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 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.
