Santee River Basin Study Flow-Path Study
Back to Santee groundwater main page.
The groundwater
flow-path study was designed to track the transport of nutrients and pesticides
from a corn field where they were applied, through the shallow flow system
that underlies the corn field, a field of planted pines, a hay field,
where additional nutrients and pesticides were applied, and the forested
floodplain/wetland, to areas of discharge in Cow Castle Creek near Bowman,
SC. A total of 28 multiport samplers were installed along a transect beginning
at the uphill edge of the corn field and ending in the middle of the creek.
Lithologic information was recorded and water samples were collected and
analyzed from each sampler and from the stream. Most samples were analyzed
for nutrients, pesticides, major ions, organic carbon, chlorofluorocarbons
(CFCs), and dissolved gases. On-site measurements of water levels, flow
directions, and field parameters also were made during each visit. (Click
