Considering that less than 1 percent of all the water on the planet is usable freshwater, we’re not nearly as careful as we should be with this precious resource. Here are some amazing facts to put things in perspective.

1. Set in the desert of Dubai, the Tiger Woods Golf Course uses 4 million gallons of water every day to maintain its lush appearance.

2. Since 1950, water usage in the United States has risen 127 percent.

3. Even though each person only requires 48 liters of water on a daily basis, individuals in the United States use an average of 500 liters, those in Canada an average of 300 liters and those in England an average of 200 liters.

4. Of all the water that enters each household, about 95% of it ends up down the drain.

5. With access to just 5 liters of water each day, more than a billion people in water poor regions around the globe survive on the same amount used to flush a toilet or take a 5-minute shower.

6. If you shorten your showers by just a single minute, you can save approximately 700 gallons of water in a month.

7. Letting the tap run when you brush your teeth wastes up to 4 gallons of water every time.

8. It takes an average of 300 gallons to water your lawn. During the summer, this can account for almost half of your water usage.

9. Every time you throw your clothes in the washer, you use about 50 gallons of water.

10. Another wasteful desert endeavor, the proposed Waveyards water park in Mesa, Arizona will require up to 100 million gallons of groundwater every year in an area that receives a mere 8 inches of rainfall in that time.

Move over, melamine; your infamy as a contaminant in Chinese infant formula is being pushed aside by one that’s made in the USA. The Center for Disease Control (CDC) has found some samples of American brands of infant formula (although they won’t divulge which) are contaminated with perchlorates – which come from rocket fuel.

How, one has to wonder, are perchlorates getting into the formula many people are feeding to their newborn babies? Improper disposal on military bases, rocket test sites and chemical plants can allow perchlorates, which affect the thyroid, to leach into drinking water. That means these chemicals may be harming you, too. So far, the EPA hasn’t set a “safe” limit for perchlorates in drinking water, but I hope this issue will force the agency to take a closer look and regulate.

Living in New Zealand, a country that has, in my opinion, the best and safest drinking water, it’s hard to imagine that one-sixth of the world’s population (nearly one billion people) are without clean water on a daily basis.

Most of us simply acknowledge information such as this by finding an organization to donate some money to help fund clean water campaigns and then move on to the next pressing issue. But some Iowa engineering students didn’t. They heard the facts and then rolled up their sleeves and designed a $5, hand-held device that can sanitize water, saving lives as a result.

What started as a simple class project has developed into something much, much bigger. The hand sanitizer took away the First Prize at the 2008 Environmental Protection Agency Awards, a prize that is worth $75,000. The win is prestigious enough but to the students at UI College of Engineering, the money is the key, for it’s going to be used to make water sanitizers available to Ghana and other developing countries in the future.
