Estuaries are aquatic resources that host many aquatic and terrestrial species, making them important ecosystems. However, their condition is threatened by contaminants that may be carried out by the rivers or from the sea. Water quality testing has been an excellent tool to monitor the health of the estuaries. However, it involves the use of different instruments and reagents, which makes these tests expensive ones. The characterization of macroinvertebrate communities in aquatic ecosystems has been used as a tool to monitor the biodiversity of these organisms, and it has been recommended as indicator of water quality. Therefore, in this research we evaluated if there is correlation between the presence or absence of microorganisms or changes in biodiversity, with water quality test results in the Natural Reserve Pantano Espinar and Caño Madre Vieja in Aguada-Aguadilla, Puerto Rico. Results showed that water parameters were within the established limits, confirming good water quality during our sampling period. Biodiversity indexes were compared, and results are summarized in this poster.
