The Hydraulic Profiling Tool (HPT) allows the user to create fast, continuous real-time profiles of soil hydraulic properties in both fine- and coarse-grained material. The HPT uses a sensitive, downlole transducer to measure the pressure response of the soil to injection of water. One primary use of this tool is to locate and define preferential migration pathways for contaminants in the subsurface. It can also be used to target zones for injection of remediation material. In addition, the HPT can be used to select well screen intervals, evaluate locations to conduct slug tests, and measure static water conditions across a site.
