Evaluation And Application Of Dye Tracing In A Karst Terrain, James William Scanlan

Masters Theses

"The purpose of this investigation was to select and evaluate in the laboratory a tracing method appropriate for use in karstic areas, and to perform field tracing studies in the south central Missouri area bounded by the cities of Rolla, St. James, and Salem in an attempt to establish existing direct flow connections between surface and subsurface waters. Fluorescein (sodium salt), Rhodamine WT, and Rhodamine B were evaluated as tracers in the laboratory and the first two dyes were employed in the field. After careful evaluation of a number of adsorbents, extracting solvents, and detection techniques, a method consisting of …
