WebVolumetric water content, θ, is defined mathematically as: where is the volume of water and is equal to the total volume of the wet material, i.e. of the sum of the volume of solid host material (e.g., soil particles, vegetation tissue) , of water , and of air . Gravimetric water content [1] is expressed by mass (weight) as follows: WebGravimetric methods may be used to quantify TPHs from water samples if the components of interest are non-volatile. The water is extracted with a solvent (eg, hexane), the solvent extract is passed through a florisil column to remove biogenic interferences, and the eluate is evaporated, dried at 105°C, and weighed.
