Question

The permeability of a soil sample will be if entrapped air is present in the sample

Answer 1

Soil is an essential and largely non-renewable resource. The importance of its protection is internationally recognized. Because the introduction of contaminants into the soil results in damage or loss of its functions and possibly cross contamination of water with negative consequences for the food chain and human health, it is necessary to control contamination levels in soil and sludge from urban and industrial wastewater treatment.
