Groundwater From Wikipedia, the free encyclopedia Jump to: navigation search Groundwater is water located beneath the ground surface in soil pore spaces and in the fractures of lithologic formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become fully saturated with water is called the water table . Groundwater is recharged from, and eventually flows to, the surface naturally; natural discharge often occurs at springs and seeps , streams and can form oases or wetlands . Groundwater is also often withdrawn for agricultural municipal and industrial use by constructing and operating extraction wells . The study of the distribution and movement of groundwater is hydrogeology , also called groundwater hydrology Typically groundwater is thought of as liquid water flowing through shallow aquifers, but technically it can also include soil moisture permafrost (frozen soil), immobile water in very low permeability bedrock, and deep geothermal or oil formation water. Groundwater is hypothesized to provide

Groundwater water that has penetrated the earth's surface Animation by: Bramer Groundwater is all the water that has penetrated the earth's surface and is found in one of two soil layers. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water. The water table is the boundary between these two layers. As the amount of groundwater water increases or decreases, the water table rises or falls accordingly. When the entire area below the ground is saturated, flooding occurs because all subsequent precipitation is forced to remain on the surface. The amount of water that can be held in the soil is called "porosity". The rate at which water flows through the soil is its "permeability". Different surfaces hold different amounts of water and absorb water at different rates. Surface permeability is extremely important for hydrologists to monitor because as a surface becomes less permeable, an increasing amount of water remains on the surface, creating a greater potential for flooding . Flooding is very common during winter and early spring because the frozen ground has no permeability, causing most rainwater and meltwater to become

References Purpose of this Bulletin The land surface was traditionally considered to be sufficient to protect the quality of underlying groundwater. It is now recognized that natural soil processes that change contaminants into harmless substances are often overwhelmed by waste products from human activities. Groundwater protection programs require an understanding of the groundwater resource. The purpose of this bulletin is to help the reader become more knowledgeable about groundwater and the terminology commonly used to describe it. A pictorial approach is used to enable the reader to quickly grasp basic groundwater terms and concepts. The information contained in this bulletin should help local government officials and citizens become informed and able to make decisions on how to protect and manage community groundwater resources.

By law, every new well in the state that diverts ground water must have a well permit. To obtain a permit, a person must file an application for approval of a permit with the State Engineer (see Forms ). Over 10,000 applications are submitted for review annually and the staff of the State Engineer evalutes the applications under strict statutory guidelines. The division, in cooperation with various local ground water management districts, operates a statewide network for monitoring ground water levels. Over 1,500 wells are measured to assist in projecting ground water levels and to aid in the administration of ground water. This information is available through the water level measurement reports (monitoring reports) issued each year (see reports in Documents and Records Notice!!

A-Z List Site Map Contact the DNR What's New? ... Water Ground water Ground water is the water beneath the land surface that fills the spaces in rock and sediment. It is replenished by precipitation. Under natural conditions much of that recharge returns to the atmosphere by evapotranspiration from plants and trees or discharges to surface waters. Ground water discharge to surface waters allows streams to flow beyond rain and snowmelt periods and sustains lake levels during dry spells. Ground water occurs everywhere in Minnesota, but the availability of ground water for water supplies vary throughout the state. Availability for larger withdrawals may be limited in some areas. Ground water supplies about 75 percent of Minnesota's drinking water and nearly 90 percent of the water used for agricultural irrigation.

Ground Water in Florida Highlights Sources of high quality ground water underlie virtually all of Florida. Ninety percent of this state's population relies on these ground water resources for their drinking water. Additionally, over 50% of all other water needs including agricultural, industry, mining, and electric power generation are supplied by ground water resources. Ground water also serves as the source for Florida’s many springs and provides a significant input to many of Florida’s lakes and rivers. In DEP, responsibility for ground water is divided into two individual programs – ground water protection and ground water regulatory. The Ground Water Protection Program is responsible for conducting programs and activities that assess and protect the state’s ground water resources, integrating ground water protection activities into Florida’s watershed program. Activities include conducting basin-scale and detailed ground water evaluations and assessments, development of ground water-surface water interaction assessment tools, management of the USEPA Section 106 ground water grant, management of research and monitoring projects under Florida’s Springs Initiative, oversight of agricultural best management practice ground water monitoring studies, and participation in evaluations of new pesticides that have potential ground water impacts.
