"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.
