Study Evaluates Agricultural Best Management Practices in Puerto Rico to Minimize Negative Impacts to Coastal Watersheds
National Centers for Coastal Ocean Science researchers, working in collaboration with the Jobos Bay National Estuarine Research Reserve, recently completed a field mission designed to help determine the impacts of agricultural pollution on the Reserve with the goal of ultimately developing ways to reduce them. Scientists sampled 44 sites within Jobos Bay, including 14 sites in the Reserve, for sediment contaminants. Four sites in the Reserve were located at the existing National Estuarine Research Reserve System Wide Monitoring Program sites. These samples will be analyzed for a suite of contaminants including trace and heavy metals, selected pesticides, PCBs, PAHs, and PBDE (flame retardants). This field work is a component of a larger cooperative project with the United States Department of Agriculture, the Environmental Protection Agency, the United States Geological Survey, and Puerto Rico Department of Natural Resources to assess the effectiveness of agricultural best management practices in the watershed.
