Showroom The estuary is not still

Focusing on water and the communities surrounding the San Juan Bay estuary, the 2026 Estuary Resident Artists exhibition, Antonio Martorell and Friends: The Estuary is not still, offers us a special, multidisciplinary perspective deeply linked to our coexistence with the bodies of water in the Estuary's watershed.

Through various artistic expressions, the collective exhibition invites us to reflect on our relationship with water, the communities that live and develop around it, and the importance of restoring, protecting, and conserving this vital resource.

There are only a few days left to visit! The exhibition will be on display at the Taller Comunidad La Goyco gallery until August 27, 2026. You can visit it Monday through Friday, from 8:00 am to 8:00 pm, and on Saturdays, from 9:00 am to 6:00 pm.

Learn more about the exhibition and read the review written by its curator, Rebeca Noriega, here: https://estuario.org/el-estuario-no-esta-quieto/

Help us document restoration and conservation efforts in the estuary watershed

Each year, we document habitat restoration and conservation efforts implemented within the San Juan Bay estuary watershed. In doing so, we gather valuable information to support public investment in the region.

We urge all communities, organizations, or agencies that carry out restoration and conservation projects in the region to submit their projects corresponding to the period from October 1, 2025 to September 30, 2026, including pending projects.

These projects are reported to the EPA and Congress. The form must be completed by September 30, 2026. We thank all the entities that are part of this effort. Access the form: HERE.

Job opportunity

Opportunities for professional services contracts

Reflection by Víctor Bonmatí, intern at the Estuary in 2026

My name is Víctor Bonmatí and I am an International Relations student at the University of Navarra. My professional aspirations are to work for a multinational NGO that operates in diverse areas of international affairs and public policy, where I can analyze complex problems, work with different sectors, and contribute to decision-making.

My work at the Estuary involved synthesizing and analyzing the scientific document "Economic Valuation Study" so that this information could be used to communicate with a wider audience. This document demonstrates the economic value and benefits that nature provides in the metropolitan area through ecosystem services, which the Estuary works to maintain. The document is vital for demonstrating the Estuary's importance to communities and for incorporating it into budgets, infrastructure decisions, zoning, and land-use planning.

I also reviewed the comments from communities in the metropolitan area on the CCMP (Comprehensive Estuary Management and Conservation Plan Review). These comments are essential for the Estuary and the various communities to reach an agreement, as the CCMP is the master document that guides our work as an organization and as a partnership.

Besides working in the office, I also had the opportunity to work in the field, taking water samples from Laguna del Condado for bacteriological analysis, and going to Laguna Torrecilla in a motorboat to conduct a microplastic characterization and reduction study. These field experiences make the work more dynamic and give you a perspective on the importance of what you do in the office, allowing you to see the results firsthand.

What surprised me most about my stay were the findings of the “Economic Valuation Study.” The economic value of the estuary is much higher than I expected, as is the wide range of ecosystem services it impacts. This highlights the importance of the estuary to Puerto Rico, not only in a moral sense (wanting to care for and maintain the environment), but also in a monetary sense.

This experience in the estuary has shown me the environmental importance of protecting ecosystems like mangroves, wetlands, and reefs, but I was unaware of the magnitude of their economic impact. It helped me strengthen my ability to analyze technical documents, identify relevant information, and communicate it in a simple and understandable way. It also allowed me to better understand how the environment, the economy, and public policy decisions are related. This is relevant to my studies, as it helps me better understand how organizations that seek to generate a public impact operate and how they make decisions with limited resources.

Actions for the reduction of aquatic waste

In the watershed of the San Juan Bay estuary

Pop-up Recycling in Loíza

Last Saturday, August 15, 2026, Estuario participated in the Recycling Pop-Up in Loíza, with an educational booth focused on raising awareness about vegetable oil diversion initiatives and the importance of protecting and conserving water quality. This event is held every third Saturday of the month at Miguel Fuentes Pinet Park. They accept #1, #2, and #5 plastics, aluminum, brass, and corrugated cardboard.

Microplastics study

On Friday, August 14, 2026, we conducted the monthly field experience for the Microplastic Characterization and Reduction module of the Estuary Citizen Scientist Certification. We thank the volunteers who joined us in collecting and identifying microplastics throughout Torrecilla Lagoon, enhancing their understanding of the science and applying what they learned directly in the field. We also thank Captain David of Kap Inc. for his support during this experience. 

Sign up for the next Microplastics Characterization and Reduction workshop. See more information below.

Don't panic! Get ready.

Weekly bacteriological monitoring

Assessment conducted on Thursday, August 20, 2026. We have a GREEN flag for County Lagoon. However, we recommend avoiding areas that exceeded the "Beach Action Value" water quality parameter for enterococci of 70 CFU/100 mL. Remember to avoid the water during rain events. Have a good weekend.

Thanks for subscribing!

You will start receiving our updates starting this Friday.
