Highest concentration of specific ground water contamination in northeast US


The presence of methyl tert-butyl ether (MTBE), a component used to add oxygen to gasoline to meet Clean Air Act standards, has been detected as a contaminant in ground water supplies underlying urban areas, particularly in the northeastern United States. The study is published in the July-August issue of Ground Water.

Researchers from the U.S. Geological Survey examined the occurrence of MTBE and gasoline hydrocarbons in ground water throughout the United States and found that nationwide, MTBE was detected as frequently as some other chemicals that have been used for longer periods of time. MTBE was detected more frequently in urban areas compared to other land use types, such as agricultural areas, putting shallow ground water supply in these areas at risk for contamination.

"It is not known if contamination of shallow ground water in urban areas will reach deeper aquifers that are generally used for supplying drinking water," states Michael J. Moran, lead researcher. "Few concentrations of MTBE in ground water exceed the current USEPA Drinking-Water Advisory. This means that most MTBE concentrations in ground water will not cause taste and odor concerns. However, low concentrations of MTBE in drinking water may have unforeseen health consequences."

Past research has shown that possible human health consequences as a result of MTBE contamination in drinking water include carcinogenesis and detrimental reproductive and developmental effects. Researchers say determining the factors related to the occurrence of MTBE, as in this study, may help to reveal the sources and pathways of MTBE to ground water, and the vulnerability of aquifers to MTBE contamination.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
