Majda Rabah, PhD, PE, LSRP

Principal Engineer

Dr. Rabah is a registered Professional Engineer and a Licensed Site Remediation Professional (LSRP) in the State of New Jersey with over twenty-five years of experience in the planning, development, and management of complex environmental remediation projects under various State (NJDEP, NYSDEC, and SCDHEC) and Federal (RCRA and CERCLA) regulatory programs. Dr. Rabah has managed, designed, and overseen the implementation of investigation and remediation at numerous large-scale, multi-faceted environmental remediation projects with a wide range of contaminants (petroleum hydrocarbons, chlorinated solvents, PCBs, emerging contaminants, etc.) under complex geological conditions.


Dr. Rabah holds a PhD in Environmental Engineering from Stevens Institute of Technology. Dr. Rabah’s PhD research was funded by NASA to develop a gravity-independent grey water treatment system for space applications, a prototype of which was tested at the Johnson Space Center in Houston, Texas. Dr. Rabah is currently a Principal Engineer for Roux.

representative projects
  • Former Water Heater/Radiators Manufacturing Facility: Senior project manager and technical lead. The Site was undergoing active soil and groundwater remediation. Due to vapor intrusion concerns, an active sub-slab depressurization system was installed, operated, and maintained. Hot-spot soil excavation was conducted along with development of site-specific soil remediation standards and compliance averaging to bring the soil case to closure. Active in situ groundwater remediation was implemented to remediate chlorinated volatile organic compounds in the overburden aquifer.
  • Guidance and Navigation Manufacturing Facility: Technical advisor for the Industrial Site Recovery Act (ISRA)/Resource Conservation and Recovery Act (RCRA) 2020 site. An in situ remedial system was implemented for chlorinated solvents in soil (saturated zone) and groundwater. Work included monthly injections, groundwater sampling, soil investigation, surface water sampling, sediment sampling, and reporting to the New Jersey Department of Environmental Protection (NJDEP)/United States Environmental Protection Agency (USEPA). Vapor intrusion investigation and evaluation were conducted at the Site. Sub-slab soil gas impacts were identified, and long-term indoor air monitoring is currently conducted at the Site.
  • Former Printing Facility: Technical lead and regulatory advisor. Work included implementation of pilot-scale and full-scale in situ groundwater remedial system and monitoring program (in situ chemical oxidation injections [ISCOs] in bedrock along with pneumatic fracturing), application for and procurement of NJDEP permits (short-term and long-term permit-by-rule applications), vapor intrusion evaluation, and reporting to the NJDEP.
  • Former MGP Site: Project manager for remediation of soil. Work included delineation of dense non-aqueous phase liquid (DNAPL) in soil, DNAPL recovery pilot-scale test, soil excavation and off-site disposal, sediment dredging and restoration of an on-site/off-site creek, and wetlands mitigation.
  • Former Industrial Facility, Project Manager: This Site was remediated under the Brownfields Act. Work included report preparation to the NJDEP; implementation and evaluation of multi-phase site investigation/remedial investigation programs; QA/QC inspection of remediation and environmental construction activities; application for and procurement of NJDEP permits; co-development and implementation of remedial system operation, maintenance, and monitoring programs; coordination of hazardous discharge site remediation fund (HDSRF) grants and other remediation funding; and coordination of public outreach programs.
  • Lower Passaic River Superfund Site, Senior Project Manager: Responsibilities included preparing financial progress reports, budgetary planning and tracking, accounts receivable processing and tracking, monitoring and updating project schedule, preparing periodic cash flow analyses, and forecasting and preparing annual project budgets.
  • LSRP of Record for Several Sites Under ISRA and the Spill Act Discharge:
    • Several former FMC facilities in NJ
    • Several former Northrop-Grumman facilities in NJ
    • Several Johnson & Johnson facilities in NJ
    • Former Rockwell Automation, Hopewell, NJ
    • Former Bristol-Myers Squibb site, Hillside, NJ
    • Several ISRA sites in Fairfield, NJ
    • Several Spill Act Discharge sites throughout New Jersey
  • Grey Water Treatment in Immobilized Cell Packed Bed Reactors for Use Under Microgravity Conditions, SAE Technical Paper Series: 1999-01-1946, 29th International Conference on Environmental Systems, 1999

  • Development of a Gravity-Independent Wastewater Bio-processor for Advanced Life Support in Space, Water Resources Research, 2005

  • A Gravity Independent Biological Grey Water Treatment System for Space Application, Doctoral Dissertation, 2002
