Análise da qualidade da água distribuída no município de Sorriso-MT

Abstract

Water is present in all life forms in our planet, so it is the most precious commodity to the live existence, once the survival of all species on the planet depends on it. However, due to all anthropogenic and natural contamination, the human need to be very careful with the water self consume. To the water keep the human body healthy, it must present a minimum potability, and this is the principle of water treatment processes and wastewater. The Ordinance 2.914/2011 of Health Ministry describes about the control procedures and monitoring of water quality for human consumption and its potability standards. The water to human consumption can be captured from surface water and groundwater sources, depending on which source it present better quality and ease of operation and maintenance for the benefiting community. In the Sorriso-MT city, all water intended for human consumption are captured from groundwater sources, which present better quality, ease maintaining distribution and treatment system, once it does not require a complete treatment plant, reducing the treatment processes and the use of chemicals agents. To analyze the potability of the water distributed in Sorriso-MT, it was carried out and analyzed its physical-chemical and bacteriological parameters from Jan/2014 until Dec/2015. Based on data from the two years, the results were confronted with the Ordinance 2.914/2011 of Health Ministry to confirm if the potability standard required are found. Most of the parameters analyzed, like total coliforms, Escherichia coli, turbidity, color and disinfection are in accordance with the Ordinance 2.914/2011, however, the pH presented majority acidity, but it parameter does not implies risk to final consumer.
