As with inorganic colloids, most research on biocolloid mobility has been done on saturated transport, with little known about transport in unsaturated soils.
As for biocolloids, it has long been known that pathogenic microorganisms could move through soil to some extent, as evidenced by the required separation distances between septic systems and groundwater wells.
As such, there is a perceived need to better understand the factors that control the mobility of biocolloids in soil.

Science at Swinburne University, Dr Greg Lonergan, says composting cycles and earthworms are used to test the CRC products.
iron (Fe), aluminium (Al), manganese (Mn), or silicon (Si) hydro-oxides, carbonates, phosphates), and biocolloids
including viruses, bacteria, and protozoans (Buffte et al.
They cover phenomena at the micro, nano, and atto-scales, and techniques, theory, and supporting data, and detail recent concepts in the physics and chemistry of interfaces of rigid and deformable particles in homo- and heteroaggregate dispersed systems like emulsions, dispersoids, suspensions, nanopowders, foams, fluosols, polymer membranes, biocolloids
, and plasmas, and the hydrodynamic, electrodynamic, and thermodynamic instabilities that occur at interfaces.
In this work, we focus only on inorganic colloids, even though biocolloids
and organic matter may deserve equal attention.
Living organisms are complex heterogeneous systems in which biocolloids
and physicochemical reactions play the leading role.
Further extrapolation reveals that iron in the bow section, assuming 20,000 tons of iron, and that the rusticles were removing the iron at a constant rate, could be totally exported into the environment as red dust and biocolloids in approximately 280 to 420 years.
On both the 1996 and 1 998 expeditions, there were periods when the "sea snow", a mixture of biocolloids and zooplankton, was so intense that it resembled a blizzard on the prairies.
