Evaluation of the effectiveness of the M-Area extraction system
- Du Pont de Nemours (E.I.) and Co., Aiken, SC (United States)
The effect of the M-Area extraction system on groundwater flow patterns in the vicinity of the M-Area was investigated using the groundwater flow model of the A- and M-Areas developed by S. S. Papadopulos and Associates, Inc. The purpose of this investigation was to: (1) evaluate the performance of the extraction system, in terms of its capability to prevent migration of volatile organic chemicals from the M-Area, and (2) evaluate the length of time required to remove groundwater from the capture zones of the extraction wells. The effectiveness of the groundwater extraction system was evaluated by calculating where the groundwater that is pumped from the extraction system enters the groundwater table as recharge, and by calculating the flow paths and travel times for this groundwater from the recharge area to the extraction wells. If the groundwater flow paths to the extraction wells encompass the zones containing the chemicals of concern, the extraction system, if operated long enough, will prevent migration of the chemicals from the M-Area. The time required to reduce the concentrations of the chemicals of concern, the nature of the source of the chemicals, and the interaction of the chemicals with the groundwater environment. This investigation focused on the patterns of groundwater velocity created by the extraction systems, the zones of capture for the extraction wells, and the rate of groundwater evacuation from the capture zones.
