I have no idea where these hikers get their water but, if it is coming from streams, ponds, open springs, etc., I would be far more inclined to suspect that the treatment process was insufficient than to suspect the treatment chemicals themselves as the source of my problems. Could there be other things in open surface water sources that could make one sick besides some pathogens that may or may not have been completely treated? As Neal pointed out, the average person drinks a lot of phosphoric acid over a lifetime in sodas. How does that compare with the concentration and total quantity that was consumed in the treated water? Did she get an adequate medical diagnosis (I realize some of these problems are not easy to diagnose but is a toxicological description of the treatment chemicals more exact?)? In my opinion that is where her effort should be directed first.Al--On Wed, Jul 23, 2014 at 8:19 AM, Frankie Wood-Black <fwblack**At_Symbol_Here**cableone.net> wrote:
This is a reporter that is looking for some help on a story - anyone what to contact him? There is a part A and a part B - the part B has phosphoric acid - both MSDSs (SDSs) put out by the company indicate irritation if ingested at large dosages.I think he needs to have an IH talk with him.

Hey Frank,I would gladly take you up on your offer to be put in touch with any colleagues you think might be able to help.One of the most popular water treatment options amongst Appalachian Trail thru-hikers is Aquamira, a chlorine dioxide chemical solution. As you point out, the dose makes the poison- however due to the extreme demands of long-distance backpacking, it's common to ingest between 5-8 liters of water per day. Multiply this times 4-6 months (how long it takes to cover the full distance of the trail). Since my thru-hike in 2011, I have battled severe digestive issues, and I have talked with others (who've used Aquamira) who say the same. If there is any truth to this being unsafe in high volumes, I'd like to help spread the word and prevent future hikers from suffering.Any help you can offer would be greatly appreciated.Best,Zach

Hello Zach,
Here's another pitch from a HARO source! Hope you find the perfect match for your story.
Best,
The Vocus Team
---------------------------------
Pitch Title: Your request on chlorine dioxide
Pitch Contents:
You really need to contact the American Chemical Society - they can put
you in touch with the correct person. My recommendation is that you need
to talk with an industrial hygienist as they are more trained in how
chemicals are used/misused and toxicity levels. A chemical toxicologist
is someone else you might talk with. I can put you in touch with a
couple of colleagues of mine that may be able to help. As with most
things it is a matter of dose.
