Levantamiento de información del sistema de abastecimiento de la junta administradora de agua potable de Tolontag - Marco : calidad de agua.

Abstract

The evaluation carried out on the drinking water treatment system in the community of Tolontag is described, with the objective of identifying areas for improvement and guaranteeing water quality. A sampling plan was carried out at five specific points: collection tank, entrance and exit of the treatment plant and the two homes furthest from the plant. In situ (pH, conductivity, temperature, dissolved oxygen and turbidity) and laboratory parameters (arsenic, alkalinity, COD, BOD5, total hardness, total iron, manganese, phosphates, nitrates, total and dissolved solids, sulfates, chlorine) were analyzed. . . free of residual and total coliforms, total and fecal). The analyzes carried out on the community's raw water indicate that it is of excellent quality. For this reason, current treatment is limited to disinfection. However, the tests revealed that the disinfection process is not effective, since the concentrations of total and free residual chlorine are lower than the values ​​established by regulations. To guarantee the quality of water for human consumption, improvements are proposed to the current treatment, which is based on a constant drip hypochlorinator. These improvements focus on: Modifying the amount of disinfectant to prepare an adequate stock solution, recalculating the drip flow to ensure accurate and constant dosing, extending the contact time of the disinfectant with water for effective disinfection. These measures will ensure that community residents have access to safe, quality drinking water.
