19. In Situ Remediation Injections INJECTIONS Traditional remediation product injections in the environmental industry focus extensively on chemistry and biology, and the physical distribution of the agent in the aquifer has not received as much attention. For many remediation products, effective distribution or contact with the contaminant mass is crucial to successful remedial injection. Additionally, injected products often migrate to the surface adjacent to the injection rod string (blow-by), which substantially decreases remedial efficacy. The historical thought process was that the zones of higher hydraulic conductivity would most likely also contain the larger contaminant mass. It was assumed that these zones of higher conductivity would receive the majority of the injected remediation product. However, practical experience indicates that this theory of hydraulic conductivity and injected product acceptance may not be uniformly applicable across contaminated sites.

21. INJECTIONS What is the Hornet Tool? The Hornet Tool is an injection technology that potentially improves the performance of other remedial approaches, such as pump-and-treat systems and the injection of in-situ remediation products into an aquifer . The tool is designed as a surface-mounted system for direct push rods (or injection wells). The tool generates a fluid pressure pulse through the injected product that causes momentary elastic flexure of the pore structure. The pressure pulse moves fluid into (and out of) a larger number of pore networks, with the goal of obtaining a more uniform injection front, and potentially decreasing the blow-by effect.
