Printer-friendlySediment Assessment and Management
About the Program
This program is responsible for the field collection of sediment samples, the identification of contanminants of concern and possible sources, and the preparation of reports and evaluation of impacts. In regards to dredging, the program develops 401 Certification conditions, the evaluation of in-water and riparian disposal options and the design of a monitoring regimen to evaluate compliance/impacts. A working knowledge of dredging issues and technology is sustained. The Sediment Assessment and Management Program provides an expert opinion on sediment related issues to other DEC units, Federal, State, and Local Government Agencies, and other interested/involved parties.
Hudson River Sediment and Biological Survey (November 2000)
Introduction
In 1997, the Division of Water submitted a proposal to the Hudson River Estuary Management Program (HREMP) to conduct biological monitoring within the lower Hudson River. The biological monitoring would occur at sites where sediment cores were to be evaluated for chemical and physical parameters that were funded under a different proposal under HREMP. Sediment and benthic samples were collected in the fall of 1998, between Albany (140.5 river mile) and Peekskill, NY (42 river mile).
Objective
The objective of this project was to characterize sediment quality using the triad approach. This approach uses sediment chemistry, toxicity results, and benthic assessments to describe the sediments. This approach has also been used to develop chemical specific sediment quality criteria (Chapman, 1986 ; Long, 1998 ).
