Sediment Quality of the Lower St. Johns River and Cedar-Ortega River Basin: Chemical Contaminant Characteristics
This report presents the findings of a basin-wide sediment quality assessment conducted within the lower St. Johns River basin by the St. Johns River Water Management District from 1996 through 1999. A total of 135 sites were selected and analytically assessed for sediment quality and the presence of contaminants. Sediments were analyzed for a number of constituents of concern that included more than 100 organic compounds and 20 metals. The objective of the project was to determine the presence, concentration, and distribution of potentially toxic organic compounds and metals, with areas of high concentration identified for more intensive sampling and characterization. The resulting data provide a first level screening analysis of a broad range of contaminants and enhance understanding of the overall contaminant burden of the sediments of the lower St. Johns River.
