Impact/Purpose:
Provide awareness level training for RCRA project manages of monitored natural attenuation and groundwater modeling at RCRA sites.
Description:
The Groundwater Technical Support Center (GWTSC) is presenting a training course on the basics of monitored natural attenuation (MNA) and groundwater modeling applications at RCRA sites. MNA involves the reduction of contaminant concentrations to levels protective of human health and the environment within a reasonable time frame by physical, chemical, and biological processes including biodegradation, dispersion, dilution, sorption and volatilization. MNA does not mean monitoring with no action. Groundwater models are tools that allow the integration of site characterization data to predict the fate and transport of contaminants that may allow decision makers to evaluate differing remediation options. Groundwater modeling results are only as good as the data and assumptions used to the models.
