Document Summary

Consider the different terms on the safety factor we will come back to this. Water can infiltrate into the ground (called groundwater) Can decrease slope stability by adding extra weight and creating pore pressure that creates uplift. Water can move underground and carry toxic chemicals. Forms a leachate plume (mass of potentially contaminated water moving underground) Problem: garbage gets stored in an open-pit mine that has been abandoned. Need to determine where the potentially toxic leachate is going to go. Ex: sand soil is very porous, whereas clay soil is not. Permeability is the ease at which water can flow through the material (high permeability occurs if the pores are connected to eachother) Yes, water can flow through solid rock, as long as the empty spaces are connected (pores, cracks, etc) Sandstone has both high porosity and high permeability. Oil is often found in sandstone; doesn"t always have to be water.
