The San Juan Bay Estuary Partnership, also known as Estuario, is requesting proposals from experienced organizations/firms with a proven and successful track record to conduct an Environmental Health Impact Assessment (HIA) as the Estuario’s Public Health Service Provider. The HIA will analyze the association between illicit discharges in the San Juan Bay Estuary Watershed and public health in the community.

A scope of work is included to assist interested organizations/firms in the preparation of a proposal for conducting the HIA. The applicant should not be limited by this general scope of work but must address all of the solutions and work products called for in thisRequest for Proposal (RFP). Failure to submit information in accordance with the requirements and procedures established in this document may be cause for disqualification.


The Corporation for the Conservation of the San Juan Bay Estuary is a 501(c)3 non-profit organization that operates the San JuanBay Estuary Partnership, or Estuario. Established in 1994, Estuario is the only tropical and non-continental location within the National Estuary Program (NEP) under Section 320 of the Clean Water Act. The Estuario’s mission is to restore and conserve the waters and associated ecosystems of the San Juan Bay Estuary as a sustainable axis of social and economic development. As a National Estuary Program, Estuario’s focuses on implementing the Comprehensive Conservation and Management Plan (CCMP) for the San Juan Bay Estuary.


Since 2016, Estuario has conducted an Illicit Discharge Monitoring and Corrective effort that has successfully identified and corrected critical pollution areas due to the presence of sewage discharges. The Estuario looks to further that project by evaluating public health issues in these areas in order to understand the correlation between water quality monitoring data and the population’s health.Carrying out an HIA will help Estuario evaluate the potential health benefits of investing in resilient water infrastructure.


The San Juan Bay Estuary watershed or drainage basin extends above a broad, flat coastal plain and consists of 83 square miles (215 km2) of land and 14 square miles (36 km2) of water. The San Juan Bay Estuary ecosystem is compromised by the San Juan Bay and a number of smaller channels and lagoons. Some of these bodies of water include the San Antonio Canal, Condado Lagoon, San Jose Lagoon, Los Corozos Lagoon, Las Cucharillas Marshland, Torrecilla Lagoon, and the Piñones Lagoon as well as the interconnecting Martin Peña, San Antonio and the Suarez canals (See Figure 1). Fresh water flows into the system from the creeks and rivers in the watershed, including the Puerto Nuevo River, Juan Mendez Creek, San Anton Creek, Blasina Creek, and the Malaria Canal. During extreme flood events, freshwater is also received from the Rio Grande de Loiza.

Part of eight municipalities join to form the estuary’s watershed: Bayamón, Carolina, Cataño, Guaynabo, Loíza, San Juan, Toa Bajaand Trujillo Alto. Land use decisions and associated activities in these areas are closely linked to water quality impacts and the degradation of habitat in the estuary. The San Juan Bay estuary watershed houses many of the municipalities with the highestpopulation density and the most heavily urbanized areas related to the metropolitan area of Puerto Rico. Over 70% of its territorial extension is developed and paved over, which represents a constant stressor to this impacted, yet diverse and valuable estuarine ecosystem.

The Service Provider will design and perform a Health Impact Assessment (HIA) within locations that have been previously identifiedas critical pollution areas due to the presence of sewage discharges. The locations are based on the diagnostic points identified by our Illicit Discharge Detection and Elimination team due to significant presence of illicit sewage discharges. This assessment should evaluate the potential association between common illnesses experienced such as gastrointestinal, neurological, respiratory, atopicdermatitis conditions by the inhabitants of the area and the rural or urban environment they are exposed to. The Service Provider should integrate the findings from a Risk Assessment and Stakeholder analysis that the Estuario will carry out to understand this correlation to the population’s health. The results of HIA will be made public to the Estuario and its partners/key stakeholders suchthat it that will help guide actions to implement certain environmental justice programs such as wastewater infrastructure improvement projects. This will be an essential tool for Estuario to inform public policy decisions made by elected officials, municipalities and agencies representatives.


  1. Develop a strategy to assess the association of common illnesses experienced by the inhabitants of the area and the critical pollution diagnostic points they are exposed to, caused by raw sewage in the rural or urban environment withinthe San Juan Bay Estuary
  2. Develop a data collection method to evaluate and analyze the association between population health within the critical pollution diagnostic points and the exposure to raw sewage using a multivariate method approach.
  3. Conduct and present a Health Impact Assessment that will analyze health
  4. Propose mitigation strategies to reduce the impact of raw sewage discharges on population health and reduce the knowledge gap among the population.
