Highest concentration of specific ground water contamination in northeast US

19.07.2005


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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
