Is Your Drinking Water Safe?

03.03.2008
Lake Bloomington is a major source of drinking water for residents of Bloomington, IL, and has a history of nitrate concentrations that exceed safe levels. Because Lake Bloomington has a record of elevated nitrate levels, local residents are concerned over their drinking water quality.

Kenneth Smiciklas, Associate Professor of Agronomy, Illinois State University, along with a team of colleagues, present an article about the nitrate levels in Central Illinois in the 2008 Journal of Natural Resources and Life Sciences Education.

According to Smiciklas, "Drinking water contaminated with nitrate concentrations exceeding the maximum contaminant level established by the USEPA can cause health effects in humans and animals."

Nitrate-nitrogen is a form of nitrogen that is naturally occurring in most soils. Nitrogen fertilizers added to the soil for crop production can also add to the soil nitrate concentration. If these amounts become extreme, drinking water quality can be affected.

More than 90% of the area in the Lake Bloomington watershed is used for agriculture. The application of nitrate fertilizers (both synthetic and organic) in the growing food crops can result in relatively high levels of nitrate in the surrounding waters. Non-agricultural sources of nitrate can include natural mineralization occurring primarily in the spring due to organic matter breakdown and also from septic emissions.

The main objectives of this study were to measure the sources of nitrate entering Lake Bloomington and to document the practices of producers within the lake area. "We hope the information from our study will help form recommendations on how to manage nitrogen fertilizers in sensitive watershed areas," concludes Smiciklas.

The full article is available for 30 days from the date of this summary as free access available here. After 30 days it will be available at the Journal of Natural Resources and Life Sciences Education website, www.jnrlse.org. http://www.jnrlse.org/issues/ (Click on 2008, Volume 37, "View Article List," scroll down to article abstract).

Today's educators are looking to the Journal of Natural Resources and Life Sciences Education, http://www.jnrlse.org for the latest teaching techniques in the life sciences, natural resources, and agriculture. The journal is continuously updated online during the year and one hard copy is published in December by the American Society of Agronomy.

The American Society of Agronomy (ASA) www.agronomy.org, is an educational organization helping its 8,000+ members advance the disciplines and practices of agronomy by supporting professional growth and science policy initiatives, and by providing quality, research-based publications and a variety of member services.

Im Focus: High-pressure scientists in Bayreuth discover promising material for information technology

Researchers at the University of Bayreuth have discovered an unusual material: When cooled down to two degrees Celsius, its crystal structure and electronic properties change abruptly and significantly. In this new state, the distances between iron atoms can be tailored with the help of light beams. This opens up intriguing possibilities for application in the field of information technology. The scientists have presented their discovery in the journal "Angewandte Chemie - International Edition". The new findings are the result of close cooperation with partnering facilities in Augsburg, Dresden, Hamburg, and Moscow.

The material is an unusual form of iron oxide with the formula Fe₅O₆. The researchers produced it at a pressure of 15 gigapascals in a high-pressure laboratory...

Im Focus: From China to the South Pole: Joining forces to solve the neutrino mass puzzle

Study by Mainz physicists indicates that the next generation of neutrino experiments may well find the answer to one of the most pressing issues in neutrino physics

Among the most exciting challenges in modern physics is the identification of the neutrino mass ordering. Physicists from the Cluster of Excellence PRISMA+ at...

Im Focus: Therapies without drugs

Fraunhofer researchers are investigating the potential of microimplants to stimulate nerve cells and treat chronic conditions like asthma, diabetes, or Parkinson’s disease. Find out what makes this form of treatment so appealing and which challenges the researchers still have to master.

A study by the Robert Koch Institute has found that one in four women will suffer from weak bladders at some point in their lives. Treatments of this condition...

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...
