In situ remediation is used to treat numerous contaminants in soil and groundwater through the application of reagents and physio-chemical processes in the subsurface. The performance and effectiveness of in situ remediation technologies are assessed through monitoring of groundwater and other media. Often, monitoring programs are established based on existing well networks and industry rules of thumb. Development of monitoring programs needs to account for the type, scale, and longevity of the applied in situ remediation technology, as well as the conceptual site model. The objectives of this course are to review the effects that different in situ remediation technologies have on soil and groundwater and best practices for monitoring those effects.
The first part of this course will include a review of in situ remediation technologies and their physio-chemical effects on groundwater systems. The course will then present the concept of a zone of influence for in situ remediation, the influence of the conceptual site model on the zone of influence, and how groundwater geochemical conditions stabilize following an in situ remedy application. Then, design considerations for in situ remediation monitoring programs will be discussed. Several case studies will be presented to illustrate design concepts. Lastly, regulatory requirements for the monitoring of in situ remediation in Connecticut will be reviewed and related back to the design of monitoring programs.
Course participants will learn how to design monitoring programs for in situ remediation that provide an adequate level of information to understand the effectiveness of the remedy, while providing the ability to address uncertainties of the subsurface. They will learn about the different stages and objectives of monitoring. Further, they will gain an understanding of the range of biogeochemical and physical effects that can occur during implementation of an in situ remedy. Design concepts will be reviewed. Participants will be provided with a framework for selection of design parameters.
