Inorganic, microbiological and organoleptic chemical characteristics of drinking water during the dry season in the urban area of the Pomahuaca district, Jaén province, 2019

Abstract

This investigation has been a starting point for solving the problem of poor drinking water quality in the district of Pomahuaca. In which his contribution to improving the performance of drinking water distribution systems in rural communities. The objective of the investigation was to identify the notable presence of total and thermotolerant coliforms, well above the LMPs. The study was of an experimental type from the quantitative approach and the descriptive method, using a 14 sample at different sampling points, in the which the technique of data collection materials and observation was applied, with an instrument the observation guide and analysis matrix. Obtaining the results in the sample the detection of total coliforms of the order of 1.6x103 NMP/100 mL, >200 and >200 CFU/100 mL at 35°C; at the three sampling points. 2.9x102±0.31 MPN/100 mL; 165.3±30.75 and 164±48.49 CFU/100 mL at 44.5 °C of thermotolerant coliforms. Both types of bacteria, well above the LMP set in the D.S. No. 031 – 2010 – SA. Turbidity values ​​of 8.58±1.22; 12.41±2.82 and 13.17±3.53 UNT; also, above 5 UNT, which is the allowed level. Conclusion it is determined to classify the water as unfit for human consumption. The other parameters reflected a soft and alkaline water. Favorable characteristics for the enjoyment of a healthy and comfortable life.
