Detection of Newly Deposited Sediments Via Frequency Response Measurements: Dredging Residuals Density Profiler (DRDP)
Welp, T., M. Tubman, D. Wilson, P. T. Puckett, N. Greiser, AND B. A. SCHUMACHER. Detection of Newly Deposited Sediments Via Frequency Response Measurements: Dredging Residuals Density Profiler (DRDP). U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-09/120, 2009.
An EPA Interagency Agreement (IAG) was signed between the ERDC and EPA’s Environmental Sciences Division (ESD) of the Office of Research and Development’s National Exposure Research Laboratory, the objective of which is to have ERDC modify the ADMODUS probe (a navigation fluid mud survey system successfully demonstrated in the Gulfport, MS, navigation channel and in the laboratory) for use in characterizing dredge residuals for environmental dredge projects. Specifically, the system is to be optimized to identify the dredging residuals and facilitate sediment sampling efforts in conjunction with EPA’s new Undisturbed Sediment Sampler (USS) designed for environmental dredging projects.
The laboratory evaluation of the DRDP summarized in this report was conducted for the U.S. Environmental Protection Agency (EPA). Dr. Brian Schumacher of the EPA’s Environmental Sciences Division (ESD) of the Office of Research and Development’s National Exposure Research Laboratory - Las Vegas (ESD-LV) is the Project Officer responsible for direction and oversight of the project. George Brilis, ESD-LV, is the Quality Assurance (QA) Manager responsible for ensuring that the project conforms to the quality standards set by the EPA.
