Release of Sediment-Bounded Contaminants Sample Clauses

Release of Sediment-Bounded Contaminants. It is assumed the backfilling of sediment from xxxxxx barge or TSHD would expose the sediment to the entire water column. While the majority of sediment stays close together, about 3% of sediment would be entrained into the water column. Seawater would act like a solvent to extract contaminants from the entrained sediment. The dissolved contaminants would be carried away by water current, eventually reaching the nearby WSRs through advection and diffusion. To simulate this process, it is conservatively assumed 100% of the contaminants from the entrained sediment would be lost to the water column and the contaminant levels of the sediment would be at the corresponding UCEL for all contaminants. Then an inert tracer dispersion model would be conducted to simulate the dispersion of contaminants. The dilution achieved at the WSRs would then be factored in with the equilibrium concentration of contaminants in seawater to estimate the contaminant concentration at WSRs, for assessment against the proposed assessment criteria shown in Table 5.2. The dredging of marine sediment for the construction of CMPs would also result in disturbance to bottom sediment and potential release of sediment-bounded contaminants. Surface grab sediment samples were collected in mid-2020 to determine the level of contaminants in sediment within the majority of the Study Area. The sediment quality results are presented in Appendix B for reference. The highest contaminant levels among all stations are presented in Table 3.3 alongside with the LCEL and UCEL for comparison. As shown, none of the contaminant levels exceed the
