Abstract
Understanding the chemical composition of a wetland sanctuary lakebed can help us understand how recent developments may have changed the chemical composition. Due to recent dredging by the U.S. Army Corps of Engineers and previous research on water composition at Heron Haven, the goal of this project was to determine the chemical composition as a function of sediment depth. The concentration of seven different metals and nutrients were analyzed in terms of depth. The aluminum, iron, and phosphate concentrations had no real discernible concentration change as a function of depth. There is some hint of a steady increase of manganese concentration as depth increases. Nitrate has an indiscernible concentration change as a function of depth. Nitrite and calcium have a very noticeable increase of concentration as depth decreased. These results can help us understand which metals and nutrients are precipitating onto the lakebed if not found in the lake water. This will help us understand why there is a difference of inflow/outflow metal and nutrient concentrations.
