Kilómetros de cambio

This Friday, we’re running with Kilómetros de Cambio!

The San Juan Bay Estuary Partnership is an ally of this relay race throughout the island, in benefit of women victims of violence.

Estuario’s Executive Director, Brenda Torres, will run on Stretch #7, from Quebradillas to Aguadilla (13.55 miles), on May 17, 2024.

Stretch #7 will be captained by Olympic triathlete, Melissa Rios.

We understand that the state of our environment reflects our quality of life and that, in order to achieve environmental justice, resilience, or access to clean water, it is necessary to eradicate violence from our communities. Learn more about Kilómetros de Cambio, here.

Oil & Grease Management Education Effort

On Thursday, May 9 and Friday, May 10, 2024, we visited around 50 businesses in Calle Loíza, in Santurce, to discuss and guide them on the correct handling and disposal of used cooking oils and grease.

In addition to the correct handling of oils and grease, we provided literature touching on the topics of inspection processes by regulatory agencies, legal bases, and the environmental benefits of executing good practices.

We thank the staff of the businesses we visited, and their positive reception to this effort!

This effort is possible thanks to the collaboration of the San Juan Bay Estuary Partnership with the Office of Environmental Compliance and Planning of the Municipality of San Juan and the Oil and Grease Control Program of the Aqueducts and Sewer Authority of Puerto Rico. It’s part of the community campaign, Que no toque el piso ni llegue al agua.

Educating Our Communities on Resource and Waste Management

Last Friday, May 10, four students began an education and awareness internship in resource and waste management with Estuario. Over the next 10 weeks, these youth will support the San Juan Bay Estuary Partnership’s education efforts related to the management of resources and waste in the basin, especially in the management of oils and grease. This effort will be coordinated with the Intermunicipal Network for the Integrated Management of Resources and Waste in the watershed. We hope this internship will be one of benefit and learning!

Water Quality Day in numbers

On Saturday, April 13, the sixteenth Water Quality Day of Puerto Rico was held.

Over 1,000 people participated from around 200 monitoring stations throughout the island. View the collected monitoring data on the event portal.

We thank the sponsors of the sixteenth Water Quality Day of Puerto Rico: Environmental Protection Agency Region 2, EarthEcho, Ford de Puerto Rico Environmental Donations, MAPFRE, and the Department of Natural and Environmental Resources of Puerto Rico.

We are also grateful for the collaboration of: Surfrider Rincón, the Community Water Network, Ponce Health Sciences University, the Inter-American University of Puerto Rico, Fajardo campus, the University of Puerto Rico, Río Piedras campus, EcoExploratorio of the Puerto Rico Science Museum, BoriCorps in Salinas, AmeriCorps, the Autonomous Municipality of San Juan, and the groups Homeschoolers from Guayanilla and Morovis.

Other activities

Coastal vegetation plantings:

On Saturday, April 27, 2024, we carried out a planting of coastal vegetation in Playita San Gerónimo of the Condado Lagoon, as part of the Coastal Resilience Module of Estuario’s Citizen Scientists Certification.

Sixteen citizen scientists planted some 187 specimens of various types of coastal vegetation, together with the coordinators, Agnes Pagán and Andreína Alexatos.

They also took time to discuss the importance of incorporating green infrastructure as a method to strengthen our coastlines.

Then, on Saturday, May 4th, 30 participants accompanied Andreína Alexatos in the planting of around 311 red, white and black mangrove specimens in Playa Jobos, Isabela. This planting was done in collaboration with Surfrider Foundation.
