Originally thought to be non-toxic, tungsten is replacing lead in fishing weights and in ammunition for hunting and recreational shooting. However, recent studies indicate that (under certain environmental conditions) some forms of tungsten can move readily through soil and leach into groundwater. A Kansas State University scientist investigates. Tungsten is a naturally occurring metallic element ...

When water travels through soil and bedrock to the water table, it carries minerals, nutrients or chemicals from the surface with it. Environmental research is increasingly concerned with preferential flow, or the movement of water through pores and cracks at a faster rate and bypassing most of the surrounding material, either soil or fractured rock. A special section on preferential flow ...

Quantifying water movement and contaminant transport in the Earth’s subsurface are the critical issues addressed during presentations offered through the 2017 Henry Darcy Distinguished Lecture Series in Groundwater Science. Earth’s subsurface is part of the “critical zone” — the layer of the planet from the tops of the trees to the bottom of groundwater. This zone is ...

VisualRflow is a completely new reactive transport software, it is as fast as Bioscreen but as powerfull as RT3D. VisualRflow is dedicated ot 2D horizontal saturated flow and transport of dissolved reactive species. It is largely oriented towards natural attenuation, but can deal with other cases. The interface is a simplified pre- and post-processor for Modflow, when flow has been calculated, ...

Contamination of drinking water in areas close to several fracking sites in the Marcellus and Barnett Shales, USA, is caused by structural problems leading to wells leaking natural gas into aquifers, a new study suggests. The researchers measured trace amounts of chemicals, called noble gases, which formed signatures of the sources of gas contamination in over 130 samples. These findings suggest ...

Each person in the US state of Florida uses about 1,720-2,160 liters of water per day, and with thousands of people moving to the state each month, public water supply needs near DuPont's plant are expected to double by 2025. Drinking water comes from two sources: surface water and groundwater. Supplying drinking water to a growing state like Florida is a challenge because 90% of the state's ...

Concern about microbial contamination of groundwater from foraging dairy cows has increased as spray irrigation practices in New Zealand have increased over the years. Bacteria capable of living in both animals and humans are commonly found in cow manure. Addressing the lack of research on the topic, a team of New Zealand researchers studied the transport of microbes from two spray irrigated ...
