Manipueira, uma possível fonte de contaminação da água das cacimbas próximas às casas de farinhas no Engenho Benfica na zona rural de Barreiros

Abstract

In this work, analyzes of the water of the wells near the flour houses of the Benfica mill located in the rural area of the municipalities of Barreiros were carried out, where aiming to analyze the water of these wells to obtain necessary information to raise awareness. In that location, cassava residues, such as cassava, are improperly disposed of in the environment. With water in scarcity and possible levels of pollution, it is necessary to analyze the water to raise awareness in that region. The only source of water is through the artisanal waterholes that are close to the wand houses in that locality. The flour mills produce approximately 2,500 liters of cassava per month, which in turn is improperly disposed of very close to the artesian wells. Manipueira is a liquid extracted from cassava which is yellow in color when pressed during the flour manufacturing process. high concentration of hydrocyanic acid HCN found in manipueira, and the decomposition of the same since it is seen that it is discarded without control near water sources. In the first stage, water samples were collected from the three cacimba of the Benfica mill. This collection was carried out in three wells, all close to the flour houses. In the analysis, parameters such as: pH, chlorides, total coliform, thermotolerant coliforms and heterotrophic bacteria were evaluated. The classification of water potability was based on the parameters of the Ministry of Health Ordinance number 888 of December 4, 2021, which deals with the potability parameters of water for human consumption
