The Undersecretariat of Environment of the Municipality of Concordia has prepared a report on the recent fish mortality observed in the Yuquerí Chico Stream over the past weekend.
As a first point and following the report of the event, actions have been initiated to evaluate the possible causes and plan preventive measures to mitigate future environmental impacts on our watercourses.
Preliminarily, the possible causes of the fish mortality may include multiple events. Among these could be the significant reduction in the flow of the Uruguay River, which dropped approximately 1.5 meters in just 24 hours; high temperatures; as well as a high organic load that may have reduced the levels of dissolved oxygen in the watercourse. These combined factors could have created an unfavorable environment for aquatic fauna.
Given the current climatic conditions, which result in a dilution of the concentrations of substances in the water, no sampling was carried out this Monday since the results would not be representative. However, during the month of October, analyses were carried out in the Yuquerí Grande and Yuquerí Chico streams, as part of the control procedures carried out by the Undersecretariat of Environment.
In this line, an agreement is about to be signed with the Faculty of Food Sciences of the National University of Entre Ríos, to carry out a monitoring plan for the city's surface watercourses.
Regarding the discharge of industrial effluents, monitoring and inspection of industries are being carried out, requesting information on effluent outflow. In case of detecting violations of national, provincial, and municipal legislation, the corresponding sanctions will be applied.
The municipality defines the requirement for companies, requesting the performance during the course of this month of November 2024, of the analyses of effluents discharged into streams or rivers by an authorized, public, and trusted institution, such as the National University of Entre Ríos (UNER), and complying with the legal requirements established in Provincial Law No. 6260.
The Undersecretariat of Environment reaffirms its commitment to environmental protection and the preservation of natural resources.
