Temporal Dynamics of Water Quality in Nancy Creek, Atlanta, GA

This study examines the temporal dynamics of water quality measurements along Nancy Creek in Atlanta, GA. Conducted by Joe Estep from the Georgia Institute of Technology, the analysis focuses on crucial parameters including dissolved oxygen, pH, conductivity, and turbidity over a 60-day period at two sites: Rickenbacker Drive and West Wesley. Key findings highlight the significant influence of precipitation on water quality, the non-normality of data sets, and the inconsistency of lag times between measured parameters.
