Brinkerhoff Environmental Services, Inc. was retained to conduct remedial investigation and remedial action activities at the former Whitlock Cordage Facility located at 160 Lafayette Avenue, Jersey City, Hudson County, New Jersey. On May 30, 2003, Brinkerhoff completed a Phase I Environmental Site Assessment (ESA)/Site Investigation (SI) for the site. Based upon the findings of the ESA/SI, four areas of concern (AOCs) required further investigation. Said AOCs are described as follows:

  • Open Heating Oil UST Spill Case
  • Historic Fill Material and Debris
  • Historic Building Operations
  • Former Gasoline UST.

In order to address these AOCs, a soil and groundwater sampling program was implemented to evaluate the subsurface conditions and groundwater quality at the site.

Based upon the data presented in the ESA/SI and this Remedial Investigation Report/ Remedial Action Workplan (RIR/RAW), Brinkerhoff requested that NFAs be issued for AOC-1 and AOC-4. Brinkerhoff proposed to address the remaining AOCs (AOC-2 and AOC-3) via the installation of a cap combined with the establishment of a Deed Notice to address PAH contaminants remaining on the site. Brinkerhoff, on behalf of the property owner, requested separate RAW approval for soils to enable construction activities to move forward. Groundwater was addressed as a separate issue as discussed below.

Since the residual levels of PCE and 1,1-dichloroethane that remained in the property’s groundwater were above the NJDEP Groundwater Quality Standards, additional investigative/ remedial action was required before an NFA was requested. Brinkerhoff proposed the following: the installation of two monitoring wells to delineate the extent of impacted groundwater and determine if the contaminants were migrating from an off-site source; conducting two additional rounds of groundwater sampling and analysis to determine if natural attenuation was proceeding; and, if natural attenuation was not proceeding, conducting a rising head slug test to evaluate the hydraulic conductivity. The slug test was used in the calculation of a Classification Exception Area or Well Restriction Area, which was placed on the groundwater in AOC-3. Following completion of the work, an RAW was prepared and submitted to the NJDEP.
