Presentation Abstract
Coastal water quality in the Grand Strand of South Carolina is directly influenced by human activities. Nutrient-rich runoff, stemming from numerous anthropogenic sources, finds its way into coastal waters through freshwater inputs often through tidal creeks termed swashes. In order to better describe the amount of nutrient inputs into Singleton Swash and White Point Swash, we examine the various sources of anthropogenic runoff from isolated identifiable point discharges and their nutrient concentrations, as those compare to annual patterns where available. We report concentrations of dissolved inorganic nitrogen (DIN, as the sum of nitrate, nitrite and ammonium) and phosphate in discharge and creek water. We hypothesize that nutrient concentrations of isolated, minor point discharges are not significant enough to alter primary channel chemistry due to rapid flow rates, and suggest that non-point sources may play a larger role in nutrient loading in the coastal zone.
