WRD Approves Groundwater Replenishment Assessment
The Water Replenishment District of Southern California (WRD) approved its Replenishment Assessment (RA) of $268.00 for 2013-2014 at a public hearing on May 10, 2013 after having nearly a dozen budget workshops to ensure that stakeholders understood the details of the RA. The funds generated from the RA cover the cost of water purchased to replenish the two largest and most utilized ...

Future groundwater supplies are a concern for growing Illinois communities
Population growth may be an economic boon for communities and counties, but the subsequent increased water demand could threaten the amount and quality of public water supplies available within the next few decades, according to Scott Meyer, hydrogeologist at the Illinois State Water Survey, a division of the Institute of Natural Resource Sustainability at the University of Illinois. In fact, ...

Groundwater Resources Generally Abundant in Coastal Carolinas
Large volumes of high quality groundwater fill aquifers along the Atlantic Coastal Plain (ACP) in North and South Carolina. Groundwater levels in much of the region remain relatively unchanged from predevelopment days, despite declines in some locations from large-scale pumping. These are among the key findings of a major federal study, conducted by the U.S. Geological Survey, to assess the ...

Groundwater availability detailed in California`s Central Valley
A new, three-dimensional water-modeling tool provides a detailed picture of how water flows below ground and how it relates to surface-water in rivers and canals in California’s Central Valley. The Central Valley Hydrologic Model, developed by scientists at the U.S. Geological Survey, is available for use by water managers and other agencies. The model was designed to help resource agencies ...

California water supplies not looking good for 2016
Public water agencies that serve millions of residents in drought-weary California might only receive 10 percent of expected supplies in 2016 - half the amount that flowed to them this year through the state's massive system of reservoirs and canals, state officials say. However, the early estimate could change, depending on the rain and snow that falls this winter, the state's Department of ...

USGS Groundwater Model: New Tool for Communities in Northern and Central Arizona
A new groundwater model of the interconnected aquifers in central and northern Arizona was released today by the U.S. Geological Survey, following a multi-year development effort that involved the Arizona Department of Water Resources and regional cooperators. The computer model, known as the “Northern Arizona Regional Groundwater-Flow Model,” simulates how recharge from rainfall ...

Human intervention in water levels has greater impact on river deltas than sea level rise
The rise in the sea level is not discernible in trends of extreme water levels, so a study by Wageningen University, Utrecht University and Nanjing University reveals. When it comes to extreme water levels in the Dutch delta, the effects of sea level rise were found to be negligible compared to the impact of human interventions. Worldwide, river deltas are exposed to a rise in sea level and ...

Sustainable management of water in an arid region: water supply measures compared
Water shortages in water stressed regions can be alleviated by building large infrastructures, such as water transfer systems or saltwater desalination plants, which increase the supply of water. However, a new study, which compares the environmental impact of water supply alternatives in a region of Spain, concludes that reducing water use, rather than increasing supplies, is a more sustainable ...
