Gulf Coast Network (GULN)

Water Quality Monitoring

Freshwater systems in GULN parks are sampled using methods developed by the U.S. Geological Survey National Water Quality Assessment (NAWQA) and the Texas Commission on Environmental Quality Clean Rivers Program (CRP). Existing sampling data is used whenever possible. The GULN coordinates with these agencies to ensure that data are consistent and comparable with similar information gathered throughout the region.

Coastal and estuarine systems are sampled using methods developed by the Environmental Protection Agency Environmental Monitoring & Assessment Program and the NPS Southeast Coast Network.
