1. Specific pore waters , can cause the further precipitation of carbonate or silica cements. 2. Additionally, the pore water of sediments can be collected by centrifugation and tested without extraction. 3. The concept of effective stress truly becomes interesting when dealing with non-hydrostatic pore water pressure. 4. The pore water pressure is essential in differentiating a soil's total stress from its effective stress. 5. Pore water pressure is the pressure of water that is trapped within the particles of rocks and soils.6. Alternatively, shear strength may be decreased by weathering, changes in pore water pressure, and organic material. 7. Salt is also bound within the matrix of the sediments, generally in pore waters , trapped during deposition. 8. When ice growth induces stresses in the pore water that breaks the rock, the result is called hydrofracture. 9. Normally, effective normal stress is calculated by subtracting the pore water pressure from the normal stress, in natural conditions. 10. Because the archaea and bacteria metabolize and release bubbles within the tailings, the pore water can go through the soil easily.
