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.

Groundwater Monitoring Event Adjacent to Riverside County Park in Lyndhurst, NJ [April 2013]:
The week of April 8, 2013, a groundwater monitoring event is to be conducted in
the mudflat adjacent to Riverside County Park in Lyndhurst, NJ.

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 posted on the Agency’s Diamond Alkali web site at http://www.epa.gov/region02/superfund/npl/diamondalkali/pdf/soilsamp_report.pdf
