Advances in multi-disciplinary techniques for characterizing and monitoring long-term contaminant migration and attenuation in fractured rocks
Session ID#: 82908
Session Description:
Thousands of groundwater contamination sites in the US, many involving DNAPLs in bedrock aquifers, are unlikely to be restored within 50-100 years (NRC, 2013). Remediation techniques developed for unconsolidated sediments are generally unsuccessful in bedrock; however, diffusion’s strong influence on source zone fluxes and plume migration in rock makes monitored, natural attenuation a viable management option. Spatio-temporal variations in physical, chemical, and biological interactions hinder predicting the efficacy, and then monitoring, natural attenuation at impacted sites. Understanding the natural resiliency of these aquifers will facilitate the management of existing contaminated sites and the development of source water protection strategies where bedrock aquifers are threatened by resource extraction and waste disposal. We invite studies advancing novel lab, field, and modeling techniques for quantifying the processes controlling contaminant transport, fate, and attenuation in fractured rocks. Submissions aimed at reducing uncertainty in parameters and improving conceptual models for prediction are of particular interest.
