Nutrient and sediment loading into Lake Ontario from tributaries impacts the water quality of nearshore waters. Sources of pollution such as runoff of sediments and nutrients, animal and human wastes, agricultural chemicals, and industrial discharges can lead to water quality issues. Through stressed stream analysis, the Black Creek watershed was segmented into small geographic units and water samples were taken to identify sources of; total phosphorus, soluble reactive phosphorus, total nitrogen, nitrate, total suspended solids, and total coliform bacteria. Spring Creek was found to have the high nitrate and total nitrogen on average (2.95 mg/L and 3.25 mg/L) and was segmented to find the source. Sources of impairment include; confined animal feeding, state pollutant discharge elimination system sites, and a community leach field. These findings will be inputs for the soil and water assessment tool (SWAT) to model potential best management practices to improve water quality in the watershed.
