[pct-l] CDC recommendations for water treatment

[giniajim]

What was added to the quote was the phrase: ".... i.e. Steri Pen type products." 

 That phrase about the Steri Pen apparently wasn't in the original quote.

(English non-Major but wannabe jumping in here)...

  so.....

   "is not effective  against Cryptosporidium at normally-used levels."

  is NOT the same as what is in the original page: 

  "is not effective against Cryptosporidium at normally-used levels."



  interesting....

  You need to avoid altering content that you indicate as "transcribing".

  The line from your post:

  "5)   Ultraviolet light treatment of water is not effective   against 
  Cryptosporidium at normally-used levels. i.e. Steri Pen type products."

  is NOT the same as what is in the original page:

  "Ultraviolet light treatment of water is not effective against Cryptosporidium 
  at normally-used levels."


  That is not transcribing.  It is "interpretation".

  Steripen's site points to a number of independent tests that DO indicate 
  effectiveness against cyryptosporidium.
