1 Delaware River Basin Commission Role of Sediments in Managing PCBs in the Delaware Estuary Gregory J. Cavallo, P.G. Thomas J. Fikslin, Ph.D. NJ Monitoring Council September 21, 2016
2 Presentation Outline Why sample sediment? PCBs concentrations from the Delaware Estuary collected for the Delaware Estuary Benthic Inventory (DEBI) project (2008) and DRBC efforts in 2010 Compare PCB homolog signatures Technical/Management Implications Discuss 2016 Sediment Sampling Effort
3 Why Sample Sediments? Roles of Sediment Interaction with water column Mediating the water column response Integrator of changes in water column concentrations Provide data on trends Providing assimilation capacity Pollutant removal mechanism
4 Principal Mass Loadings and Fluxes Upstream Boundary Load Schuylkill River Upstream Boundary Load Delaware River at Trenton, NJ C&D Canal (tidal boundary) Tributary Loads Atmoshpheric Wet / Dry Deposition Atmoshpheric Gas phase flux Contaminated Site Loads Non-Point Source Loads Point Discharge Loads CSOs LEGEND Ocean Boundary Mouth of Delaware Bay Sediment Sediment Flux External Loads (forcing functions) Fluxes and tidal boundaries
5 Mediating Water Column Response Past and current PCB loadings of PCBs result in the accumulation of contaminated sediment. Even if current loadings are substantially reduced, the water column will not immediately respond due to contributions of PCBs from the sediment. As clean sediments enter the water body, sediment concentrations will ultimately be in equilibrium with the water column concentrations.

8 DEBI Sediment Sample Collection Sediment samples were collected as part of the Delaware Estuary Benthic Inventory (DEBI) Program in Summer of 2008 Surface grab samples Young stainless steel grab 187 samples were received by the DRBC Samples were collected in Zones 4, 5 and 6 with an emphasis in Zones 5 and 6
9 PCB Analysis 52 samples were analyzed for PCBs 4 samples analyzed were from Zone 4 34 samples analyzed were from Zone 5 14 samples analyzed were from Zone 6 PCB samples were analyzed for all 209 congeners using EPA Method 1668 revision A by Axys Analytical Laboratories Analytical results are provided in pg/g dry weight Estimated Detection Limits of <1 pg/g (ppt) 90% of all congeners detected
