Access reports, studies, and scientific publications about the San Juan Bay Estuary, its watershed, and its ecosystems. This collection brings together information on water quality, biodiversity, habitats, climate change, and other topics that support the understanding, management, and conservation of the estuary.
Historical document presenting the environmental status of the San Juan Bay Estuary at the time of the 2000 Management Plan, including information on water and sediment quality, habitats, biodiversity, pollution, hydrological modifications, and citizen participation.
This report presents a diagnosis of the main climate and environmental risks facing the San Juan Bay Estuary and proposes adaptation strategies to protect its ecosystems, infrastructure, and communities. It includes threats such as heavy rainfall, droughts, and rising temperatures and sea levels. The report is available in English.
The Fourth Environmental Condition Report of the San Juan Bay Estuary (2024) presents an updated view of the ecological state of the estuarine system, integrating scientific research, environmental monitoring and citizen science experiences to support decision-making and promote the resilience of the metropolitan region.
We have reviewed the socio-ecological, hydrological, and geochemical literature that is available for the ecological systems of the San Juan Bay Estuary (SBAS), a site in the Environmental Protection Agency's National Estuary Program.
The Estuary conducts water quality studies that include weekly monitoring of bacteria indicative of contamination from untreated sewage. This section presents data and studies conducted in the Condado Lagoon Estuarine Reserve, along beaches within the estuary watershed, and on wastewater discharges associated with the pump operated by the Department of Natural and Environmental Resources (DRNA) on De Diego Avenue.
We wish to share the scientific article entitled “Passive sampling of contaminants of emerging concern in a Caribbean urban estuary in Puerto Rico,” published in the peer-reviewed journal Marine Pollution Bulletin 213 (2025). The researchers of the study are Dr. Carlos J. Rodríguez Sierra and Dr. Imar Mansilla Rivera, professors in the Department of Environmental Health, School of Public Health, Medical Sciences Campus, and Dr. Jorge F. Bauzá-Ortega, scientific director of the Estuary.
The San Juan Bay Estuary (hereinafter, Estuary) was created as part of an effort to identify, recommend and implement a management plan with actions aimed at improving and protecting the natural integrity of the estuary and its uses.
This report contains the results and conclusions of a contamination assessment of sediments and biota conducted in the San Juan Bay Estuary (SJBE) under the Project entitled – Estuarine Environmental Indicators for the San Juan Bay Estuary: Assessment of Sediment and Fish Tissue Contaminants (the “Assessment” or “Study”).
You will start receiving our updates starting this Friday.
