Study Results from U.S. Environmental Protection Agency (EPA) Update Understanding of Biological Markers (Quantitative Fecal Source Characterization of Urban Municipal Storm Sewer System Outfall 'wet' and 'dry' Weather Discharges).

A study conducted by the U.S. Environmental Protection Agency (EPA) in Cincinnati, Ohio, focused on quantifying fecal sources in urban stormwater discharges. The research found that human, pet, and urban wildlife all contribute to water quality in storm outfall discharge, with varying pollutant sources based on weather conditions and land use. The study suggests that genetic-based fecal source identification methods combined with GIS land use mapping can enhance stormwater management in urban areas. The research has been peer-reviewed and provides valuable insights into improving water quality in urban environments. [Extracted from the article]
