Since 1990, DRBC has periodically sampled tissues of resident fish species in the non-tidal and tidal portions of the main stem Delaware River. In the non-tidal portion, samples of smallmouth bass and white sucker are collected at three locations: Milford, Pa. (river mile [RM] 246), Easton, Pa. (RM 183), and Lambertville, NJ (RM 149). In the tidal portion of the river, samples of channel catfish and white perch are collected at five locations: Crosswicks Creek (RM 128), Tacony-Palmyra Bridge (RM 107), Woodbury Creek (RM 91), Raccoon Creek (RM 80), and Salem River (RM 58).
The samples are analyzed for PCBs, chlorinated pesticides, dioxins/furans, flame retardants, perfluorinated chemicals, mercury, and other metals. These data are used to track the progress of the PCB TMDLs that were established by the U.S. EPA in 2003 and to identify chemical compounds that may pose a risk to human health through fish consumption. These data are also forwarded to state agencies for their use in establishing fish consumption advisories for fish caught in the Delaware River.
Listed below are links to chemical contaminant data for fish and shellfish samples collected from the Delaware Estuary by a variety of organizations. The compilation focuses primarily on samples collected from the tidal waters between Trenton, N.J. and the mouth of the Delaware Bay; however, data are also presented for many non-tidal waters that drain to the tidal Delaware Estuary.
The data are presented in Microsoft Excel files and can be downloaded.
