  1. I’m at a bit of a loss after reading your comments about RO.

    RO (reverse osmosis) is used extensively to prepare water for drug manufacturing. From an FDA publication: [In recent years, RO has been used increasingly in making processed water for dialysis in hospitals and for certain cosmetics and drugs by pharmaceutical manufacturers. In addition to these applications, RO is capable of producing water of sufficient purity to be used as Water For Injection (WFI) and for the preparation of parenteral solutions.] (https://www.fda.gov/ICECI/Inspections/InspectionGuides/InspectionTechnicalGuides/ucm072913.htm) It will certainly remove larger molecules such as radionuclides, cyanotoxins and viruses. Indeed, it can remove salt from seawater to produce drinkable water (used on every US Naval vessel, and included in life support kits for larger lifeboats). Since salt is a substantially smaller molecule than any virus…(and RO water can be used to safely make solutions for injection)… I’d submit that the only disadvantage to RO water is the cost of the equipment and the energy needed to push the water molecule through the semi-permeable membrane. Depending on the quality of the input water… some pretreatment may be needed to ensure that the membrane doesn’t get clogged.

  2. My goodness if it is this much of a pain to just get water when the world is falling apart, take me home Jesus. Get the best filter you can and try to use running water but then just pray over it and move on.

  3. I think the main idea that the author is trying to pass along is that you first must locate as clean a water source as possible and look for possible dangers. From there, take necessary steps to assure what you have is as safe as possible because any water source could be compromised by these cyanotoxins or radiation etc. You can not be 100% certain that your water is 100% safe.

  4. I’m wondering if the writer of the article can address another problem with groundwater. Since virtually everyone is downstream from a municipal sewage system releasing effluent into rivers, streams, and lakes, do the EPA accepted municipal sewage systems practices remove the synthetic Dr. prescribed pharmacy drugs in the water.

  5. While having the car serviced, I was reading the Nov 28 Wall Street Journal. Some news you might like.

    The article on the great increase in rock-climbing noted that fingerprint readers are useless with rock climbers because the calluses obscure the ridges.

    In another article, The stock price of Dick’s Sporting Goods has taken a hit since they instituted their recent firearms sales restrictions.

    Carry on.

  6. Quibble: Bacteria and Viruses are NOT toxins.
    A toxin is a molecule or compound (or element) which is harmful.

    1. It depends on the dose. If I’m getting to safety, one spring that might have heavy metals is worth drinking but not over time.

    2. You can kill organisms.

    3. distilling or filtering will remove most nasty things which don’t evaporate with the water.

    4. the things you can’t remove via distilling and (molecular) filtering are rare, so don’t drink where there’s an empty barell labeled phenol or xylene.

    Know your toxin (or potential) and act accordingly. In the deep blue zones it will be different than the deep red.

    Even in the deep red, remember animals can be carriers.
