“…The improvement in PCB and chlorinated hydrocarbon levels in sediments along the main stem of the Hudson and in Jamaica Bay and in levels of 2,3,7,8-TCDD in sediments from western NY/NJ harbor have been discussed in detail elsewhere (2)(3)(4)21). These trends reflect the success of efforts to limit inputs of contaminants to natural water systems through restrictions on the use of specific compounds, upgrades of municipal sewage treatment facilities, control of …”

“…A few of the more recent particle samples were suspended matter collected on precombusted quartz fiber filters using a largevolume in situ pumping system (5). Radionuclide analysis of sediment core sections to obtain dating information was performed by nondestructive 'y-ray spectrometry (1)(2)(3)(4). Extracts of dated core sections for PCB, chlorinated hydrocarbon pesticide, and dioxin analyses were prepared using soxhlet extraction and column chromatography cleanup.…”

“…Levels of chlordane are reported in terms of y-chlordane, which comprises about 15% of technical chlordane (9) Figure 1). In both cases, the known history of discharge provides additional dating information in sediments from nearby sampling sites (2,14). A near-ideal depth profile of fallout 137Cs activity in a sediment core from the Batten Kill, a major tributary of the upper Hudson ( Figure 1, site 2) is shown in Figure 2.…”

“…The relative strength of this source has decreased over time, and since the mid-1980s, local NY/NJ metropolitan area sources, including discharge of municipal wastewater, appear to be responsible for the majority of PCB loading to the main-stem harbor sediments (2,14,23 Relatively low levels of 2,3,7,8-TCDD are associated with wastewater inputs (Figure 4, sites 9 and 10) and atmospheric inputs to the mid-Hudson River Basin were not detectable in our reservoir sediment samples ( Figure 4, sites 6 and 7). Also of note are the generally low levels in sediment samples from the upper Hudson basin.…”

Analyses of sections from dated sediment cores were used to establish geographic distributions and temporal trends of chlorinated hydrocarbon contaminant levels in sediments from natural waters of the Hudson River basin. Radiometric dating was based primarily on the depth distribution of 137Cs in the cores and on the occurrence of detectable levels of 7Be in surface sediment samples. Eighteen sampling sites included several along the main stem of the Hudson, its major tributaries, and components of the New York/New Jersey (NY/NJ) harbor complex. Drinking-water reservoirs were sampled to place upper limits on atmospheric inputs. Core sections were analyzed for polychlorinated biphenyls (PCBs), 1,1,1-trichloro-2,2-bis(pchlorophenyl)ethane (DDT)-derived compounds, chlordane, and dioxins. Sediment concentrations of most contaminants at most sites have decreased significantly since the mid-1 960s. The data provide a basinwide perspective on major point-source inputs of PCBs to the upper Hudson River and of 2,3,7,8-tetrachlorodibenzo-p-dioxin and DDT to the lower Passaic River. Evidence was found for significant but poorly characterized sources of PCBs and chlordane to the western NY/NJ harbor, and of highly chlorinated dioxins to the upstream sites on the main stem of the Hudson. The results indicate that analysis of dated sediment samples is a most effective and efficient monitoring tool for the study of large-scale geographic and temporal trends in levels of particle-associated contaminants.

The lower Passaic River is an operable unit of the Diamond Alkali Superfund site at 80 and 120 Lister Avenue in Newark, New Jersey, USA. Between 1948 and 1969, the Diamond Shamrock Chemicals Company and its predecessors manufactured chemicals such as pesticides and phenoxy herbicides, including 2,4,5-trichlorophenol, which is a precursor to 2,4,5-trichlorophenoxyacetic acid, one of the primary components used to make the military defoliant Agent Orange. A by-product of this manufacturing process was 2,3,7,8-tetrachlorodibenzodioxin (2,3,7,8-TCDD), and the site is considered the dominant source of 2,3,7,8-TCDD to the lower Passaic River and its environs. Several investigators have identified the ratio of 2,3,7,8-TCDD to total TCDD as a fingerprint for the site source. The present study presents data that establish polychlorinated dibenzodioxin/polychlorinated dibenzofuran (collectively, PCDD/F) congener and homolog fingerprints of soil and sump samples from the site. It then compares those fingerprints to the PCDD/F congener and homolog patterns in lower Passaic River sediments. The similarity of the patterns in lower Passaic River sediments to the site fingerprint indicates the site is the dominant source of the 2,3,7,8-TCDD in sediments within approximately the lower 14 miles of the lower Passaic River, excluding, for the purposes of the present discussion, Newark Bay. In addition, PCDD/F congener data indicate that the ratio of 1,3,7,8-TCDD to 2,3,7,8-TCDD is another marker of the site and corroborates the findings from the other fingerprints.
