Outcomes
  • Latest research on hexavalent chromium was used for highest report accuracy
  • Our chromium risk assessment was used by the clients, regulatory agencies, and the courts
  • Calculated risk for residential and commercial receptors to determine risk to the community.

The case of Hackensack Riverkeeper versus Honeywell International was a major litigation project related to the cleanup of chromium contamination at 12 sites in Jersey City, New Jersey. The sites were designated as Study Areas 5 and 6 by the New Jersey Department of Environmental Protection. 

The site includes a former chromium ore processing facility and several areas where the ore residue was used as a fill material. The sites had ongoing industrial activities for approximately 100 years. Activities included wet and dry industrial packaging operations, production of specialty chemicals, steel production, cutting and rolling operations, etc. Hexavalent chromium impacts were identified at the site, which is used as both a residential and commercial area. Several remedial and demolition activities had been conducted at the site. 

What We Did

The Risk Assessment and Management (RAM) Group, a business unit of Gannett Fleming, provided technical litigation support related to Study Area 5, as the plaintiffs were unable to settle the issue related to these properties. As part of this project, the RAM Group extensively reviewed New Jersey’s remediation standards, had discussions with New Jersey’s regulatory agencies, and calculated risk-based target levels using a variety of fate and transport models, toxicity values, exposure pathways, and land use conditions.  

Using the latest toxicological studies on hexavalent chromium and incorporating the new information into the risk assessment, the RAM Group provided a high level of satisfaction to clients, regulatory agencies, and the courts, which has resulting in continued recommendations from lawyers for the RAM Group to perform additional follow-on work.

Key Features

  • Extensive search of historic and current literature on hexavalent chromium, including its uses and toxicity
  • Regulatory interaction on chromium regulatory levels, new toxicity information, and process of rule making
  • Revision of NJDEP’s human health based criteria (HHBC) for hexavalent chromium based on recent developments on hexavalent chromium toxicity
  • Comparison of the updated criteria with the current NJDEP soil remediation criteria and groundwater standard, as well as an explanation of the differences
  • Evaluation of all complete exposure pathways for the site
  • Calculation of the risk for residential and commercial receptors
  • Provision of rebuttal reports for the expert reports prepared by the opposing side of the litigation
  • Response to rebuttal report for the RAM Group Risk Assessment Report.
