Environmental and Anthropogenic Impacts on Surface Water Quality in a Mixed-use Watershed

ABSTRACT Degradation of urban surface water quality has increased the importance of understanding the spatial and temporal distribution of pollutants within aquatic systems. Poor water quality damages aquatic habitats and poses a human health risk. The purpose of this study was to investigate environmental and anthropogenic factors that impact water quality in the Rock Creek Watershed in Maryland and the District of Columbia by monitoring microbiological (E. coli and total coliforms), chemical,
