PHEnv conducted a Preliminary Assessment
(PA) and Site Investigation (SI) of this 17-acre site former Standard
Oil Refinery in accordance with the Technical Requirements for Site
Remediation (TRSR) to identify the presence of any potentially contaminated
AOCs resulting from existing or historic land uses, either on the
Site or adjacent properties, and if identified, to determine whether
or not any contaminants are present above the applicable unrestricted
use standard stipulated by NJDEP. The site is being evaluated
as part of the extensive brownfields redevelopment being conducted
in the southeastern portion of Jersey City.
Historical maps and aerial photographs dating back to the early
1900’s indicate that the site was part of the Standard Oil
Company Eagle Works.
The soil sampling and analysis program conducted at the Site consisted
of the conduct of 51
soil borings. The soil samples
were collected for chemical analysis to: (i) provide an initial characterization
with respect to the potential presence of contamination due to historic
uses of the site and were also evaluated in the field to determine
if fill material exists at the Site, (ii) to investigate the former
presence of underground storage tanks at the Site, (iii) to investigate
the potential for contamination to exist as a result of the operation
of an aboveground storage tank and pump house.

The groundwater SI consisted of the installation of temporary
well points at five locations suspected of having potential groundwater
contamination based upon historic and current uses. The results
of the PA/SI indicated the presence of petroleum product contamination
of both soil and groundwater at the site and metals contamination
of soil at the site.
PHEnv prepared and implemented a Remedial
Action Workplan. As part of the overall remediation, PHEnv
has designed and is currently operating an interim groundwater
treatment system to remove product as well as a hydraulic well point
system to dewater the areas subjected to tidal effects.
For groundwater, the focus has been to remove overlying oil-bearing
source soils and pump-and-treat remaining product. Because
of the proposed high-end residential use of the site, long-term
pump-and-treat is not an option. The site will be fully remediated
by September 2006 with submission of Remedial Action Reports to
follow shortly thereafter. |
