(Natural News) As part of 2019 effort to conduct more lab science in the public interest, we are announcing glyphosate testing for water filters. The experiment, carried out at CWC Labs, will pour diluted glyphosate (2ppm glyphosate in water) through popular water filters, then test the resulting "filtered" water to see how much glyphosate is removed.

The water filters being tested include:

Culligan

Brita

Mavea

Pur

pH Life

Seychelle

Big Berkey

Crystal Drop

Doulton

Zero Water

I've posted the full video announcing this experiment at this Brighteon video link. (Or see the full video below.) Full results of the experiment will be posted exclusively at Glyphosate.news in the coming days. Natural News will link to the Glyphosate.news results and announce them in the Natural News email newsletter.

Why we use a triple-quad mass spec instrument to test for glyphosate

The instrument we use to measure glyphosate concentrations is a triple quad mass spec (LC-MS-MS), capable of detecting glyphosate well below 1 ppb. This instrument is shown in the video below.

As I explain in the video, I doubt whether any of these popular water filters will show much effectiveness at removing glyphosate. Many water filters claim to remove "99% of pesticides" and other chemicals, and while that may be true with specific, individual pesticides, it seems incredibly unlikely that any filter would remove anywhere close to 99% of glyphosate.

Here's why: Glyphosate is water soluble and does not easily interact with the chemistry of water filter media. Where lead and mercury, for example, are easily captured by activated carbon, glyphosate moves right through activated carbon. In addition, glyphosate is highly polar, meaning  the glyphosate molecule has strongly opposite charges on the two ends of its molecule. As explained in this Perkin Elmer document quoted below, most labs have traditionally used something called "post-column derivatization" in their methods to detect glyphosate, involving the use of extremely toxic chemicals:
