A hole dug or drilled by people to gain access to groundwater. The process of extracting groundwater where there is little to no groundwater recharge. A sediment or rock layer that lacks pores and cannot contain water. A horizontal zone within the soil identified by its chemical and physical properties. The available air space within sediments or rocks. The region of transition between the zone of aeration and the zone of saturation. The movement of water into an aquifer. The layer of the ground not permanently saturated with water. The process by which rainwater moves through the soil through narrow, meandering channels. A soil classification system that groups soils into 12 categories, or orders. A localized water table that lies above the regional water table. Withdrawal of water from an aquifer faster than the aquifer is recharged at the site of a well. The process by which rainwater carries soil particles downward. Water that entered an aquifer long ago and is no longer being replenished. The layer of the ground that is usually saturated with water. The ease with which water can flow through soil, sediments, or rocks. The process of soil formation. Soil that consists of approximately 40% sand, 40% silt, and 20% clay and has a high organic content. The cone- A well that has been drilled through an aquiclude into a confined aquifer below and may gush water. The process by which water seeps into the ground through the force of gravity. A sediment or rock layer with pores that contain water. The unseen water required to produce a manufactured item or food. The process by which rainwater carries dissolved nutrients downward. Water found beneath Earth’s surface in sediments and rocks. The cloud of pollution that migrates through an aquifer away from its source. The contamination of a well by salt water as a result of groundwater overdraft. The top surface of an aquifer’s zone of saturation. A naturally occurring discharge of groundwater that is pushed to the ground surface by hydraulic pressure. (pronounced HYOU- The elevation to which hydraulic pressure will push water in pipes or wells. Any loose, fragmented Earth material that covers bedrock. The layer of sediment that has been modified by organisms and water; the region of the lithosphere into which plant roots extend. The process of cleaning a contaminated aquifer. The amount of water required to produce a specific item, food, or service. Rock that is structurally part of and connected to Earth’s crust. A prolonged period of water shortage. |
