[Scientist] W W Wood [Research Area] Dispersion of Toxic and Radioactive Wastes in Ground-Water Systems show details View Publications [Science Topics] Groundwater Flow and Transport; Radioisotopes; Solute Transport; Unsaturated Zone [Last Name] Wood [Details] 
Movement of toxic and radioactive substances in aquifer systems occurs in all three phases and is controlled by both hydrologic and chemical forces. Solute movement can be greatly affected not only by physical dispersion, but by other factors such as exchange sorption, chemical kinetics, and ionic distributions. Movement of gases and particulate material in the unsaturated zone are controlled by many additional factors. Knowledge of how these physical and geochemical factors affect prediction of movement of toxic and radioactive wastes is only generally known for ideal systems. This project's objective is to develop field methods and techniques that will yield values for physical and geochemical factors of regional significance in a ground-water system.
