Supplying Safe Drinking Water
Did You Know?
|From San Diego to Santiago to Seville to Sydney, billions of people are facing shortages of clean water. More than one billion people have no access to clean drinking water. And things are getting worse.|

In India and Bangladesh, drinking water is contaminated with arsenic. Three enterprising scientists have each recently devised a way to remove arsenic from drinking water. Discover how they did it.
Today, we take for granted that our tap water is free of deadly germs. A century ago, Edward Frankland saved thousands of lives by showing Londoners how to safeguard their water supply.
Our tap water may be safe to drink, but many of us prefer to filter it for a better taste. Do some tests to find out how filtered water and tapped water compare.
Summertime, and the living is easy – if you know which chemicals will keep the swimming pool clean.
Yesterday’s bath water is today’s crystal clear drinking water, thanks to chemists at the wastewater treatment plant.
Chemical Abstracts Service (CAS®)
SciFinder®, a research tool produced by CAS (a division of the American Chemical Society), found 6381 references in the CAS databases on the topic of "water purification" published this year. The CAS databases cover references from more than 10,000 major scientific journals and 57 patent authorities worldwide. As an illustration of the global interest in this topic, approximately 23% of these references were Chinese and Japanese patent applications. www.cas.org
