Our Process

Loureiro uses a methodical approach for our site evaluations. These evaluations are often aided by our state of the art treatability laboratory, confirming that the optimal remediation design has been selected for each site.

Treatability Studies

Loureiro performs treatability testing and microcosm studies to evaluate the site specific feasibility and to develop field-scale design parameters for all common in situ remediation technologies:

  • In Situ Chemical Oxidation:
    • Catalyzed Hydrogen Peroxide
    • Activated Persulfate
    • Permanganate
  • In Situ Bioremediation
    • Aerobic
    • Anaerobic
    • Biostimulation
    • Bioaugmentation
  • In Situ Chemical Reduction:
    • Zero Valent Iron (ZVI)
    • Bi-Metallic Particles
    • Metal Sulfides
  • In Situ Metals Stabilization
    • pH adjustment
    • metals sorption
    • metals precipitation
    • metals co-precipitation
