Physical, chemical and microbiological parameters of water in rural settlement of amazonas: the case of PA Paciá (Lábrea /AM)

Abstract

Access to quality water in the rural area is a problem that requires government attention, since most communities do not have access to potable water. The quality of both surface and ground water intended for human consumption must meet quality and potability standards. In the present study, the objective was to evaluate the parameters of water consumed by the residents of the rural settlement PA Paciá, located in the municipality of Lábrea, in the southern region of the State of Amazonas, comparing the indicators with the potability standard established by Resolution 2914/11 of the Ministry of health. For this, collections were carried out in sixteen wells in the settlement and the physical (Turbidity, Color, Hardness and Alkalinity), chemical (pH, Iron, Manganese and Nitrate) and microbiological (total coliforms, thermotolerant coliforms and Escherichia coli) parameters were analyzed.). The settlement is divided into three lines and line 2 presented the worst water quality conditions, with changes in the levels of pH, iron, manganese, turbidity, color, total coliforms, thermotolerant coliforms and E. coli. It was concluded that the residents of the settlement are consuming improper water and are subject to health problems. Measures need to be taken to mitigate and prevent damage to the health of residents.
