    Time domain electromagnetic surveys for assisting in determining the groundwater resources on Kaonoulu Ranch, LLP, property, Island of Maui, Hawaii
    (Blackhawk Geosciences, Inc., 2009-07) Nance, Tom
    "This report contains the procedures and results of surface Time Domain Electromagnetic (TDEM) geophysical surveys performed for groundwater resource evaluation on portions of Kaonoulu Ranch, LLP (Kaonoulu Ranch) property in the Makawao District, Island of Maui. Zapata Incorporated, Blackhawk Division (ZAPATA/Blackhawk) conducted the surveys from June 16 through June 18, 2009 for Kaonoulu Ranch, LLP located in the town of Kula, Maui. The main objective of the TDEM surveys was to explore for basal and high-level groundwater occurrences on the Kaonoulu Ranch property. The surveys were conducted at four TDEM sites to help determine the location for a future groundwater well on the property. 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, the 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 well placement and well completion depths."

    Time domain electromagnetic surveys for assisting in determining the groundwater resources on Kula 1800 property, Island of Maui, Hawaii
    (Blackhawk Geosciences, Inc., 2006-05) Nance, Tom
    This report contains the results of surface Time Domain Electromagnetic (TDEM) geophysical surveys performed for groundwater resource evaluation at the Kula 1800 Property located on the Island of Maui, Hawaii. Blackhawk, a Division of ZAPATA ENGINEERING (Blackhawk) conducted the surveys from May 2 through May 5, 2006 for Kula 1800 Investment Partners, LLC (Kula 1800 Partners) of Maui and Tom Nance Water Resource Engineering (TNWRE) of Honolulu, Hawaii. The main objectives of the TDEM surveys on Maui were to explore for possible basal and high-level groundwater occurrences at the project site. The surveys were conducted at six TDEM sounding locations. This allowed fot the creation of two survey lines, one positioned along the Pulehu Road and the second located along the Naalae Road near the Waiakoa Gulch. 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, the 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 well placement and well completion depths.

    Time domain electromagnetic surveys for assisting in determining the groundwater resources on Haleakala Ranch property, Island of Maui, Hawaii
    (Blackhawk Geosciences, Inc., 2003-07-02) Nance, Tom
    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.

    Geophysical surveys for assisting in determining the ground water resources near Kailua, north coast, Island of Maui, Hawaii
    (Blackhawk Geosciences, Inc., 1998-06-22) Nance, Tom
    The main objective of the geophysical survey was to assist in characterizing the hydrologic regime in the study area for a proposed ground water well. Ground water resources can occur on the Island of Maui basically in two modes: • In a basal mode where a lens of fresh water floats on saline water, and o In a high-level mode where the ground water occurrence is controlled by subsurface damming structures. From the results of the TDEM survey, a relatively thick basal fresh/brackish water resource is inferred. The lens of fresh/brackish water is expected to be about 200 ft thick under the area surveyed.
