United States Environmental Protection Agency Office of Research and Development Washington DC 20460 EPA/620/R-01/001n February, 2002 >&EPA Coastal Communications ft National Coastal Assessment: Delaware ORD/Region 3/OW/DNREC n o , 2OOoJ Delaware NCA Design (2001) PA Background The U.S. EPA's National Coastal Assessment (NCA)is a multi-year partnership among EPA's Office of Research and Development (ORD), EPA's Office of Water (OW), EPA's Regional Offices, all coastal states, and selected territories. As part of this effort, ORD has developed a coastal monitoring program with the state of Delaware, EPA Region 3, and the Delaware Department of Natural Resources and Environmental Control (DNREC). This joint effort will determine the condition of estuarine and inland bay waters in Delaware, and permit comparison to other U.S. coastal areas. This effort is being coordinated by the ORD National Health and Environmental Effects Research Laboratory's Atlantic Ecology Division in Narragansett, Rhode Island. National Coastal Assessment Strategy The National Coastal Assessment is a strategic partnership between EPA and the coastal states and other federal agencies. Each state uses a compatible probabilistic design and a common set of environmental indicators (see Table below) to survey its coastal resources and assess their condition. These estimates can then be aggregated to assess conditions at the EPA Regional, biogeographical, and national levels. All data will be made available for public access on the Internet. The map shows the coastal areas included in the survey and the number of sampling sites intended for the estuarine and inland bay waters of Delaware. Selected sampling sites from the existing Delaware Bay Monitoring Program were incorporated into this NCA survey.
