In other words, if your hands are dry you are okay for Giardia (but you should still wash them because of other disease causing bacteria). The big danger comes when you are pumping and you have wet hands from the water source and you are handling your bottles. The threads on your Nalgene are often the culprit, since they stay wet for a long time and are first thing you touch with your hands and with your lips. The threads are especially over looked when using iodine, polar pure or potable aqua to make your water potable. you should always screw the cap of your bottle on loosely and turn the bottle upside down letting the water containing the purifying agent run over the threads for a few seconds. (with potable aqua you have to wait for the tablet to dissolve and then you can do the upside down bottle trick. > Eric
