Determinación de la calidad del agua en los sitios de recreación turística: diques de Mera, Shell y Pambay de la provincia de Pastaza.

Abstract

The current research Project aims to determine water quality in recreational tourist areas in the Mera, Shell and Pambay docks of Pastaza province, the study was based on several biological indicators. Two macroinvertebrate inventories were carried out in three sites: encountering 26 families, 603 individuals in wintertime and 604 in summertime, standing out the Leptophlebiidae family in the two samples, this family belongs to the trophic collectors group as an indicator species of crystalline shallow waters, Subsequently was performed the indicators data analysis as well as physical-chemical of water. A total of 9 water samples were sent for further investigation in the ESPOCH CESTTA laboratory of the three wintertime dykes where 8 parameters were analyzed. In the statistical report of the Alpha and Beta diversity indices: being Alpha (Margalef, Pielou´s equity, Shannon´s equity and Simpson´s dominance) and in Beta (Sorensen and Bray Curtis) resultingin a low to medium diversity using the standard statistical method called ANOVA, in connection with the biological indices, which resulted in less than 0,5 the significant value levels. This shows that touristic activity on the dykes is negatively affected by the water quality along with the biological indices; BMWP, ABI, IBMWP, and IA, through this full process was determined the contamination degree present in the tourist resort areas, being highly contaminated poor qualily waters.

Key words: WATER QUALITY - MACROINVERTEBRATE INVENTORIES - RECREATIONAL TOURISM.
