Citizen scientists get certified in coastal resilience module

On Saturday, October 15, 2022, a group of estuarine citizen scientists completed workshops on coastal tropical ecosystems and sand dune restoration, placed wooden stakes for sand retention, and seeded coastal vegetation for sand stabilization. They also carried out microplastic identification and water quality monitoring activities. This event was carried out in collaboration with Vida Marina of the UPR in Aguadilla. The participants received their certification as citizen scientists in the coastal resilience thematic module.

Weekly water quality monitoring

Evaluation conducted Thursday, October 20, 2022.  We have a green flag for the Condado Lagoon Natural Estuarine Reserve. Even though some stations in Lagoon did not meet the standard, their bacteriological counts were not too high. The beach in front of Nairn Street was the only one throughout the coast that did not meet the water quality standard.We recommend avoiding direct contact with the areas that did not exceed the standards and being attentive to precipitation events.

Take advantage of our informative platform, the Virtual Community Hub, where you will find vital information to prepare your family and community.
