Water •Hydration is key to performance or even survival. •Don’t wait until you are thirsty to drink, by then you are already beginning to dehydrate. •Clear urine is the best indicator of proper hydration. •Should drink a MINUMUM of 2 quarts per day. Water Sources: From The Tap •Pack in yourself •Good for day hikes •Guaranteed safe--no purification needed •For Winter, it is best to fill your bottle with hot tap water immediately before hiking. Water Sources: Lakes, Rivers & Snow •Most practical for multiday trips (water is heavy!). •Lakes and rivers are convenient. •Melting snow is the usual method in Winter--Takes time and fuel. •MAJOR PROBLEM: Contamination. •Frequently the water needs sterilization or purification. Water Purification: Boiling •Boiling is the best methods--it kills everything •Just bring the water to a boil briefly. •Fresh fallen snow should be boiled too, because pathogens survive and can be mixed in from old snow. Water Purification: Iodine •Iodine treatment is effective against bacteria and viruses, but not large parasites. •Since iodine tablets dissolve slowly in cold water, you may have to •wait up to an hour before drinking the water. •After treatment taste can be improved by reacting the leftover iodine with powdered vitamine C •Making punch or Kool-Aid helps the taste too. Water Purification: Filtration •Filters are effective against large parasites and bacteria, but not viruses •Make sure the filter pore size is no larger than 40 microns, or else bacteria will get through. •A combination iodine/filter is available and works well, but you have •to carry the extra weight (about a pound). Waterborne Pathogens •Virus:Hepatitis A (infectious hepititus)-not common •Bacteria: Salmonella and Escherichia coli--not common in US •Large Parasites: Giardia and Cryptosporidium (“crypto”) are very common.
