Arsenic Removal From Drinking Water is Focus Of New Products

07.04.2005


More stringent federal standards for acceptable levels of arsenic in public drinking water go into effect next year, a prospect that has resulted in four new research projects on arsenic.

The research, funded by the Midwest Technology Assistance Center for Small Public Water Systems, will address the new standards, which will change the acceptable level of arsenic in public groundwater supplies from 50 micrograms per liter to 10 mg/l. The center, housed at the Illinois State Water Survey, is a joint effort between that agency and the Water Resources Center at the University of Illinois at Urbana-Champaign.

Chronic exposure to high arsenic concentrations can cause cancer and other diseases. Private water supplies are not subject to regulations, but high arsenic concentrations do occur in many private wells.

"We feel the work we’re funding, especially on arsenic, really is making a difference," said Kent Smothers, the managing director of the center. "Such projects are critical to small systems throughout the Midwest."

The center, one of nine throughout the United States, receives annual funding from the U.S. Environmental Protection Agency and provides grants or direct funding for work by state and university researchers on key areas for small water systems.

The projects include optimizing iron addition for arsenic removal at existing facilities, examining conditions that may control arsenic release into groundwater supplies, and tracking arsenic concentration variability in relation to time and pumping procedures. A new technique for more effective arsenic removal than existing methods also is being examined, Smothers said.

Arsenic isn’t the only focus of the center’s research.

"Water quality at surface water intakes is being evaluated with watershed modeling," Smothers said. "Comparative performance measures being developed will improve technical, managerial, and financial capacity of small systems. Drought planning for small systems is another important area being assessed."

More information about MTAC and other Centers is available on the Web. The ISWS Public Service Laboratory provides analyses of water quality free of charge for owners of domestic wells, Smothers said.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
