As part of this effort, ORD has developed a coastal monitoring program with EPA Region 6, and the Louisiana Department of Wildlife and Fisheries (LDWF). This program integrates elements of existing Louisiana estuarine and coastal monitoring and assessment efforts. This joint effort will determine the condition of estuarine waters in Louisiana and permit comparison to other U.S. coastal areas. The effort is being coordinated by the ORD National Health and Environmental Effects Research Laboratory's Gulf Ecology Division in Gulf Breeze, Florida. 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 2001 survey and the number of sampling sites in estuarine waters of Louisiana.
