It is essential to understand the mechanisms that control virus and bacteria removal in the
subsurface environment to assess the risk of groundwater contamination with fecal …

A series of column experiments was undertaken to explore the influence of colloid input
concentration (2, 1, 0.5, and 0.25 times a reference concentration), colloid size (negatively …

Saturated soil column experiments were conducted to explore the influence of colloid size
and soil grain size distribution characteristics on the transport and fate of colloid particles in …

Colloids are potential vectors of contaminants in the subsurface environment. The
knowledge of transport and retention behaviors of colloids is of primary importance for …

This study theoretically and experimentally examined effects of surface roughness on
detachment of colloids deposited under favorable chemical conditions on reduction of …

Colloid transport experiments are often conducted in cleaned sand, and the results are then
projected onto mechanisms in natural porous media. We conducted tracer experiments to …

Filtration theory does not include the potential influence of pore structure on colloid removal
by straining. Conversely, previous research on straining has not considered the possible …

We present continuum models to describe colloid release in the subsurface during transient
physicochemical conditions. Our modeling approach relates the amount of colloid release to …

The role of humic acid in the transport of negatively charged colloids through porous media
was examined. Adsorption of humic acid on latex colloids and silica collectors reduced the …

Batch leaching tests are commonly used to assess the leaching potential of various organic
and inorganic contaminants from soil. The toxicity characteristic leaching procedure (TCLP) …
