Consulting and Engineering

NOREAS provides an integrated approach to consulting and engineering services on projects by combing effective communication with our clients, and engaging the appropriate expertise and technical resources. Our environmental projects incorporate inputs from geologists, hydrogeologists, chemists, microbiologists, engineers, and construction managers to develop a multi-disciplinary team approach to design solutions for remediation projects. A list of our environmental design areas are provided below:

  • Soil Vapor Extraction (SVE) Systems – solvents, and petroleum hydrocarbons
  • Air Sparging (AS) Systems – solvents, and petroleum hydrocarbons
  • Multiphase Extraction (MPE) Systems
  • Enhanced In Situ Bioremediation (EISB) – aerobic, anaerobic, bench and field scale implementation, and bioaugmentation
  • Biomonitoring – using both traditional and advanced techniques
  • In Situ Chemical Oxidation (ISCO) – using potassium permanganate, activated persulfate, and Fenton’s chemistry
  • In Situ Chemical Reduction (ISCR) – for hexavalent chromium and other contaminants (vadose and saturated zone)
  • Permeable Reactive Zones (PRZs) – design, construction, and optimization
  • Pump and Treat – design, construction, operations, and optimization
  • DNAPL Investigation and Remediation
  • Landfill CAP – design, permitting, and construction
  • Sediment Remediation – design, regulatory approval, and implementation
  • Remediation of Recalcitrants – MtBE, perchlorate, 1,4-dioxane, and 1,2,3-trichloropropane
  • Bench-scale and Field Pilot Test Design and Implementation
  • Remediation System Optimization (of existing systems)
