Groundwater Flow and the Water Cycle. Yes, water below your feet is moving all the time, but not like rivers flowing below ground. It's more like water in a sponge. Gravity and pressure move water downward and sideways underground through spaces between rocks. Eventually it emerges back to the land surface, into rivers, and into the oceans to ...In 2007, about 390 million kilograms (430,000 tons) of pesticides, including herbicides, insecticides, and fungicides, were used in the United States. Pesticides released into the environment for agricultural and nonagricultural purposes can contaminate surface water and groundwater, which are critical sources of drinking water.A lack of these surface waters can have negative effects on ecosystems. Figure 12.1.1 12.1. 1: Bar chart of the distribution of Earth’s water, including total global water, fresh water, and surface water. Oceans are the largest of Earth’s water reservoirs, and only 2.5% of Earth's water is freshwater. Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table. Contrary to popular belief, groundwater does not form underground rivers. It fills the pores and fractures in underground materials such as sand, gravel, and other rock, much the same way that water fills a sponge.
