I was getting work done on wifes car and at the store they had a National Geograpgic magazine and the title was something like "Our need for water" or something along those lines. If anyone on here has the magazine maybe they can be more specific.

So, there was a page and it explained that now in Africa they are taking water from well or puddle etc and putting in a clear water bottle (like aquafina etc) and putting them on sheets of tin that are in direct sunlight for 6 hours and it kills the bacteria and viruses using the suns UV.

Thought some of yall might like to know there is yet another alternative to making safe water.

EPA rethinks plastic bottle component's safety aspects

Nonetheless, health officials suggested a number of things people could do to limit their exposure to BPA, like throwing away scratched or worn bottles or cups made with BPA (it can leak from the scratches), not putting very hot liquids into cups or bottles with BPA and checking the labels on containers to make sure they are microwave safe. The drug agency also recommended that mothers breastfeed their infants for at least 12 months; liquid formula contains traces of BPA.

BPA has been used since the 1960s to make hard plastic bottles, sippy cups for toddlers and the linings of food and beverage cans, including the cans used to hold infant formula and soda. Until recently it was used in baby bottles, but major manufacturers are now making bottles without it. Plastic items containing BPA are generally marked with the number 7 on the bottom for recycling purposes.

Water pasteurization indicator

Water pasteurization indicator

How can one determine if heated water has reached 65° C? In 1988, Dr. Fred Barrett (USDA, retired) developed the prototype for the Water Pasteurization Indicator (WAPI). In 1992, Dale Andreatta, a graduate engineering student at the University of California, Berkeley, developed the current WAPI. The WAPI is a polycarbonate tube, sealed at both ends, partially filled with a soybean fat which melts at 69° C ("MYVEROL" 18-06K, Eastman Kodak Co., Kingsport, TN 37662).
Biocidal silver

I'm thinking colloidal silver might be worth looking into, being that NASA has been using it in space craft for years....

In the 1960s, NASA’s Manned Space Center (now known
as Johnson Space Center) and the Garrett Corporation,
Air Research Division, conducted a research program to
develop a small, lightweight water purifier for the Apollo
spacecraft that would require minimal power and would
not need to be monitored around-the-clock by astronauts
in orbit. The 9-ounce purifier, slightly larger than
a cigarette pack and completely chlorine-free, dispensed
silver ions into the spacecraft’s water supply to successfully
kill off bacteria. A NASA Technical Brief released around
the time of the research reported that the silver ions did not
“impart an unpleasant taste to the water.”
