Toxic Substances Hydrology Program
Natural Attenuation for Groundwater Remediation
On March 1, 2000, the National Research Council released a new report titled "Natural Attenuation for Groundwater Remediation". This is the final report of a committee commissioned in 1997 to assess current knowledge on cleanup of contaminated sites by natural processes, to define limitations of natural attenuation and steps needed to document its suitability at contaminated sites, and to evaluate the adequacy of existing protocols. USGS scientist Barbara Bekins was a member of the authoring committee, and results of USGS field research studies are referred to frequently in the report. The USGS Toxic Substances Hydrology Program was a cosponsor of this project.
