Quality of Groundwater Distributed by Collective Alternative Solution in Rural Areas Interferes with Weather Variables

Theoretical benchmark: The seasonal and spatial variability of a spring can be monitored by physical, chemical and microbiological parameters, to ensure access to the population of drinking water, managed in a safe manner, since alternative and unsafe sources of water supply, and sometimes without treatment, pose risk to human health. Method: Quantitative, retrospective study of water samples collected monthly by monitoring the quality of water for human consumption in rural and urban areas from collective supply from January 2018 to December 2019. Results and conclusion: Precipitation interfered with all water quality indicators except free residual chlorine; and temperature interfered with turbidity, free residual chlorine, and fluoride. There was a correlation between fluoride and temperature; total coliforms and free residual chlorine, which suggests the possibility of antimicrobial action. Cross-sectoral actions to improve the quality of water supplied in rural areas are therefore proposed, through the adoption of continuous disinfection of all water sources. Research Implications: Presents important indicators on the quality of water consumed by the population, directly influencing the health of consumers. Originality/value: Research carried out in the rural area in Brazil is controversial about the interference of climatic factors in the quality of the distributed water. In view of the need to provide access to the population of drinking water, subject to safe and efficient treatments, without risks to human health, and for this purpose this study assesses the interference of climatic factors in the quality of water.
