Global Challenges/Chemistry Solutions debuts with focus on drinking water
Date:6/25/2008

WASHINGTON, June 25, 2008 An authority on the quality of drinking water today describes new challenges for consumers and municipal water supply systems, including unexpected consequences of efforts to conserve water in the first of a special series of podcasts from the American Chemical Society (ACS), the world's largest scientific society.

Marc Edwards, Ph.D., notes that reduced-flush toilets, low-flow showerheads and other well-intentioned water conservation efforts are allowing water to remain in household pipes longer. As water stagnates in pipes, it may develop undesirable characteristics and have unwanted effects on household plumbing, Edwards indicates.

He discusses the topic in "The Crisis in Clean Water: Water Purification," the inaugural episode of Global Challenges/Chemistry Solutions. That series of podcasts focuses on daunting global problems and how new discoveries from the labs of chemists and other scientists offer solutions. The topics include coping with climate change, combating disease, providing safe food, developing new fuels, preserving the environment, assuring personal safety and national security, and promoting public health.

Each podcast will be available without charge for listening on computers and downloading to portable audio devices at iTunes (requires iTunes software) and other podcasting sites. They also can be accessed on ACS's Global Challenges web site. The site provides audio links and full transcripts of each podcast. Additional resources on each Global Challenges topic also are available, on the site, including information for consumers, students, and educators.

Debut of the first podcast coincides with publication of a special edition of Environmental Science & Technology, one of ACS' 36 peer-reviewed scientific journals. It is devoted to global water issues. Key articles from the journal can be viewed without charge at [http://pubs3.acs.org/acs/journals/toc.page?incoden=esthag].

The podcast describes an increasingly serious global shortage of clean drinking water, which claims a huge toll in illness and death in developing countries. It presents examples of scientific research that are reducing that toll today, and promise to have further impact in the future. Global Challenges describes one, for instance, as "The Miracle Packet." These pennies-a-piece packets work like a municipal water purification facility to kill germs, remove harmful substances, and make dirty water fit to drink.

Edwards emphasizes that people in the United States generally enjoy tap water of "very good" overall quality. One exception involves relatively small numbers of children exposed to high levels of lead in their drinking water, he said.

Edwards describes newly emerging concerns, including tap water safety for individuals with weakened immune systems, home plumbing corrosion caused by water purification plants switching to chloramine disinfectant, and water stagnating in household pipes.

With consumers using less for flushing of toilets and showering, water sits in household pipes for longer periods, said Edwards, who is with Virginia Tech. Substances formed as chloramine breaks down can corrode plumbing, and have more time to do so when water stagnates.

Edwards indicated that stale water also can loose the disinfectant added at municipal water purification facilities, allowing bacteria to multiply. "So just like milk can go bad if it stays around too long, so too can potable water go bad, and we are discovering this is a downside of water conservation," he said.

The next Global Challenges/Chemistry Solutions podcast, due in July, deals with advances in water desalination technology that promise to provide a drought-proof supply of fresh water from the sea.
