Validación de datos de turbidez obtenidos con el método del Disco Secchi en comparación con el método del turbidímetro en las aguas de la laguna Kulta Kucha, del cantón Colta, provincia de Chimborazo durante el periodo abril-agosto del 2016.

Abstract

The objective of the research was to validate turbidity data obtained with the method of the Secchi disk in comparison with the method of turbidimeter in the waters of the lagoon of Kulta Kucha of the canton Colta. There was a correlation between the values of turbidity vs. Luminous penetration on three specific sites: in the surroundings of the lagoon, in the middle of the lagoon and next to the cattails to determine the turbidity of the same through the use of the Secchi disk and the turbidimeter since it is assumed that the turbidity depends mainly on the characteristics of the place where samples are taken. The results were gathered in inventories later to realize the statistical analysis in the program IBM SPSS statistics where Studen T-test was applied for independent samples giving like result that its averages are similar therefore the variances between the Secchi disk and the turbidimeter are equal; sufficient evidence that allowed concluding that the data of turbidity are equal using disk Secchi or the turbidimeter. Additionally by this research was able to obtain the turbidity values of the three sites in study being its outcome in the surroundings of the lagoon an average of turbidity of 3,1597NTU, in the centre of the lagoon average turbidity is 0,6010NTU, and finally the average turbidity of the water next to the cattails is 14,7731NTU. It was concluded that the site of the lagoon Kulta Kucha with greater turbidity is next to the cattails, assuming that it is mainly to the presence of algae that exist. The use of disk Secchi is recommended as instrument to determine the turbidity of the water in the lakes to be cheaper since the results indicate that there is no difference when using Secchi disk or the turbidimeter.
