The River Run program is a monthly sampling event consisting of 10 stations in the mainstem of the St. Johns River.
Goals of this program are to monitor water quality trends for nutrients and their impacts. Information collected will to assist in establishing Total maximum Daily Loads (TMDLs) for the lower St. Johns River in Duval County. Parameters measured include field parameters: dissolved oxygen, pH, temperature, salinity, and specific conductance. Laboratory analysis includes: nutrients, chlorides, turbidity, total suspended solids (TSS), color, biochemical oxygen demand (BOD), fecal coliform bacteria and certain metals on a less frequent basis.
