Phosphorus plays a key role in the occurrence of eutrophication and toxic algal blooms in aquatic environments. Past research has shown that land use and lithology are major contributors of phosphorus in a creek. High levels of organic phosphorus occur in agricultural areas of a watershed, and high levels of inorganic phosphorus occur in residential areas, especially near waste water treatment plants. Limestone bedrock results in high levels of calcium associated phosphorus. Northrup Creek, a mixed land use watershed in western Monroe County, New York, was examined to determine the main contributors of phosphorus in the creek. Fluvial sediment samples were collected from eleven sites in the Northrup Creek to determine if phosphorus levels in the creek were correlated to the type of land use occurring in specific sections of the watershed. The results of this study were not statistically significant and could not be used to support the hypothesis statement that agricultural areas of the catchment would have high levels of organic phosphorus and residential areas would have high levels of inorganic phosphorus.
