observed in the values of salinity (NaCl) that presented concentrations above the maximum concentrations allowed by Ministerial Order Nº 2.914 of 12/12/2011, the analysis of variance did not recognize the existence of significant differences between the collections of the mean values of the campaigns sampled from all groundwater parameters of the open and closed wells studied, indicating that there were no methodological errors, accepting the null hypothesis. According to Ordinance Nº 2.914/11/MS, results obtained in this study were unfit for human consumption, since the values of salinity, pH and E coli did not meet the potability standards, indicating contamination by organic matter. Still, it is concluded that the families of the palm groves are consuming water outside the potability standards stipulated by the Brazilian legislation and that the improvement of the quality of the water offered goes through the diffusion of sanitation technologies and the use of efficient methodologies for environmental education of the inhabitants of the settlements.
