Description:
Among the alternatives considered for the remediation of soil and ground water at hazardous wastes sites are the use of natural processes to reduce or remove the contaminants of concern. Under favorable conditions, the use of natural attenuation can result in significant cost savings and compensate for uncertainties encountered in complex subsurface settings. While chemical transformation, dispersion, dilution, sorption, and volatilization are discussed, aerobic and anaerobic degradation comprise the major processes for the reduction of contaminant mass in the subsurface. The mechanisms of natural attenuation are examined along with monitoring requirements, data analysis, rates of degradation, and mathematical modeling. Natural attenuation is also referred to as assimilative capacity, intrinsic remediation, and passive remediation.
