3.1 Utilizing Horizontal Directionally Drilled Wells for a Variety of Remediation Applications
Moderator: Brian Jeffers, Geo Lab Drilling; Presenter(s): Brian Shinall, Ellingson-DTD; Kyle Carlton, Geosyntec; Craig Divine, ArcadisRoom 1/2
Application of cutting-edge technologies associated with Horizontal Directional Drilling (HDD) requires a basic understanding of the various methodologies available, their physical capabilities and limitations, and the numerous considerations to be given for their selection as a site remediation strategy. This session will discuss these concepts and highlight case studies showing the benefits of HDD technologies for large-scale and small-scale remediation efforts. A case study will be presented showcasing the utilization of HDD wells for hydraulic control and freshwater injection beneath Coal Combustion Residual (CCR) ponds, and an in-depth look at the The Horizontal Reactive Treatment Well (HRX Well) for In-Situ cVOC and PFAS mass flux/discharge reduction will be presented.
