Albemarle-Pamlico NAWQA

2001-2010 (Cycle II) Study Design

Albemarle-Pamlico Study (ALBE), National Water-Quality Study (NAWQA)

The Albemarle-Pamlico Drainage study, as part of the National Water-Quality Assessment, follows a nationally consistent study design. This national design allows comparisons among river basins and regionalization of results.

The goals of the NAWQA program are:

  1. Status: Assess the status of water quality,
  2. Trends: Assess trends in water quality,
  3. Understanding: Understand the factors that affect water quality.

The elements of the design of the 2001 (Cycle II) sampling and analysis program for the ALBE can, therefore, be categorized under these goals:




The four principal sites in the surface-water trend network are regularly sampled (approximately monthly) to evaluate seasonal and long-term trends and to characterize the types of chemicals found in the basins. Van Swamp at Hoke drains a forested swamp in the outer Coastal Plain and represents a minimally developed watershed. The Neuse River at Kinston, draining more than 2,700 square miles, integrates drainage from forested, agricultural, and urban lands. Contentnea Creek at Hookerton drains 740 square miles and is composed of more than 50-percent agricultural land. Swift Creek in near Apex, which drains 21 square miles, was selected to evaluate changes in a rapidly urbanizing basin; the population in Swift Creek increased about 62 percent between 1992 and 2000.
