Abstract

When water percolates through soil, interactions between chemicals in the water and components of the soil take place. Adsorption and chemical precipitation can remove chemicals from the water, on the other hand some chemicals in the water may solubilize or exchange with substances from the soil.

A review of the physical, chemical and biological interactions between percolating water and soil is presented.

Two case studies on artificial recharge of groundwater, based on work carried out at Murdoch University, are discussed: one involves stream water, another involves secondary treated waste water. In the first case turbidity and colour are removed by mechanical straining action of the soil. In the second case the removal of nitrogen from the treated waste water is achieved by a series of physical, chemical and microbiological processes with alternate flooding and drying of the soil.
