Water Wand
I came across this nifty invention in Popular Science online (www.popsci.com). Its called the SteriPEN and it really does sound like a dream companion for those who fear the purity of the water they drink. Dip the 'pen' in your glass of water and let it take care of the bacteria and protozoa floating around. It uses ultra-violet rays to do the trick. Check their website out for details on their products: http://www.steripen.com/emergency/index.html.

Q What should I do if there are particulates in the water?
A We recommend removing particulates from the water prior to treatment. There are many ways to accomplish this. River rafters and canoists often let their water sit overnight to allow the particulates to settle. Backpackers use everything from household coffee filters to panty house to our Pre-Filter to remove particulates.
