High quality groundwater sampling
Representative Samples A project manager’s goal for groundwater sampling is to collect samples that are representative of actual in-situ conditions, and to maintain sample integrity by minimizing the changes in sample quality and chemistry during collection. Sampling has evolved from earlier techniques of bailing and high rate pumping, to techniques of minimal drawdown and low flow pumping. ...

New Map Shows How Groundwater Pumping Could Affect the Malad River
A new report illustrates how groundwater pumping can affect the amount of water available in streams within the Malad-Lower Bear River Area in Utah. The product was developed by the U.S. Geological Survey, in cooperation with the Utah Department of Natural Resources, Division of Water Rights. “The information from this study will be used to aid the state engineer in making water-rights ...

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, ...

Impacts of groundwater on local rainfall under a changing climate
Climate change is expected to bring hotter conditions to many important agricultural regions. This will affect rates of evaporation from the ground and may also have an impact on local rainfall patterns. A recent study suggests that the depth of groundwater may determine the susceptibility of a region to drought following changes in temperature and rainfall. Understanding the transfer of water ...

EPA invites public comment on Chehalis area groundwater cleanup
The U.S. Environmental Protection Agency invites public comment on a draft plan to clean up contamination at the Hamilton-Labree Superfund site near North Hamilton and Labree Roads, south of Chehalis, Washington. EPA will hear comments on the cleanup plan at a public meeting on Tuesday, October 23, from 6:30 to 9:00 p.m. at the Veterans Memorial Museum, 100 SW Veterans Way, in Chehalis. EPA ...

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 ...

Study Assesses Threats to Groundwater Availability and Sustainability in Northern Atlantic Coastal Plain
Scientists Look at Issue from Long Island to North Carolina Threats to groundwater availability and sustainability in the Northern Atlantic Coastal Plain are dependent to a large degree by the type of aquifers used for water supply, according to a new regional assessment by the U.S. Geological Survey. The water challenges faced in the highly populated area, which ranges from Long Island, New ...

High resolution multi-level monitoring for bedrock aquifers
This presentation describes a comprehensive approach for determining the nature, extent, transport and fate of contaminants at industrial sites on fractured rock, with emphasis on sedimentary rock, referred to as the Discrete Fracture Network (DFN) approach. Development of this DFN approach began at a sandstone site in California in 1997, where the initial version of a method for measuring ...

Why Is Water Level Monitoring Important?
Remote water level monitoring Whereas water level monitoring used to be done by manually, with engineers sent to record levels of water on a fixed, often monthly basis, the ever-increasing improvements to technology means that water level monitoring can now be done remotely. Telemetric devices allow for water levels to be recorded much more regularly. This data can then be sent to other ...

New tool could aid safe underground storage of CO2, says MIT
To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere. One possible approach involves capturing greenhouse gases such as carbon dioxide at the source -- an electric power plant, for example -- and then injecting them underground. While theoretically promising, the technique has never ...
