COMMUNITY ENGAGEMENT CORE SUMMARY/ABSTRACT The Community Engagement Core (CEC) will build bidirectional partnerships with target communities to enhance understanding of the health risks posed by emerging water contaminants in the environment (specifically 1,4- dioxane (1,4-DX)), and to provide interventional strategies that will improve public health and inform health policy. In the first phase of the project, the CEC will focus on communities in Nassau and Suffolk counties of Long Island, New York. These communities include residents whose public drinking water wells are impacted by nearby EPA Superfund sites. The CEC will work with the Research Translation Coordinator (in the Administrative Core) to develop replicable tools and resources to provide data and generate knowledge among stakeholders who are invested in addressing water-related issues in the State of New York, especially in areas near Superfund sites. To accomplish this, we will identify effective methods to communicate risk information to each stakeholder group, including the economically-disadvantaged and environmental justice communities proximal to these sites. The specter of emerging contaminants in drinking water is fraught with uncertainty about risk and appropriate courses of action, creating an atmosphere of confusion, blame, anxiety and, most importantly, mistrust. The CEC will address these challenges through facilitation of engagement and information exchange among the diverse and relevant constituencies in NY. We will create opportunities for constituent groups, including federal, state and local governmental agencies, to learn from each other and share information. We will encourage and facilitate multi-directional interactions among communities and experts to complement and support the Yale Superfund Research and Training Program’s (YSRTP’s) overarching objective of fostering research that improves the exposure assessment, health evaluations, and mitigation of emerging contaminants in drinking water in EPA Regions 1 (New England) and 2 (New York, New Jersey, Puerto Rico, US Virgin Islands and eight Tribal Nations) and North Carolina. In addition, we will collaborate with the Research Experience and Training Coordination Core (RETCC) to educate and train the next generation of scientists to conduct citizen science and develop skills for advocating for environmental justice and equity. The initiatives implemented in this proposal will be transferable to other communities facing similar challenges including the State of New Hampshire, which will be the second targeted area for CEC activities. We will also be sharing our findings and experience with the North Carolina State University Superfund Center, which is collaborating with the YSRTP’s research projects. The overarching goal of the CEC is to engage, educate and empower residents in impacted communities so they may understand and inform public health policy, and participate in the improvement of public health.
