  • Nonpoint source pollution is the leading cause of in-stream water quality impairments, with pathogens alone responsible for more than 40% of all such impairments in North Carolina. Without a concerted effort to assess and manage these overland pollutant sources from a comprehensive approach, there will continue to be minimal progress toward finally realizing the goals of the Clean Water Act. This work addresses nonpoint source pollution through the development of a fully calibrated and validated Hydrological Simulation Program-FORTRAN model for Northeast Creek Watershed, as well as the creation of a linear optimization model for microbial nonpoint source Best Management Practice (BMP) selection. Based upon optimized model results, there would need to be an investment in structural and non-structural BMPs of over $20,000,000 throughout the course of the next twenty years in order for Northeast Creek to meet in-stream regulatory requirements.
