Análisis de la relación entre la tasa retributiva por vertimientos puntuales al agua con los objetivos de calidad establecidos por las autoridades ambientales CORANTIOQUIA y CAR Cundinamarca para el periodo 2017-2022

Abstract

This work analyzes the relationship between the Remuneration Rate for Timely Discharges into Water (TRVP) and compliance with the water quality objectives established by the environmental authorities of the Regional Autonomous Corporation of the Center of Antioquia (CORANTIOQUIA) and the Regional Autonomous Corporation of Cundinamarca ( CAR) during the period 2017-2022. To address this relationship, a quantitative methodology structured in several phases was used. Firstly, the key variables to be considered within the study were defined, subsequently, the validation of data obtained from the implementation reports of the Remunerative Rate for Specific Discharges into Water was carried out, analyzing both the billing of the rate and the contribution of different economic sectors and the behavior of the number of users during the period under study, allowing the identification of trends towards the reduction of pollutant discharged loads of BOD5 and TSS in both authorities, however challenges persist in meeting the global pollutant load goals. To delve deeper into this study, a Spearman correlation analysis was carried out, which quantified the relationship between the billing of the Remuneration Rate for Specific Water Discharges and compliance with quality objectives, indicating a negative correlation in both. jurisdictions. Furthermore, it was observed that the relationship between the billing of the Remuneration Rate for Specific Discharges into Water and the fulfillment of the polluting load goals varied significantly between the different hydrographic subzones, which shows that the TRVP can have diverse behaviors depending on the specific characteristics of each area.
