Summary:
Multiple tracers, such as DO, ammonia, TN, TOC, E. coli, TC, and Enterococcus were analyzed in order to identify and characterize trends in coastal water quality. This study focused on three factors; wastewater disposal and treatment alternative; season; and human population density. Samples were collected in representative sites of urban Broward County and of rural Taylor County, FL, for pair-wise comparison. Sites included areas connected to the public sewer network and served by on-site treatment and disposal system (OSTDS). Sampling activities were conducted through seasonal low and seasonal high water table elevation (SLWT and SHWT), and always on slack to outgoing tide. Different statistical tests were performed, including: t-Tests, correlation analysis, principal component analysis (PCA), and analysis of variance (ANOVA). Results suggested that water quality is lower: in urban sites compared to rural sites; in OSTDS sites compared to sewered areas; and SHWT compared to SLWT.
