NJ Marine Sediment Data from the National Coastal Condition Assessment 2000-2006 and 2010 Bob Schuster NJDEP Water Monitoring and Standards Bureau of Marine Water Monitoring NJ Water Monitoring Council September 21, 2016
Chemical Sediment Sampling Sample design is probabilistic. This work starting in 2000 gave the first Statewide marine sediment sampling. Sediment samples collected using top 2 cm of sediment collected using a Van Veen sampler. 364 sampling locations for the 8 years of sampling. Samples analyzed for PAH s, Pesticides, PCBs, Metals, sediment toxicity. Data Analysis for this presentation was performed on 10,789 results for PAH s, Pesticides, and Metals with ERL and ERM values.
Marine/Estuarine Effects Range-Low (ER-L) and Effects Range-Median (ER-M) Long et al., 1995 ERL - adverse impacts to sediment benthos in approximately 10% of studies ERM adverse impacts in approximately 50% of studies

Overall Results 1 % (128) of the results exceeded an ERM 100 are from the NY-NJ Harbor/Hudson area 13.8% (1487) exceeded an ERL 707 are from the NY-NJ Harbor/Hudson area 59 stations (16%) are in the NY-NJ Harbor/Hudson area
Summary Largest number of ERM and ERL exceedences are from the Passaic River (6 stations of the 364). Mercury is the largest number of ERM exceedences. Metals As, Hg, and Ni at the top, are most of the exceedences of ERLs.
