| The objective of this effort was to conduct a full-scale demonstration of the use of the high-resolution piezocone and GeoVIS to determine direction and rate of ground water flow in three dimensions. While the GeoVIS did not provide effective porosity values within the anticipated range, the high-resolution piezocone and resulting models fall within the quantitative tolerances set forth in this demonstration. Therefore, the sensor probe approach to determining hydrogeologic characteristics is deemed appropriate for the demonstration site characteristics. When compared to conventional approaches comprised of clustered well installations, aquifer tests, sample analyses, and three-dimensional and cross-sectional interpolations, cost savings for flux distribution determination using the high-resolution piezocone coupled with a membrane interface probe system exceeds 60 percent. |
