Description:
There is a need to develop and field-test integrated remediation technologies that operate in a synergistic manner for cost-effective treatment of contaminated sites to achieve risk-based and rational endpoints. Aggressive technologies designed for rapid source-zone remediation must be linked to technologies for achieving enhanced cleanup of the dissolved plume. Remediation technology integration should minimize the cost to achieve risk-based endpoints by selecting treatment trains or technology combinations that when coupled together work in a synergistic manner. Contaminant flux across a control plane immediately down-gradient from the source, rather than contaminant concentraion at a monitoring point, should be used as the basis for evaluating the effectiveness or success of remediation. The acceptable threshold contaminant flux should be set equal to or less than the natural attenuation capacity within the dissolved plume. Simulation results show that significant contaminant-flux reductions can be achieved by partial removal of contaminant mass from DNAPL source zones.
