Natural Attenuation

Analytical testing dots Natural Attenuation

Natural attenuation, also referred to as intrinsic remediation, has been accepted as a feasible cleanup alternative for sites contaminated with petroleum hydrocarbons and other chemicals. Remediation by natural attenuation relies on the physical, chemical and biological processes that contribute to the decrease of both the contaminant concentration and plume size. Natural attenuation involves the use of the indigenous microorganisms at polluted sites to detoxify and degrade environmental contaminants through their physiological and metabolic capabilities.

Analytical testing dots

Natural attenuation processes include the following:

  • Biodegradation
  • Dilution
  • Dispersion
  • Sorption
  • Abiotic (related to nonliving elements such as climate, soil and water reactions)
