Water Quality of Inflows to the Everglades National Park over Three Decades (1985–2014) Analyzed by Multivariate Statistical Methods

A three-decade analysis of water quality in inflows to the Everglades National Park reveals that rainfall significantly influences nitrogen and phosphorus concentrations, with increased precipitation leading to diluted nutrient levels. Cluster analysis identified four distinct groups among seven sampling stations, while principal component analysis highlighted total nitrogen (TN) as the primary pollutant, suggesting non-point sources dominate contamination. Best management practices (BMPs) effectively reduce organic nitrogen, but TN and total phosphorus (TP) remain critical focus areas for future mitigation. Increasing water transfer can temporarily improve quality, while submersed macrophytes offer a sustainable solution by absorbing nutrients and boosting dissolved oxygen levels.
