Potabilidade Da Água De Cacimbas: Estudo De Caso Em Um Distrito Da Cidade De Barro, Ceará

Abstract: Several factors can affect the water quality of cacimbas, which makes it necessary to monitor it for human consumption. In this sense, the present work sought to analyze a physical-chemical and microbiological quality of water from cacimbas in the rural area of the district of Iara, city of Barro, Ceará. The waters were collected directly from the tanks in sterile containers, then they were stored in thermal boxes with ice for conservation and transported for analysis in the laboratory. Physical-agglomerated a… Show more

“…Hardness ranged from 20.80 + 0.17 to 217.60 + 3.75 mg/L, and refers to the concentration of calcium and magnesium ions expressed as carbonates and, to a lesser extent, iron, manganese, strontium and aluminum in the water (Souza & Sousa, 2020). Hardness is related to the geological nature of the watershed, and in this study the waters come from a region with a predominance of basaltic rocks (Libânio, 2010), which may have influenced the results of moderate hardness (50-150 mg/L) in 53.85% (7/13) of the samples.…”

“…The total dissolved solids/water salinity ranged from 34.43 + 0.38 to 243.33 + 3.06 mg/L, and consist of a set of organic and inorganic substances. Its presence in water comes from erosive processes, organisms and organic remains, or the incorrect disposal of garbage and sewage (Souza & Sousa, 2020), among the samples, water from water sources/ springs presented the lowest values of total dissolved solids, and low hardness values.…”

“…O valor do pH não só influencia na dissipação das formas livres e ionizada de vários compostos químicos, como também contribui para um maior ou menor grau de grau de solubilidade das substâncias e de determinar o potencial de toxidade de diversos elementos (Cruz, 2018). Desta maneira, ressalta-se que a água com pH abaixo de 6,0 é classificada como ácida e corrosiva e acima de 9,5 como básica, contribuindo para precipitação de sais e incrustações dos mesmos, assim o pH é essencial para manter em boas condições as tubulações que conduzem a água as residências (Souza;Sousa, 2020). O valor do pH indicado para a proteção à vida se estabelece entre 6 e 9, reiterado pela Portaria de Consolidação do Ministério da Saúde, MS (2017) na qual recomendase que, no sistema de distribuição, o pH da água deva ser mantido na faixa de 6,0 a 9,5 (Cetesb, 2018).…”
