LifeStraw Use Report and SODIS

[Carl Clifford <>]

Dear B-A,

Last year I mentioned a cheap, easily carried water purification  
device, LifeStraw, as a potentially useful addition to a birder's  
kit . In October, I took a LifeStraw with me on a trip to Sabah and  
tried it in water of varying qualities, from urban tap water to raw  
river water. Water through the LifeStraw was quite palatable and I  
suffered no ill-effect from water borne organisms. I would recommend  
the LifeStraw as part of a birders kit, even if only for emergency use.
I have just returned from a trip to Yunnan, on which I did not take  
the LifeStraw. I am still recovering from a bad case of Giardiasis  
which I contracted from a town water supply. Next trip, all my  
drinking water will pass through a LifeStraw, much cheaper than  
Doctor's visits.
Another, even simpler water purification method that birders might  
find useful, particularly on camping trips, is SODIS (solar  
disinfection). SODIS uses clean PET or glass bottles filled with water  
and placed in the sun for 6 hours or more. A very simple and elegant  
solution to water purification. For information on SODIS, see  http://www.sodis.ch/index_EN

Cheers,

Carl Clifford
