DETERMINACIÓN FISICOQUÍMICA Y MICROBIOLÓGICA EN AGUA DE RIEGO EN SAN JOAQUÍN-CUENCA, 2023.

Abstract

Introduction: The quality of irrigation water in San Joaquín-Cuenca contains several contaminants, so it is essential to know them to avoid public health problems. Objective: To determine the water quality at the water intake point of the "Toma de Narváez" irrigation canal, San Joaquín, through physical-chemical and microbiological methods. Methodology: A non-experimental quantitative study was carried out. The sample consisted of 30 samples collected during a month from the Tomebamba River in the area of Balzay Alto in the parish of San Joaquín during the year 2023. The data collected were processed in SPSS version 26, and descriptive and inferential statistics were used to analyze the information through the use of tables and charts. Results: The mean of the studied parameters of the 30 samples was analyzed, where the total dissolved solids (TDS) showed a mean of 62.45 mg/L, electrical conductivity (EC) of 0.087317 mho/cm, nitrites of 0.017 mg/L, pH of 6.89, fecal coliforms (E. coli) of 282.97 NMP/100Ml and the absence of parasite eggs. Conclusion: The physicochemical and microbiological parameters studied are within the values established in the environmental quality and effluent discharge standards established in Annex 1 of Book VI of the Unified Text of Secondary Legislation of the Ministry of the Environment of Ecuador.
