"Water, one of the most precious of resources, continues to be the most mispriced," says Neil George.

In his Profits Hidden in the News advisory, he explains, "Millions of Americans are drinking dangerous water from the tap." Here, he looks at two ways to profit as this situation gains attention.

"The US Environmental Protection Agency has recently updated its data on US municipal water and, as with previous surveys and reports - the news is not good. In fact, for wide swaths of the US population - including those in the nation's capital - its flat out scary.

"The worst crisis of all time, in my view, is the critical global shortage of fresh water," says " Larry Edelson. In Money & Markets, the resource expert offers four water sector plays.

"The world's water crisis is now getting worse by the day. And the global financial and credit crisis is merely one reason why. Another is the ongoing modernization of major parts of the world, which is increasing demand for water, while at the same time polluting it.

"Yet another is major droughts around the world, including in our own back yard, where 60% of the U.S. is officially experiencing a drought.

"New technologies and techniques for better water supply management and improved conservation on the demand side could potentially avert a worldwide disaster. And as a long-term investment, water is one of my favorites. For both its tremendous social cause as well as its profit potential.

"Water is the sleeper investment of the decade," says Jim Powell. "Although the world is focused on energy, clean water is in far shorter supply in many regions. That's even true in many parts of the U.S."

The editor of Growth Stock Alert suggests, "A great deal of money will be made by today's earlybird investors who buy strategic water stocks." Here are his favorites in the sector.

"Unlike oil, there is no substitute for water. Some investors mistakenly think that water is a low value commodity that's not likely to deliver good profits. What the critics fail to consider is the equipment needed to
obtain, purify, transport and recycle water is very expensive.

"Calgon Carbon (NYSE: CCC) is my first choice in a water stock. The company is the world's largest supplier of
granulated activated carbon, the principal purification agent for water. The company also supplies complete treatment systems for municipalities and private organizations.

"The company has 16 operating centers and 23 sales and service offices around the world. A few years ago

, the company expanded its purification business to include industrial liquids and gasses. Rising concerns about greenhouse emissions and other pollutants are giving Calgon Carbon another boost.

"I also recommend ITT Corporation (NYSE: ITT), the world's leading supplier of systems that move and purify
water. The company's treatment equipment is sold throughout the world under the Sanitaire, Aquious and WEDECO brands.
