Title: Properties of New York/New Jersey Harbor Sediments

Abstract

Sediments found in waterways around the world may contain toxic compounds of anthropogenic origin that can harm the environment and human health. As a result, it is often necessary to remove them and find disposal methods that are environmentally and economically acceptable. Here, we report on results obtained in an experimental program to characterize the nature of the sediment contamination. The objective was to gain a better understanding of the properties of the sediments to develop better methods for understanding the fate and transport of the contaminants and for improving methods for their removal from the sediments. Our investigations made use of X-ray facilities at the Brookhaven National Synchrotron Light Source and the European Synchrotron Radiation Facility at Grenoble, France. The experiments included: measurements of the microstructure of the sediments using computed microtomography, X-ray absorption, and fluorescence microscopy with resolutions as low as 0.2 micrometers to obtain information on the relationships of organic and mineral components of the sediments and on the distribution of contaminants on the surfaces of the sediment grains, investigation of functional groups of chemical compounds using X-ray absorption near-edge spectroscopy and Fourier transform infrared spectroscopy. Scanning electron microscopy and electron probe measurements were made to ascertainmore » the morphology of the sediment surfaces and the distribution of metals on individual sediment grains.« less

  • Sediments found in waterways around the world may contain toxic compounds of anthropogeilic origin that can harm the environment and human health. As a result, it is often necessary to remove them and find disposal methods that are environmentally and economically acceptable. Here, we report on results obtained in an experimental program to characterize the nature of the sediment contamination. The objective was to gain a better understanding of the properties of the sediments to develop better methods for understanding the fate and transport of the contaminants and for improving methods for their removal from the sediments. Our investigations mademore » use of x-ray facilities at the Brookhaven National Synchrotron Light Source (NSLS) and the European Synchrotron Radiation Facility (ESRF) at Grenoble, France. The experiments included: measurements of the microstructure of the sediments using computed microtomography, x-ray absorption, and fluorescence microscopy with resolutions as low as 0.2 micrometers to obtain information on the relationships of organic and mineral components of the sediments and on the distribution of contaminants on the surfaces of the sediment grains, investigation of functional groups of chemical compounds using x-ray absorption near-edge spectroscopy (XANES) and Fourier Transform Infrared Spectroscopy (FTIR). Scanning electron microscopy (SEM) and electron probe measurements were made to ascertain the morphology of the sediment surfaces and the distribution of metals on individual sediment grains.« less

  • The U.S. Army Engineer District, New York, dredges several million cubic yards of sediment annually to maintain Federal navigation channels in New York and New Jersey Harbor. Most of this dredged material has characteristics that allow its disposal into open water or ocean sites. However, contaminant concentrations in some of the materials have led to this and other investigations of alternate management techniques for dredged material that is unacceptable for open-water disposal. These alternatives include ocean disposal with capping, coastal borrow pit disposal with capping, land-based or in-water confined disposal, and treatment of sediment to reduce the contaminant concentrations tomore » levels acceptable for unrestricted disposal or beneficial uses. This report assesses available treatment and disposal altenatives for dioxin-contaminated dredged material from New York/New Jersey Harbor. Included in the assessment of treatment altenatives are a survey of available options, results from bench-scale tests of selected treatment technologies, development of the overall process train for promising treatment alternatives, an assessment of the feasibility of implementing the alternative, preliminary cost estimates, and a comparison of alternatives. Disposal alternatives are discussed on a similar basis and are compared with treatment altenatives.« less
  • The bay areas surrounding New York/New Jersey Harbor are naturally shallow, acting as catchments for river-transported sediments and solids from surface point and nonpoint sources. Dredging is required to maintain navigability for large cargo ships. Annually more than 5 million yd{sup 3} of sediments has been dredged to maintain harbors and waterways for New York and New Jersey Harbor. Currently about 80% of dredge sediments are considered clean and ocean disposed of at the designated Mud Dump site, located approximately 6 nautical miles south of Rockaways. In order to be disposed of at the Mud Dump site, the Marine Protection,more » Research and Sanctuaries Act of 1972 (MPRSA) requires the evaluation of the environmental impact using criteria developed by the USEPA and published through 40 CFR Parts 220 to 228. Based on the results of the evaluation, the sediments are assigned one of three categories which defines their potential disposal method--Category 1 sediments (acceptable for ocean disposal), Category 2 sediments (acceptable for ocean disposal with specific mitigation), and Category 3 sediments (not permitted for ocean dumping). A growing public concern over the impacts of contaminated sediments, in addition to a more stringent set of criteria having been established, is expected to significantly increase the volume of sediments requiring special handling or disposal, due to the inability to dispose of Category 3 sediments at the Mud Dump Site. Hence, the objective of this project is to study the contaminant characteristics of sediments in the Newark Bay, Arthur Kill, and Newtown Creek area and identify and evaluate alternative methods for managing or decontaminating sediments that are practical, cost-effective, and protective of human health and the environment.« less
