| Resumo: | The search for efficient methods to carry out water storage is a constant in regions such as the Brazilian semi-arid region, where there are low rainfall, high temperatures, high evapotranspiration and scarcity of perennial water sources; Given these circumstances, underground dams are widely used alternatives in these regions for water storage for human consumption, animal watering and agricultural irrigation. Therefore, the present work seeks to analyze the data obtained from three dams, in relation to the adequate standards for human consumption established by the Ministry of Health in Ordinance No. suitable for primary human consumption and which need treatment, and finally to suggest effective treatment methods at low cost, which promote the improvement of water quality, ensuring consumption. The samples were collected in three underground dams located in different municipalities in the semiarid region of Rio Grande do Norte (Paraú, Jucurutú and Serrinha dos Pintos) in two periods (rainy and dry), in order to verify the adjustment needs and propose viable solutions. for improving water quality. The study included the analysis of 18 parameters of a physical, chemical and microbiological nature of the water, where all the dams showed disapproval for primary human consumption, requiring the application of treatment methods to make this consumption safe. The water quality, according to the parameters evaluated, does not indicate a risk for secondary human consumption. |
