Purex Industries - Millville Site Remediation Program

The site occupant, a former subsidiary of Purex Industries, operated an aircraft engine aintenance and repair facility since 1946 at the Millville Airport. Various VOCs (gasoline, jet fuel, degreasers) discharged to the environment resulting in a 1,200-foot-wide, 3,500-foot-long, dissolved ground water contaminant plume. Additionally, two free phase floating product jet fuel plumes were present onsite.  One was located in the administrative building area and the other along the north-south taxiway.

A full scale RI/FS/RD was performed followed by pilot testing, final design, construction anagement, start-up, and O&M services for a multi-systems remediation program.  The remedial project utilized two product recovery systems (2), two soil vapor extraction system (2), and UV/Oxidation technology for contaminant destruction.


Fresh Kills Landfill - Professional Services to Support the Improvement of Operations  

GRB was responsible for the following tasks:

1) Identifying all permits, certifications and notifications required for the successful permitting of the Fresh Kills Landfill.

 2) Preparing a Regulatory requirements Report that identified and discussed in detail the technical and administrative requirements for each permit application, certification or notification required.

3) Establishing a line of communication between permitting agencies, the NYCDOS and the prime contractor in an effort to establish a professional rapport as it relates to permitting.

4) Meeting key regulatory personnel who have technical and administrative influence over the permitting process.

5) Reviewing and evaluating pertinent NYCDOS studies.


U.S. Army Corps of Engineers - Ecosystem Restoration and Mitigation Planning

This project involves the construction of features for flood protection along the Passaic River in the Town of Harrison, New Jersey.  The authorized plan for flood damage reduction includes a total of 7,450 linear feet of levee and floodwall with eight closure structures.  The levees will total 1,750 feet in length with an average height of 6.5 feet and an average base width of 50 feet.  The floodwall portion will be 5,700 feet in length and will have an average height of 6.2 feet.

The South 1st Street floodwall system will begin on the east side of Passaic Avenue just south of the NJ Transit rail line bridge structure and extend to the South 4th Street bridge embankment.  An additional section of floodwall to prevent flanking will be constructed running north adjacent to Cape May Avenue, to the Conrail bridge embankment.  Interior drainage facilities will be provided by new gravity culverts with flap gates and sluice gates, along with three pumping stations.  


TBTA Brooklyn Battery Park Tunnel Project

GRB is responsible for project monitoring management and inspection services for tunnel decontamination and abatement in response to 9/11 events at the Brooklyn Battery Park Tunnel in Brooklyn, New York.  GRB drafted a Quality Control Plan prior to commencement of project.  QC Plan served as work conduct guide for GRB oversight personnel and abatement subcontractor
personnel.  GRB determined abatement work schedules, safety details and report submittal procedures.  GRB created progress drawings using AutoCAD 2000.  Drawings were used as discussion tools during meetings with the TBTA.


Williamsburg Bridge Rehabilitation Project

GRB performed Phase I and II Environmental Assessments at 20 properties adjacent or under the bridge in accordance with NYSDOT environmental guidelines. GRB also prepared a site remediation report that identified, evaluated, and recommended various remedial actions, and prepared bid specifications in accordance with NYCDOT/NYSDOT requirements.


Operations & Maintenance - U.S. Navy

GRB currently provides all labor, supervision, tools, materials, equipment, and transportation necessary to maintain and operate multiple site remediation systems at the Patuxent River Naval Air Station located in Maryland.  The 4- year contract is valued at $2.5 million.  GRB provides site mechanics and engineering support to ensure the continued operability of the remediation
systems.  This entails providing preventative maintenance (including required repairs and installation of replacement parts) and preparing monthly and annual reports and estimates.  GRB attends quarterly meetings with the Navy and state regulatory agencies to provide updates on the on-going remedial program.


Groundwater Remediation/Site Investigations

GRB has 19 years of experience in conducting cost-effective site investigations to better conceive the nature and extent of contamination and potential environmental liabilities. We apply innovative rapid field screening techniques, focused feasibility studies, groundwater modeling, and risk assessment tools to save time and money during the investigation and design phase of projects. In addition, we have the quantitative skills to evaluate the performance of a proposed remedy and the practical experience to design and implement remedial actions. This includes excavation, soil vapor extraction, pump-and-treat, and other remedial alternatives.
