River Mile 10.9

    

Final Design for removal of contaminated sediment from a mudflat in the Lyndhurst section of the Passaic River [November 2013]

Dredging of the removal area began on August 3, 2013 and was completed on October 4, 2013. Processing of the dredged material at the Clean Earth Dredge Technologies facility in Kearny, New Jersey was completed on October 18, and all dredged sediment and associated water was sent to approved out-of-state facilities for disposal. Mobilization for capping of the removal area began on November 5, and all site activities are expected to be complete by early 2014. All work is being overseen by EPA and its contractor. Below are links to the complete final design for the removal action, which is dated July 31, 2013. Note that this design has been approved by EPA except for Appendix J, which relates to the long-term operations and maintenance of the cap after it is in place. Appendix J will be posted when it is approved.

Pre-final Design for removal of contaminated sediment from a mudflat in the Lyndhurst section of the Passaic River now available

On June 18, 2012, EPA signed an agreement with 70 companies considered potentially responsible parties to remove contaminated sediment from a mudflat adjacent to Riverside Park in Lyndhurst, New Jersey. This area was discovered during the investigation of the Lower Passaic River Study Area, a 17-mile stretch of the Passaic from Newark Bay to Dundee Dam, and is being conducted prior to the selection of a final remedy for the entire study area. A preliminary design was submitted in August 2012 and has been revised to incorporate comments received from EPA, partner agencies, and other interested parties. The current pre-final design includes the removal of approximately 18,000 cubic yards of material from the river, followed by capping of the dredged area, and monitoring to assure the effectiveness of the action until a final remedy for the river is selected and implemented. Dredging is currently planned to start in Summer 2013. Note that testing of soil in the park was conducted in 2011 and contamination was not discovered at levels of concern. All material to be removed as part of this action is located in the river.

Seventy Companies Reach Agreement with EPA to Remove Highly Contaminated Mud from a Section of the Lower Passaic River

The EPA announced on June 18, 2012 that it has reached agreement with 70 companies considered potentially responsible for contamination of the lower Passaic River to remove approximately 16,000 cubic yards of highly contaminated sediment from a half-mile long area of the Passaic River in Lyndhurst, New Jersey at their expense.

Recreational Fields Sampling Results: Lyndhurst and North Arlington, NJ [March 2013]:

Following Hurricane Sandy, EPA collected soil samples in recreational fields in Lyndhurst and North Arlington, New Jersey to look into whether dioxins, PCBs and mercury may have been carried into the parks during flooding from that storm. The results showed that the measured concentrations of dioxins, PCBs and mercury present in soil were well below levels of concern. EPA had previously collected samples of surface soil in these parks in late 2011 and early 2012, in the aftermath of Hurricane Irene and Tropical Storm Lee, and those earlier results also showed that the measured concentrations of dioxin, PCBs and mercury were below levels of health concern. Based on its analysis, EPA does not plan on further sampling of recreational areas in this area and deems that cleanup actions on soil in the parks are not warranted. Further, this is the third round of post-storm event sampling conducted in this area and similar results have been found during each round. The sampling report is available upon request (see “Contact Us” page for EPA contact information).
