Monitored Natural Attenuation (MNA) is often a preferred option relative to active in situ remediation as it is:

• Less invasive, especially for site with existing activities or obstructions
• Uses existing subsurface processes such as biological/abiotic degradation, dispersion, dilution, and retardation to reduce risk.
• Relatively lower in cost when compared to other remedial technologies

XDD has been providing MNA evaluation and sampling services throughout our history, those services include:

• Conceptual model refinement
• Evaluation of fate and transport within groundwater and vapor phases
• Timeframe estimates relative to source zone properties
• Evaluation of existing MNA pathways, such as:
  • Dispersion
  • Dilution
  • Abiotic and biotic transformations
  • Retardation
• Site investigations and analyses to determine the magnitude of MNA processes
