This paper attempts to introduce the work described in this special section on colloid transport
within a more general perspective of the evolution of our understanding of the importance …

A field tracer experiment was conducted in a lateral flow field in the weathered and highly
fractured upper 6 m of a 40‐m‐thick clay‐rich till plain in southwestern Ontario. In the upper 3 …

Field values of horizontal hydraulic conductivity measured in the upper 1.5–5.5 m of a
weathered and fractured clay‐rich till were strongly influenced by smearing around piezometer …

Groundwater is routinely analyzed for fecal indicators but direct comparisons of fecal indicators
to the presence of bacterial and viral pathogens are rare. This study was conducted in …

Box counting is widely used for characterizing fracture networks as fractals and estimating
their fractal dimensions (D). If this analysis yields a power law distribution given by N ∝ r −D , …

The health risks of As exposure due to the installation of millions of shallow tubewells in the
Bengal Basin are known, but fecal contamination of shallow aquifers has not systematically …

A majority of households in Bangladesh rely on pond water for hygiene. Exposure to pond
water fecal contamination could therefore still contribute to diarrheal disease despite the …

Experiments in an undisturbed, saturated column of weathered and fractured shale saprolite
using fluorescent carboxylate-coated latex microspheres as tracers indicate that particle …

Two bacteriophages, MS-2 and PRD-1, were added to water to an initial concentration of
105-106 pfu mL-1 in a trench-to-trench lateral groundwater flow and tracer migration …

Eight saturated column experiments were conducted to examine the effects of solution
chemistry and grain size on the transport of colloids through crushed silica sand. Two sizes of …
