Sediment Investigations

Low Resolution Coring (LRC) Supplemental Sampling Program (SSP) 2 [September to October 2013]

The 2013 LRC SSP2 was conducted to supplement the 2008 LRC data. Low resolution cores, high resolution cores, and surface grab samples were collected from 76 locations between RM 7 and RM 14 during the LRC SSP2. Additionally, sediment probing was performed in seven areas between RM 8.3 and RM 14.0 of the LPR and in the Third River. Click here to download the LRC SSP2 QAPP.  Due to the combined document size of the LRC SSP2 report, several files are provided in the Digital Library under Sampling\Passaic River for a more efficient downloading experience.

Freshwater Reference Sediment Quality Triad (SQT) and Background Sediment Study [November 2012]

Surface sediment samples were collected from above Dundee Dam as part of the Freshwater Reference and Background Conditions Study at 24 SQT locations and at 16 chemistry-only locations to provide background concentrations and reference data to support the baseline risk assessments.

LRC SSP [January to February 2012]

The 2012 LRC SSP was conducted to supplement the 2008 LRC data. Low resolution cores, high resolution cores, and surface grab samples were collected from 85 locations between RM 4 and RM 13 during the LRC SSP. Click here to download the LRC SSP QAPP. Due to the combined document size of the LRC SSP report, several files are provided in the Digital Library under Sampling\Passaic River for a more efficient downloading experience.

Benthic Program Surface Sediment and SQT Sampling [October to November 2009; August 2010]

Sediment toxicity, tissue contaminant concentrations, and bioaccumulation, surface sediment samples were collected from 111 locations (98 for SQT) in fall 2009, concurrent with studies of benthic communities. In addition, concurrent with sampling of benthic forage fish tissue contaminant concentrations, surface sediment samples were collected in summer 2010 from 21 locations.

Cooperating Parties Group (CPG) Sediment Sampling Work Plan [July 2008]:

A group of 73 companies, named the CPG, has taken over implementation of the 17-mile study (Superfund program side), under EPA oversight. This Work Plan describes the first comprehensive sampling of the sediments of the 17-mile study area. Maps of the sample locations (click here), field procedures (click here) and an investigation into how PCBs move from sediment particles into water (click here) are also included. The work described in these documents is scheduled to be done in the Summer-Fall of 2008. Each of these files is very large, so please allow some time for downloading them.

Work Plan, Maps and Quality Assurance Project Plan (QAPP) [August 2005]:
This Work Plan presents a united overview of the sampling activities and other investigations being conducted for the Lower Passaic River Restoration Project. This Work Plan is a dynamic document that will be amended as the project evolves and additional work phases are planned. Individual activities presented in the Work Plan are described in more detail in their own field sampling plans, as shown below. Attachment B to the Work Plan, the Geochemical Evaluation (Step 1) is provided on the Conceptual Site Model Page of this website Also available is a Quality Assurance Project Plan (QAPP) that details the planning processes for collecting data and describes the quality assurance and quality control activities developed for this project.

Dundee Lake Sediment Coring [December 2006-January 2007]: This survey collected sediment cores from above Dundee Dam and will analyze them for a number of contaminants, including dioxins, PCBs, metals, PAHs, and pesticides. The data will be used to determine the depositional history and concentration of contaminants in the sediments above Dundee Dam. To review the QAPP amendment for this work, click here. To view the QAPP amendment dated March 6, 2007, click here.

Hydrodynamic Survey [July 2004-July 2005]:
This survey measures how the river flows, how sediments move, and how the water's salinity and temperature change with the tides throughout the year. The survey is being done in two coordinated phases: 1) data collected in the lower 6 miles of the river are being used to help predict how sediments might be transported during the Dredging Pilot; 2) data collected in the upper 11 miles of the river are being combined with the data collected in the lower 6 miles for use in an overall effort to model how sediments and contaminants move throughout the 17-miles of the river. To review the work plan for Phase I, click here . To review the work plan for Phase II, click here

To download the hydrodynamic data that was collected using instruments moored in the Lower Passaic River, click here and also click here for the data collected by Rutgers University. For further information regarding data collected by Rutgers University click here

Please consider the following data quality parameters when using the downloaded hydrodynamic data:

  • For the data collected in the lower 6 miles of the river, final positioning of the moorings differed from proposed locations. In some instances, sensor arrays were recovered several hundred meters downstream of the original deployment location. To review the final coordinates for each mooring included in the survey, click here.
  • For the data collected in the upper 11 miles of the river, users should note that the sensors, particularly the pressure sensors, were not replaced at precisely equivalent depths throughout the survey, following regular retrieval and data download/battery replacement. Care should be taken when multiple mooring results are to be compared, even from the same mooring location.
  • The acoustic doppler current profile (ADCP) data from mooring no. 1 could not be retrieved due to sensor corruption. To view/reduce any of the ADCP data, users must download the sensor manufacturer's post-processing software tools for the RBR Logger at the following link: http://www.rbr-global.com/software.htm.

Bathymetric Survey [October 2004]:
This survey measures how deep river bottom sediments are under water. The agencies will compare this year's depths to previous years' depths to show where river sediments are accumulating and where they are scouring away. Maps showing the survey results are being prepared.

Partner Agency Work Plans [2005-2006]:
The Partner Agencies implemented a number of surveys to collect sediment cores and river water samples and analyze them for a number of contaminants, including dioxins, PCBs, metals, PAHs, pesticides.  Field Sampling Plan Vol. 1 describes these surveys in detail (the attachments to this document are available upon request to Alice Yeh at yeh.alice@epa.gov).  The Partner Agencies also drafted Field Sampling Plan Volume 2 that describes biological sampling work (the figures for this document are available upon request to Alice Yeh at yeh.alice@epa.gov).  That sampling work was not completed, but Field Sampling Plan Volume 2 formed the basis for the biological sampling work done in 2009 described above. Throughout the project, surveys will bewere conducted to characterize the physical properties of the Passaic River, focusing on the candidate restoration sites in the watershed. These surveys include the bathymetric survey described above, geophysical surveys, soil investigations, cultural resource and real estate investigations, among many others. Field Sampling Plan Volume 3 describes these surveys in detail. Click here for a report of the geophysical surveys conducted in 2005.

Erosion Testing [May 2005]:
Sediment cores were collected from the Passaic River and eroded using two techniques. The data will help explain how sediments are transported by river flow under normal and storm conditions.
