North Country Public Radio in Canton, New York, reports that geoscientists have been noticing a change in the groundwater throughout the northeast. It is getting salty.
Dr. Nancy Karraker, an Assistant Professor of Wetland Ecology at the University of Rhode Island, said she and other biologists have been documenting an increase in the salinity of groundwater. The problem with salt is that plants do not take it up, it does not bind to soils and so over time as it makes its way into wetlands, it concentrates, Karraker said. They concluded that the likely main culprit is the salt used on roa... More →

Many Ohio soil factors influence pesticide adsorption. Soils high in organic matter or clay are more adsorptive than coarse sandy soils because a clay or organic soil has a greater particle surface area or number of sites onto which pesticides can bind.

Olariu and Ambrose report that the Wilcox Group is a 3,000 m thick unit of clastic sediments deposited along the Gulf of Mexico coast during early Paleogene. This study integrates core facies analysis with subsurface well-log correlation to document the sedimentology and stratigraphy of the Lower Wilcox Guadalupe Delta. Core descriptions indicate a transition from wave- and tidally-influenced to wave-dominated deposition. Upward-coarsening facies successions contain current ripples, organic matter, low trace fossil abundance and low diversity, which suggest deposition in a fluvial prodelta to ... More →

To predict contaminant migration, implement remediation strategies or design a disposal facility, one must know the transport properties of the units beneath the site as well as any engineered parts of the system, e.g., grout, gravel, or geotechnical barriers. The single most important transport property is the hydraulic conductivity (K) which is a strong, non-linear function of the volumetric water content. For many performance assessments and licensing requirements by the EPA and NRC, contaminant release rates and groundwater travel times must be determined. For the vadose zone, the most imp... More →

Gulf Coast Countries are seeing the largest gaps between renewable water supplies and demand. Currently Bahrain uses 220 percent of its renewable water reserves vs. 943 percent for the Saudi Kingdom and 2,465 percent for Kuwait.

The Kingdom has not rivers or lakes and therefore, water demand from groundwater is 98% with the remaining percentage from desalination plants. Of that 98%, 95% is utilized for industrial and human consumption.

Databases, by SOILECTION, offers the following options. Search conditions generate technical descriptions of remediation techniques and practical experience (cases). The cases make it possible to assess the applicability of soil remediation techniques. The database is complemented with information from the HIP pilot program. Information from practice show which techniques are most effective in certain conditions. The SOILECTION website allows you to compare cases with your own planned remediation project.

John Simmons reports in The Geoscientist Online of the Geological Society of London that geologists in the energy industry can improve their company financial performance, environmental impact and engagement by reviewing their involvement with water, writes John Simmons. In the increasingly vibrant debate about the effect of energy production on the environment, the focus has been largely on anthropogenic CO2 and the need to leave hydrocarbons in the ground. While that debate rages in forums at national and international level, another aspect of energy production, with a significant effect lo... More →

Kevin McCray reports that among the available data are indications of at least an apparent short-term downward trend for new residential water well construction. The data suggest the percentage of new single-family houses completed in the United States with individual water service - primarily wells - may have dropped from about 12.5 per cent to about 8 per cent from 2009 to 2013.
