Paraguay: Increases pollution of Lake Ypacaraí

The Multidisciplinary Center for Research in Technology (CMIT-spanish) contradicts the latest report from the Health Surveillance and alerts that this summer the lake should not be enabled, even for sports.

Rather than diminishing, is increasing pollution of Lake Ypacaraí, as corroborated CMIT experts based on a study on the presence of cyanobacteria in the famous pond.

Inocencia Peralta, director of the center under the National University of Asunción (UNA-spanish), revealed that the lake showed no improvement to be considered its qualification for this summer.

The famous water reservoir has lots of algae, which makes the lake can be enabled for sports, as local authorities say far from for recreational use.

Studies conducted by the institution in charge showed a high degree of contamination, even at 200,000 cells of cyanobacteria in some parts of the pond.

The reproduction of these algae is driven by the presence of nutrients in the water, the pH and high temperatures.

These results opposed to dangerously released by the Directorate of Health Surveillance, who suggested on 20 November, to cease the epidemiological alert and enable the lake ” for recreational purposes,” not for swimmers.

The recommendation was based on a report by the Directorate General of Environmental Health (Digesa -spanish) that on the last November 12 reported significant reduction in Raciborski Cylindrospermopsis and Microcystis aeruginasa over previous monitoring. , these bacterias were presented in well below 20.000cel/ml range set by the World Health Organization (WHO).
