How EWMA Utilizes Enhanced Bioremediation To Gain Regulatory Closure For Clients

Subsurface Characterization

• Hydrogeologic Investigations
• Sensitive Receptor Evaluations
• Conceptual Site Model (CSM) Development
• Evaluation of Chemical and Biological Conditions
  • Concentration, Distribution, Trends, and Changes of Contaminants
    • Groundwater and Sorbed-Mass / Matrix Diffusion
  • Presence of Degradation Indicators and Daughter Products
  • In-Situ Geochemical Conditions
  • Microcosm Census and Diversity (qPCR and Sequencing)
  • Stable Isotope Analysis (CSIA)

Remedial Design / Construction Oversight

• Bench and Pilot-Scale Testing
• Permit-By-Rule (PBR) Applications/Approvals
• Design & Construction of Injection Point/Well Networks
• Baseline Sampling and Monitoring

Additional Field / Contractor / Consulting Services

• Injection of Amendments (Biostimulation)
  • Enhanced Reductive Dechlorination (ERD)
  • Anaerobic Oxidation / Nitrate Enhanced Bioremediation (NEB)
  • Aerobic Oxidation
• Injection of Appropriate Bacteria (Bioaugmentation)
• Post-Injection Sampling and Monitoring
• Evaluation/Interpretation and Presentation of Results
• 3rd Party Data Review and Fact/Expert Testimony 

What Differentiates EWMA Bioremediation Services and Products?

• Extensive Experience Working Within Variiou Subsurface Formations
• Long Recognized Need to Address Sorbed Mass and Matrix Diffusion in the Remedial Strategy

The Root Cause of Rebound –

• Abundant Experience with Other Remedial Techniques that Ultimately Underperformed

 Lessons Learned –

• Customized Injection Programs (Amendments and Methods) for Treatment of Chlorinated Solvents, Aromatic Solvents, and Petroleum Hydrocarbons
• Technical Support / R&D Capabilities from Laboratory (IAL)
• Focus on Improved Distribution and Diffusion of Amendments Into / Through Formation
• Strategic Focus on Transition to Monitored Natural Attenuation (MNA) Approval –  REGULATORY CLOSURE IS THE GOAL!!
