Home RWA Contact Us To manage, protect and sustain the groundwater resources of the basin in Sacramento County north of the American River consistent with the Water Forum Agreement for the benefit of the water users within the basin, and to coordinate with other water management entities and activities throughout the region. Groundwater Management Plan SGA adopted its Groundwater Management Plan on December 11, 2003. The plan is an essential tool for ensuring the viability of the groundwater resource while supporting the objectives of the Sacramento Water Forum Agreement. Banking and Exchange Pilot Studies SGA members participated in two pilot studies to bank and exchange water to demonstrate the viability of conjunctive use opportunities within the basin. SGA Accomplishments 2003 was a year of tremendous progress for both the Sacramento Groundwater Authority and Regional Water Authority.

Security and Privacy Notices Program Management Completion Strategy Integrated Fieldwork ... Groundwater/Vadose Zone Integration Project Documents Groundwater at the Hanford Site In general, groundwater is a supply of fresh water found in layers beneath the earth's surface. Because groundwater can be a source of drinking water, contamination is a concern. Contamination can occur from agricultural and industrial activities. At Hanford, past industrial activities have impacted the groundwater. Fifty years of nuclear weapons production resulted in approximately 1.7 trillion liters (450 billion gallons) of liquid waste being released to the ground at the Hanford Site. Some of the associated contaminants have reached the groundwater. Hazardous chemical contaminants include carbon tetrachloride, chromium, and nitrates. Radioactive contaminants include iodine-129, strontium-90, technetium-99, tritium, and uranium. Commonly sought Hanford Environmental Information System (HEIS) well-monitoring data , tracking contaminants from about 1950 to the present, can be accessed via a user-friendly web-based tool.

67. Illinois Groundwater Consortium Working toward providing a scientifically valid basis for agricultural chemical management and regulatory decisions affecting groundwater. http://www.siu.edu/worda/igc/

About the IGC The Illinois Groundwater Consortium (IGC) was established in 1990 to investigate the short- and long-term effects of agricultural chemical contamination on groundwater, the environment, and, ultimately, human health and welfare. IGC members—the Illinois State Geological Survey , the Illinois State Water Survey Southern Illinois University Carbondale Southern Illinois University Edwardsville , the University of Illinois Agricultural Experiment Station, and the University of Illinois Cooperative Extension Service —worked toward providing a scientifically valid basis for agricultural management and regulatory decisions affecting groundwater. The IGC was funded by Congressional appropriations through the U.S. Department of Agriculture and administered by SIUC's Office of Research Development and Administration Funding for the consortium ended with the 2003 fiscal year. This web site is still being maintained in abbreviated form to allow access to IGC research findings. Research Emphases The IGC began its work with basic research studies on groundwater, particularly groundwater contamination and the effects of flooding on groundwater and surface water in Illinois. In its later years of operation, the consortium emphasized the relationship between land use practices, particularly urban and industrial growth, and water quality and quantity. The IGC funded grants on a competitive basis from proposals submitted by consortium members. A research/planning conference held each year in April brought together researchers, government agency personnel, and other interested parties to discuss IGC research findings and to chart future directions for the consortium.

74. Ground Water Fact Sheet The top of the water in the soil, sand, or rocks is called the water table and the water that fills the empty spaces and cracks is called ground water. http://pubs.usgs.gov/fs/OFR93-643/

WHAT IS GROUND WATER? How does water get into the ground? When rain falls to the ground, the water does not stop moving. Some of it flows along the land surface to streams or lakes, some is used by plants, some evaporates and returns to the atmosphere, and some seeps into the ground. Water seeps into the ground much like a glass of water poured onto a pile of sand. As water seeps into the ground, some of it clings to particles of soil or to roots of plants just below the land surface. This moisture provides plants with the water they need to grow. Water not used by plants moves deeper into the ground. The water moves downward through empty spaces or cracks in the soil, sand, or rocks until it reaches a layer of rock through which water cannot easily move. The water then fills the empty spaces and cracks above that layer. The top of the water in the soil, sand, or rocks is called the water table and the water that fills the empty spaces and cracks is called ground water Water seeping down from the land surface adds to the ground water and is called recharge water. Ground water is recharged from rain water and snowmelt or from water that leaks through the bottom of some lakes and rivers. Ground water also can be recharged when watersupply systems (pipelines and canals) leak and when crops are irrigated with more water than the plants can use.
