This project examined the impact of land use on chemical signature of trace and heavy elements (Cu, Pb, Zn and Ni) in stream sediments within Susquehanna estuary system, Otsego County, New York State. Eleven sediment samples were collected from Susquehanna drainage system and analyzed for acid and soluble extractables elements, and basic soil parameters such as organic matter, cation exchange capacity (CEC) and soluble salts. Results showed that concentration of elements are log normally distributed. Concentration of elements demonstrated spatial variability in stream sediments with a decreasing order of abundance: Zn>Pb>Cu>Ni Most of the element concentrations increase from upstream to downstream where there is a larger volume and possible longer contact time between the elements in solution and sediments. A positive correlation analysis among elements is suggestive of similar source. Further studies will focus on the concentrations of these elements in aquatic animals to determine possible impact on the ecosystem.
