Radiocolloids are a major factor in the rapid migration of radioactive
waste in groundwater. For at least two Los Alamos National Laboratory
(LANL) sites, researchers have shown that groundwater colloidal parti
cles were responsible for the rapid transport of radioactive waste mat
erial in groundwater. On an international scale, a review of reported
field observations, laboratory column studies, and carefully collected
field samples provides compelling evidence that colloidal particles e
nhance both radioactive and toxic waste migration. The objective of th
is project is to understand and predict colloid-contaminant migration
through fundamental mathematical models, water sampling, and laborator
y experiments and use this information to develop an effective and sci
entifically based colloid immobilization strategy. The article focuses
on solving the suspected radiocolloid transport problems at LANL's Mo
rtandad Canyon site.
