3D Ground-water to surface-water flow system: The three dimensional (3D) image shows ground-water flow from an upland to an adjacent stream. The image is a 3D representation of the two dimensional (2D) ground-water flow nets presented in the 1983 Ralph C Heath U.S. Geological Survey Water-Supply Paper 2220 Basic Ground-Water Hydrology. Ground-water and surface-water elevations are contoured in three dimensions using Environmental Visualization System software. The ground-water elevations are treated as pressure values obtained from the mid point of the well screens. The upper, transparent surface shows the 3D water-table contour map. The colored surfaces are iso-pressure surfaces and are the 3D equivalent of the iso-pressure lines on the contour map.

3D Ground-water and surface-water samples: The three-dimensional (3-D) visualization shows sample locations and benzene concentrations at an industrial facility and adjacent limestone quarry. The aerial photograph is faded to show the subsurface samples. Samples are shown as spheres. Two (2) stream samples were collected upstream and downstream of the facility, three (3) ground-water samples were collected from monitoring wells downgradient of the facility, and from two (2) seep samples were collected from the southern quarry wall.

The color of the sphere represents benzene concentration. The colors range from blue (less than laboratory detection limits of 0.5 parts per billion (ppb)) up to red (10 ppb). No benzene was detected in the stream and quarry samples while low benzene concentrations were detected in the ground-water samples. Only one (1) ground-water sample had a concentration greater than the RISC residential closure level of five (5) ppb.

This is a 3-D visualization of a geothermal system in Bloomington, Indiana. The YouTube video shows the vertical geothermal ground loop and underlying geology at the IU Office of Sustainability EHouse located at East 10th Street.

Let's use this continuous, widely-distributed, renewable energy to provide for our energy needs.
This 3-D visualization shows the distribution of tetrachloroethylene dissolved in ground water at an environmental investigation site. This chemical has several synonyms such as perchloroethylene, perc, and PCE. PCE is a liquid used in dry cleaning and degreasing. The spheres show the positions of the ground-water samples and the color of the spheres shows the relative PCE concentrations (i.e., warmer colors equal higher concentrations). The gray and blue columns show the position of the monitoring wells with the blue column being the screened interval of the well. The dissolved PCE plume is shown with transparent shells encompassing samples with concentrations greater than 10,000 micrograms per liter (ug/L) at the concentrated portion of the plume and greater than 200 ug/L in the more dilute and downgradient portions of the plume. (PS - This visualization was entered in an Instructables Scientific Visualization contest; Instructables is an engaging Maker website.)
