Caracterización de calidad del agua de las vertientes Shushuri para uso agrícola del caserío Salate

Abstract

The present research work aimed to characterize the water quality of the Shushuri springs for agricultural use in the Salate village. The water samples were taken at three strategic points called M1, M2, and M3; from each issue, a liter of water was taken in sterile amber bottles and kept in refrigeration to later analyze the irrigation water quality parameters established by the sodium absorption ratio (RAS) and Annex 1 book VI of the Unified Text of Secondary Legislation of the Ministry of the Environment: Standard of Environmental Quality and Discharge of Effluents Water Resource (TULSMA). The parameters analyzed were pH, electrical conductivity (EC), total dissolved solids (TDS), temperature, bicarbonates, chlorides, sulfates, nitrates, boron, magnesium, sodium, cadmium, lead, chromium, mercury, fecal coliforms, and total coliforms, using laboratory techniques in December 2022, January 2023, and February 2023. For the statistical analysis, the completely randomized model (DCA), ANOVA, and Tukey were used, resulting in significant differences between the three-month averages in nitrates, magnesium, sodium, cadmium, and lead parameters. In addition, each parameter compares with the permissible limits established in the TULSMA. Concluding based on the RAS methodology, the water of the Shushuri springs is without restriction of use in December and February; on the other hand, in January, they present a light-moderate limitation; in addition, the parameters of total and fecal coliforms exceed the permissible limits established by the TULSMA giving a very high concentration. It recommends socializing the present work with the inhabitants of the Salate hamlet to inform them about the quality of the water they use for crop irrigation.
