COURSE DESCRIPTION

Remediation by natural attenuation (RNA) relies on the physical, chemical and biological processes that contribute to decrease both contaminant concentration and plume size. Extensive analysis of these intrinsically occurring processes is required to assess the time required for cleanup and the extent of future migration of the contaminant plume. Natural attenuation processes include biodegradation, dilution, dispersion, sorption, and abiotic reactions. The large number of contaminated sites across the United States and great costs of most other remediation procedures as well as the lack of efficient remediation technologies for some of these sites make intrinsic remediation an attractive option when its use can be justified.

Natural attenuation, as any other remediation option, requires an assessment of its appropriateness based on the risks, site characteristics, and the potential to achieve remediation goals in a case-by-case basis. This short course is designed to provide a hands-on working knowledge of such an assessment with emphasis on the ASTM Remediation of Groundwater by Natural Attenuation at Petroleum Release Sites Standard (E 1943-98). Participants will gain an understanding of the step-by-step procedures to be implemented in conducting an RNA assessment through the use of problem sets and case studies.

COURSE CERTIFICATION
