Physicochemical characterization of the water of the stream The Toma the city of Neiva Huila Colombia

Abstract

La Toma is a water source that crosses the urban area of ​​the municipality of Neiva in the department of Huila,it is affected by the urban growth that develops towards the eastern sector of the city, presents a regular distribution of solid waste and improvised connections of rainy waters. Therefore, the  water was physicochemically characterized, from which  pH, temperature, dissolved oxygen, conductivity, salinity, turbidity and iron concentration were determined on three monitoring stations located in the water source and analyzed with its meteorological variables, through a descriptive statistic and an analysis of variances (ANOVA). Subsequently, the results of the monitoring were compared with the current Colombian regulations. The physicochemical conditions presented by the water under study corresponded to pH values ​​7.44 ± 0.2429, temperature 23.91 ± 0.3447 ° C, conductivity 7.48 ± 0.8012 µs / cm, turbidity 28.71 ± 5.1730 NTU, STD 926.7 ± 74.78 mg / L, salinity 1.06 ± 0.0600 psu and iron 7.45 ± 2.8231 ppm; indicating, compliance with the regulations given by the parameters of pH, temperature and conductivity, and shows others outside the permissible limits such as turbidity, STD, salinity and iron concentration.
