Comparison of Predicted and Observed Plume Trends at Fuel and Solvent Contaminated Sites
Abstract
Subsequent to the initial natural attenuation treatability studies performed from 1994 through 1999 at over 45 sites, update data collected by the National Risk Management Research Laboratory and Base monitoring programs were used to evaluate the correctiveness or natural attenuation at reducing contaminant concentrations in groundwater at 24 selected sites. Discrepancies between observed and predicted contaminant trends and plume behavior suggested that critical model input parameters may be inaccurate; therefore, the influence or natural attenuation processes may not have been accurately simulated. As a result of these observations, this project was initiated to compare model-predicted and observed contaminant trends and to evaluate some fundamental parameters that impact the accuracy of natural attenuation predictions, relative to updated field observations.
