Abstract

This work had the objective of studying the physical-chemical quality of the water of an artesian well located in the urban area of the city of Remígio-PB. The water sample was collected in a 2 liter plastic bottle in an artesian well located in the urban area of the city of Remígio / PB and was sent to the Chemistry laboratory of the Federal Institute of Paraíba, campus of Campina Grande, to carry out the analyzes. All analyzes were performed in triplicate. The physico-chemical parameters of the water were determined following the methodologies of the Adolfo Lutz Institute manual. The parameters analyzed were: pH, temperature, apparent color, alkalinity, electrical conductivity, total dissolved solids, percentage of ash, chloride, turbidity, total hardness, calcium and magnesium hardness, total chlorine and percentage of iron. The sample had a mean pH value of 6.52 at a temperature of 26.3 °C, an average value of 368 uH for apparent color, 106.7 uT for turbidity, 42.67 mg/L CaCO3 for alkalinity and 104, 5 mg / L for chloride. In relation to total hardness, the mean value found was 92.67 mg/L CaCO3, 911.1 μS/cm for electrical conductivity, 5,957 mg/L for total dissolved solids, 0.0165% ash, 0.24 and 0.94 mg / L for total chlorine and iron, respectively. Therefore, it is concluded that water is unfit for human consumption, since the parameters apparent color, turbidity, total dissolved solids and iron percentage are totally out of the one recommended by the Consolidation Ordinance no. 05/2017 of the Ministry of Health and Resolution No. 357/2005 of the National Environmental Council.
