Chemical Contamination of Sediments in the Cedar-Ortega River Basin

This report presents the findings of an intensive sediment quality assessment conducted within the Cedar and Ortega River Basin by the St. Johns River Water Management District from 1998 through 1999. A total of 52 sites were selected and analytically assessed for sediment quality and the presence of contaminants. Sediments were analyzed for a number of constituents of potential 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, identify and evaluate the hazard posed and delineate the spatial patterns of the most problematic contaminants of concern. The resulting data were used in an assessment and evaluation of a broad range of sediment contaminants, which lead to the identification of the source areas and initiation of management efforts to remediate contamination of the Cedar-Ortega River Basin.
