Factors The stability of a slope can be described as two forces working against one another. Driving forces work to cause slope materials to move downslope, whereas resisting forces act to keep the materials on the slope. When the ratio of resisting forces to driving forces (called the factor of safety) is greater than 1, the slope is stable. When it is less than 1, the slope usually fails. Water and Vegetation. Water can increase the driving forces and reduce the resisting forces. Saturation from rainfall can increase the slope mass, 15 Landslides thereby increasing the driving forces.

In the United States, federal standards to protect groundwater quality were implemented in 1991 and required some landfills to use plastic liners and collect and treat leachate. However, many disposal sites were either exempted from these rules or grandfathered (excused from the rules owing to previous usage). Although the federal rules marked a significant improvement in the management of solid waste, some think that these rules do not go far enough. There is an increasing belief among solid waste experts that unless further steps are taken to detoxify landfilled materials, today’s society will be placing a burden on upcoming generations to address future landfill impacts.
