Underground Storage Tanks Remediation in Newark, NJ

Project included several gasoline station underground storage tanks (UST) areas of concern

Equity provided Licensed Site Remediation Professional (LSRP) services and conducted due diligence activities for the Atco Products metal stamping facility located in Newark, NJ.  Based on the Preliminary Assessment (PA) which indicated that there were several gasoline station underground storage tanks (UST) areas of concern, an initial site investigation (SI) was conducted. 

The SI was completed to determine the presence of gasoline related contaminants in onsite soils.  The analytical results of the initial soil samples collected identified soil contamination and the potential for groundwater contamination as well. 

The project included the detailed review of the site history, the preparation of a Remedial Investigation Work Plan (RIWP) and the implementation of the work plan which included the delineation of soil and groundwater contamination via the installation of soil borings, temporary well points and monitoring wells.  Because groundwater contamination appears to have migrated off-site, Equity was responsible for obtaining access agreements from adjacent property owners and obtaining street and sidewalk opening permits for the County Right-of-Way (ROW).  Soil and groundwater data was evaluated to determine an appropriate Remedial Action (RA) for the Site and address potential Order of Magnitude concerns based on new cleanup criteria.  It was determined that the course of action would be to remediate the groundwater and complete a Deed Notice for the soil. 

Groundwater remediation consisted of the installation of seven injection wells across the Area of Concern and multiple rounds of injection with various reagents to stimulate in-situ bio-remediation.  The necessary NJDEP Permit-By-Rule for groundwater injection was obtained and re-issued as the treatment took longer than originally anticipated.  After numerous rounds of treatment, the applicable groundwater cleanup criteria could not be met.  Equity is currently evaluating options to further treat the contaminated groundwater or establish a Classification Exception Area (CEA) for the site.

Equity, on behalf of Atco Products, prepared an application for remediation funding through the Hazardous Discharge Site Remediation Fund (HDSRF).  The HDSERF application required that Equity develop a detailed cost estimate for the remedial investigation through remedial action for the site.  The cost estimate included permitting, public notice/participation, preparation of various workplans and reports required by the Technical Requirement for Site Remediation 7:26E (Tech Regs).
