Water is, understandably, high on the survivalist’s priority list. Dehydration can kill a person anywhere from a few days to a week, depending on the individual situation. So whenever I get a chance to check out a new water purification method, I jump right on it. This time, I got a couple of bottles of Purinize Water Purifier Solution to play around with.
Purinize states that their non-toxic sulfate mineral salt solution is superior to other chemical methods because it’s effective at any temperature above freezing, at any pH, for any objectionable substances in your drinking water, whether it be organic, chemical or heavy metals, and that treatment can take as little as 5 minutes.
Now, because I don’t have a laboratory to test these claims, I have to rely on the lab results of trustworthy labs. Looking at the Purinize website, I was surprised that I was unable to easily find a citation of a reliable third-party to verify the company’s claims. Finally, I found a footnote that states the following:
Tests conducted by an EPA certified laboratory demonstrate that our Purinize reduces E-Coli 100%,
Giardia 99% and Cryptosporidium 97.1%. All laboratory tests were conducted using a 0.2 micron filtration system for removal of precipitates.
What puzzles me is that there was any Giardia or Cryptospridium left in the water after going through a 0.2 micron filtration system, since both of these are greater than 3.0 microns at the narrowest. Not to mention, the reduction in E-Coli, Giardia and Cryptospridium could all be attributed to the 0.2 micron filter, whether or not the Purinize had even been added. These observations, combined with the fact that the EPA certified laboratory remains anonymous, makes the footnote less trustworthy to me.
I was able to find a post that stated that Purinize was effective against a chemical that had spilled into a river in Virginia. However, the EPA lab was once again anonymous, and the listed times for the tested reductions in the chemical were 12, 24, and 48 hours.
Having not had much luck with my research, I proceeded with my own experiment. I got some water from a nearby creek. The sample jar was pretty cloudy, with lots of little floaties in it. I let the sample sit for a day to reach room temperature, and then added the Purinize to the sample jar and to a control jar, which just had tap water.
After 5 minutes, I wasn’t seeing much. After 10 minutes, I strained the creek water through a coffee filter, because I thought there might be too many big chunks, and there were some little critters swimming around in there. I think they were a little agitated by the Purinize, since I didn’t notice them before I treated the water. The test water was still a little cloudy, so I added a second dose of Purinize.
After about an hour, I noticed a precipitate on the bottom. The water was somewhat clearer, but still stank of pond scum. Finally, after about 4 hours, the water was almost as clear as the sample jar and smelled much better, although it still had a little smell of pond water. I decided to leave it overnight. After 24 hours, the clarity of both jars was the same, and there was only a slight hint of pond water smell in the test jar.
After not finding satisfactory laboratory evidence of effectiveness, and still being able to smell a hint of swamp stink, I opted not to drink the test jar. However, I did take a taste of the sample jar, and the Purinize did improve the taste of the tap water, so I don’t doubt that the test water also would have tasted much better after the treatment.
All in all, I don’t know that I can whole-heartedly recommend the use of this product by itself, simply because I don’t have the ability to test for microorganisms, and I can’t find evidence that Purinize does an effective job of making water safe enough to drink. However, Purinize definitely will improve the quality of the water in some degree, and would seem very likely to improve the effectiveness and longevity of filtration systems via the clotting of viruses and bacteria to a size that can be easily filtered. If you were to use this product in conjunction with a quality filtration system (as Purinize recommends on their website), then it may very well be a good addition to your water harvesting kit.
