The Albemarle-Pamlico Drainage Study Unit (ALBE)
National Water-Quality Assessment (NAWQA)
The
National Water-Quality Assessment is an
ongoing program of the U.S. Geological Survey
to assess the status of the Nation's streams
and ground-water quality, assess trends
in water quality, and examine the processes
that control water quality.
Assessment
of the Albemarle-Pamlico
study area (ALBE) began in 1991 with
an intense 3-year period of surface-water,
ground-water, and ecological data collection
(Cycle
I). Data collection from 1993 to 2001
included ground-water flow path sampling
and monthly surface-water sampling at two
sites selected for long-term trend evaluation.
Intensive sampling began again in 2002 (Cycle
II), with a focus on evaluating the
effects of urban development on ecology
and water quality (Effects of Urbanization on Stream Ecosystems (EUSE)), nutrient
source and delivery modeling (Spatially
Referenced Regressions on Watershed Attributes
(SPARROW) modeling), and studying water
quality of the Castle Hayne aquifer.
