Abstract:"This report contains the procedures and results of surface Time Domain Electromagnetic (TDEM) geophysical surveys performed for groundwater resource evaluation on property located in the Lahaina District, above the town of Kaanapali, Maui. The property included land owned by West Maui Land Company, Inc (WMLCI) and Kaanapali Land Management Corporation (KLMC). Zapata Incorporated, Blackhawk Division (ZAPATA/Blackhawk) performed the surveys for Belt Collins Hawaii Ltd (BCHL) and Tom Nance Water Resource Engineering (TNWRE) from October 20 through October 26, 2009. The project is known as
Villages of Leiali’i and was accomplished for the Hawaii Housing Finance and Development Corporation (HHFDC) located in Honolulu, Hawaii.
The main objective of the TDEM surveys was to explore for basal and high-level groundwater occurrences on the property. The surveys were conducted at six TDEM sites to help determine the location for a future groundwater well.
TDEM is a geophysical method that determines from TDEM is a geophysical method that determines from the surface the geoelectric section (resistivity layering) of the subsurface. From the geoelectric section, information about geology and water quality can be inferred. This is possible because the electrical resistivity of the earth depends on lithology, porosity, degree of saturation, and concentration of dissolved solids in the groundwater. Geophysical surveys, combined with other hydrogeologic information, are used to provide optimum locations for water well placement and well completion depths."
