Solar-distilled plant water that has gone through various levels of laboratory preparation to remove constituents that can interfere with subsequent tritium analysis. A 2-gram solid-phase extraction column was necessary and sufficient for accurate determination of tritium concentrations in water from test plants (creosote bush, Larrea tridenatata) -- from the Detecting Tritium in Plants Photo Gallery


The Toxics Program supports the development of knowledge and methods for the collection, analysis, and interpretation of data related to fundamental questions about contamination in the hydrologic cycle. What is the significance of these activities in relation to the field investigations?
