  3. Soppi ci Golden Standard #1 Xeetu paj mu jamp: 1-Simili Rolling Boil (3 simili ci kaw 2,000 meetar / 6,560 pied): Ci Santar yu Etats Unis ngir saytu ak fàggu feebar yi (CDC), Mbootayu Wérgi-yaram ci Àdduna (WHO), ak Sosiete Médikal bu àll bi (WMS), bringing water to a vigorous rolling boil for 1 full minute (or 3 minutes at elevations above 2,000 meters / 6,560 feet where reduced atmospheric pressure lowers the boiling point of water to \(93\text{ degrees Celsius} / 199\text{ degrees Fahrenheit}\) or below) kills 100% of all human waterborne pathogens (Cryptosporidium, Giardia, bacteria, viruses, and amoebae) without exception.
  4. If you have no stove or fuel, use Backup Chemical Disinfection (Chlorine Dioxide, Unscented Household Bleach, wala 10% Povidone-Iodine) and DOUBLE the contact time for cold water: Chemical reactions slow down by 50% for every \(10\text{ degrees Celsius}\) (\(18\text{ degrees Fahrenheit}\)) drop in water temperature. In icy mountain snowmelt (\(4\text{ degrees Celsius} / 39\text{ degrees Fahrenheit}\)), you must double the standard 30-minute contact time to 60 minutes (or 4 hours with Chlorine Dioxide to kill thick-shelled Cryptosporidium oocysts), and remember to "bleed the threads" of your bottle cap.
  5. Pre-filter cloudy, muddy, or glacial-silt water through a bandana + settled decanting BEFORE boiling or adding chemicals: Turbidity (suspended clay, silt, and organic debris) shields bacteria and cysts from chemical oxidizers and UV light, and binds up free chlorine before it can kill pathogens. Let silty water settle undisturbed in a pot for 30 to 60 minutes, pour the clearer top layer through a folded cotton bandana or coffee filter, and increase chemical dosing by 2x if the water remains cloudy.
  6. If you have ZERO fire, ZERO stove, and ZERO chemicals, NEVER let yourself die of dehydration in the wilderness out of fear of Giardia: Dehydration causes orthostatic fainting, kidney injury, cognitive confusion, and death within 2 to 4 days, whereas Giardia takes 7 to 14 days to cause symptoms (by which time you will be safely out of the backcountry and near a clinic with metronidazole/tinidazole). Select the safest high-elevation spring or small feeder brook (upstream of livestock/beaver ponds), dig a 1-meter (3-foot) gravel-bar seepage well ("Gypsy Well"), use 6-hour clear-bottle Solar Disinfection (SODIS) if sunny, and drink to stay alive.

Danger

What Boiling and Chemical Tablets Can NEVER Remove: Boiling and chemical disinfectants (Chlorine Dioxide, Bleach, Iodine) only kill biological living organisms (viruses, bacteria, and protozoan cysts). They do NOT remove heavy metals or chemical toxins (such as arsenic and heavy-metal runoff downstream of abandoned alpine mines, agricultural pesticides, petroleum spills, or neurotoxins/hepatotoxins produced by blue-green Cyanobacteria / Harmful Algal Blooms (HABs)). In fact, boiling water that contains a green cyanobacteria algal bloom lyses (bursts) the algae cells and releases more heat-stable microcystin toxin into the water. Never drink from stagnant ponds covered in green paint-like scum or orange acidic mine-tailing creeks (pH < 4).

According to the US Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and the Wilderness Medical Society (WMS), bringing water to a vigorous rolling boil for 1 full minute (or 3 minutes at high elevations above 2,000 meters / 6,560 feet) kills 100 percent of all waterborne human pathogens, including Cryptosporidium, Giardia, bacteria, and viruses. Even though water boils at a lower temperature at high altitude (for example, 89 degrees Celsius / 192 degrees Fahrenheit at 3,350 meters / 11,000 feet), all waterborne pathogens are rapidly inactivated once water temperature exceeds 70 to 85 degrees Celsius (158 to 185 degrees Fahrenheit).

Does household bleach or first-aid kit iodine kill Cryptosporidium in backcountry water?

No. While unscented household chlorine bleach (2 to 4 drops per liter for 30 to 60 minutes) and 10% povidone-iodine or 2% tincture of iodine (5 to 16 drops per liter for 30 to 60 minutes) are highly effective against bacteria, viruses, and moderately effective against Giardia cysts, neither bleach nor iodine can penetrate the thick, triple-layered outer shell of Cryptosporidium parvum oocysts. To kill Cryptosporidium without a filter, you must either boil the water, use Chlorine Dioxide tablets/drops (Aquamira or Katadyn Micropur MP1) with a full 4-hour contact wait time, or use UV light (SteriPEN or 6-hour clear-bottle solar SODIS).
