Other activities

Planting of coastal vegetation in Loíza

Last Saturday, February 17, 52 volunteers planted around 253 specimens of coastal vegetation throughout the Piñones beach in Loíza. In addition to planting, they held a short discussion about coastal reforestation as a method of sand dune restoration and conducted water quality monitoring in the area.

We thank all the volunteers who participated, and the green infrastructure and student participation coordinators, Andreína Alexatos and Agnes Pagán, who led the event. Until next time!

Classification of microplastics in the Torrecilla and Los Corozos lagoons

As part of the microplastic characterization and reduction module of Estuario’s certification for citizen scientists, several volunteers accumulated and identified samples of microplastics taken in a boat trip through the Torrecilla and Los Corozos lagoons.

Thanks to citizen scientist Roberto Muñoz, Estuario’s new Education and Citizen Science Manager, Sahid Rosado, and Captain Freddy Bracero, who accompanied our Aquatic Debris Manager, Cristina Ramírez, on this field trip.

Evaluation of runoff in Loíza Street

On Monday, February 26, our Aquatic Debris Manager, Cristina Ramirez, collected water samples from the storm sewer system in Loíza Street, following a rain event. Samples were taken on the Tito Matos, Las Palomas, Pomarrosa and Kings Court streets. These assessments are part of the efforts of the community campaign Que no toque el piso ni llegue al agua, an effort to reduce and responsibly manage solid waste and cooking oils in the community.
