Partition coefficient can also be used to predict the mobility of radionuclides in groundwater. [35] In the field of hydrogeology, the octanol–water partition coefficient K ow is used to predict and model the migration of dissolved hydrophobic organic compounds in soil and groundwater.
Bioconcentration factors can also be related to the octanol-water partition coefficient, K ow. The octanol-water partition coefficient (K ow) is correlated with the potential for a chemical to bioaccumulate in organisms; the BCF can be predicted from log K ow, via computer programs based on structure activity relationship (SAR) [7] or through ...
The n-octanol-water partition coefficient, K ow is a partition coefficient for the two-phase system consisting of n-octanol and water. [1] K ow is also frequently referred to by the symbol P, especially in the English literature. It is also called n-octanol-water partition ratio. [2] [3] [4]
Thus, the freely dissolved interstitial water concentration of nonionic organic chemicals can be predicted using the K OC, the organic carbon-water partition coefficient, which is a constant for each chemical: K OC = C OC /C d. For nonionic organic contaminants, the K OC can be determined based on the octanol-water partition coefficient (K OW).

Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water. [2]
The Plastic Limit is the water content at which the soil behavior transitions from that of a plastic solid to a brittle solid. The Shrinkage Limit corresponds to a water content below which the soil will not shrink as it dries. The consistency of fine grained soil varies in proportional to the water content in a soil.
