I. INTRODUCTION

The objective of this project was to collect and analyze sediment from Houghtaling Island, an upland disposal site in the Hudson River, New York. This work was conducted in accordance with Appendix B, Attachment 1, of the technical manual entitled “The Management and Regulation of Dredging Activities and Dredged Material in New Jersey’s Tidal Waters” (Dredging Manual).

Aqua Survey, Inc. (ASI) performed all sampling and physical analyses (grain size distribution, percent moisture, and total organic carbon analysis). Chemical analysis of the samples was contracted directly with the analytical laboratory, Battelle, and its subcontract lab, Eurofins TestAmerica, Pittsburgh, PA. Their analytical results are not included in this report.

IV. MATERIALS AND METHODS

All sampling and testing were performed in accordance with Appendix B, Attachment 1 of the technical manual “The Management and Regulation of Dredging Activities and Dredged Material in New Jersey’s Tidal Waters” (NJDEP Dredging Manual), October 1997.

A. Sampling

Test sediment from ten locations was collected from Houghtaling Island by ASI personnel on March 22-23, 2022.

The all-terrain Geoprobe used for sampling was positioned using a Trimble NT200D Differential Global Positioning System (DGPS).

Sediment was collected using a 5 foot direct push tube with rigid liner.

Project depth was 35 feet below ground surface.

For each core, samples were collected at three intervals: 0-35 feet, 0-25 feet, and 25-35 feet.

The cores were inspected and photographed and the characteristics were recorded on Sediment Core Logs. All samples were assigned unique ASI sample numbers. All samples were received in good condition at ASI in Flemington, NJ and stored at 2-4 °C.

See Figure 1 for the site map, Table 1 for the DGPS coordinates, and Table 2 for sample identification numbers.

The appendices contain all supporting documentation including sediment core logs (Appendix A), photographs (Appendix B), chains of custody (Appendix C), sample use forms (Appendix D), grain size distribution (Appendix E), and TOC raw data (Appendix F).

B. Homogenizing

Each of the thirty sediment samples was carefully homogenized using a stainless steel mixer. This procedure followed the specific guidelines found on pages 9-11 and in Appendix A of the Dredging Manual and in ASI’s standard operating procedure SOP/PRP/008. Samples were mixed until uniform in color and texture.

Sample identification numbers can be found in Table 2.

Sub-samples of each of the sediment samples were reserved for the appropriate physical and chemical analyses.

C. Physical Analysis and Total Organic Carbon

Sub-samples of each of the cores were analyzed by ASI for grain size in accordance with the Standard Test Method for Particle-Size Analysis of Soils, Designation: D422-63 (Re-approved 2002).

Total Organic Carbon (TOC) was also determined at ASI based on the guidance from EPA Office of Solids Waste and Emergency Response SW- 846 Method No. 9060 (Volume IC, Chapter 5, Revision 0, 9/86). The instrument for this analysis was the Teledyne Tekmar LSS Boat serial number (US18208024R) connected to Teledyne Tekmar Lotix Analyzer serial number (US18214013R).

See Appendix E for the grain size distribution and percent moisture raw data and Appendix F for the TOC raw data.

V. PHYSICAL ANALYSIS RESULTS

The results of the analyses for grain size distribution and total organic carbon for the sediment samples are provided in Table 3.
