dc.description.abstract This report contains the results of surface Time Domain Electromagnetic (TDEM) geophysical surveys performed for groundwater resource evaluation on the Island of Maui. Blackhawk GeoSciences (Blackhawk) conducted the surveys on June 16 and June 17, 2003, for Tom Nance Water Resources Engineering (TNWRE) and Betsill Brothers Construction (BBC). 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, because the electrical resistivity of the earth depends on lithology, porosity, and concentration of dissolved solids in the ground water. The general objective of the TDEM surveys on Maui was to explore for possible basal groundwater occurrences beneath the survey area. These TDEM surveys were conducted near the 600ft elevation level located above the High Technology Park on Haleakala Ranch property. Geophysical surveys, combined with other hydrogeologic information, are used to provide optimum locations for well placement and well completion depths.
