The purposes of this report are to 1) assess and document the occurrence and concentrations of selected pharmaceuticals and other organic wastewater compounds in WWTP influent and effluent, groundwater, canal water, and canal sediment samples at selected sites in Miami-Dade County; 2) assess the persistence of these compounds during wastewater treatment by comparing influent and effluent concentrations, loads, and seasonal variations, and by calculating percent reduction of individual compounds during treatment at each plant; and (3) assess the potential transport of these compounds from recharge areas through the groundwater system and into the canal system by comparing effluent concentrations at the HSWWTP with concentrations in nearby groundwater, nearby canal water and bed sediments, and more distant canal water and bed sediments.
