Reading about Real Water poisoning people with hydrazine recently threw me for a loop… Source

After traditional filtration methods:

Then potassium chloride is added and the water goes through a proprietary “ionizer” apparatus to apply an electrical current to the water. This allegedly created positively charged and negatively charged solutions. Real Water employees would discard the positively charged solution and keep the negatively charged solution.

That initial batch of negatively charged solution would then go through the “ionizer” apparatus and be separated again. The resulting negatively charged solution would then be treated with potassium hydroxide (a form of lye), potassium bicarbonate (sometimes used in baking powders), and magnesium chloride (a salt used in nutritional supplements and for de-icing roads); this formed an “E2 concentrate” product, which, when diluted, formed their alkaline water product.

The FDA identified hydrazine in product samples it tested. In the trial, Issam Najm, an environmental engineer who specializes in water chemistry and testing, testified that the hydrazine likely formed in the “ionizer,” which was just titanium tubes electrified with what looked like jumper cables used to charge a car battery. Najm testified that, in the charged water, nitrogen gas naturally found in air could have reacted with water to form hydrazine (N2H4), or, during the electrolysis, ammonia (NH3) was formed first, before reacting with hydroxide to form hydrazine.

It makes me think of the irradiated water that was marketed for “vigor!” and bogus cures in the 20s. Still too much snake oil and pseudoscience…
