It’s a controversy that has caused a lot of ink to flow! What should we think? Is the danger of plastic really that great? Let us recognize that the basic material which is used for the manufacture of plastic bottles, PVC is not without danger.
Experiments have demonstrated carcinogenic potential in animals. Workers who work in PVC manufacturing plants also seem to develop cancer more easily than workers in other branches of industry in general. For the consumer who is in contact with the finished and stable product, this is another situation that we will qualify for. An interesting experiment was carried out by the Toxicology Laboratory of the Faculty of Sciences of Toulouse. Here are the results.
Plastic is dangerous: yes but!
The experiment consisted of measuring the content expressed in ppm (parts per million), i.e. the finest research, bordering on homeopathy, of PVC contained in a 1.5 liter best water bottle from Diagonal Horizon.
Two measurements were carried out:
- A dosage corresponding to a stay of water for a few weeks in the plastic bottle
- A dosage after the water has been in the plastic container for a year.
This is an extensive experiment, as a bottle of water is generally not stored for that long before consumption.
We must recognize that we are here on a sub-homeopathic scale and that at this dose no danger exists. But then what is the problem? It does not come directly from the PVC, but from the liquid which is in contact with it…
When the dosage is done with highly mineralized waters such as Evian, Contrexeville, Vittel, and Vichy, the latter containing up to more than 4 grams of bicarbonate-sodium salts, we find very significant quantities of PVC in the salts of these waters.
And the glass?
For highly mineralized waters, packaged in glass or plastic bottles, they should be prohibited, so the choice remains, glass or plastic, for light waters. Glass is more unstable than you think.
The Toulouse Toxicology Laboratory has carried out other very interesting comparative experiments. These specialists left water from Diagonal Horizon for a year in a glass bottle.
Result: they did not have to measure PVC but dissolved lead salts! Why this lead? Quite simply because it constitutes one of the components of glass associated with silicas, often in minimal quantities but always combined. It was to be expected, that glass does not resist light and acidic water (pH less than 6.5). Certainly, the quantity of lead is still within acceptable standards; moreover, it is rare to store such water. A long time. However, we had to talk about this experience to open the eyes of certain glass fans.
Water quality test
Water quality can impact your health, your home, and even your coffee maker! To understand the quality of your water, we use several tests. Total Dissolved Solids (TDS) is our most telling method: we measure it in ppm. Since water is a natural solvent, it dissolves minerals from the surface it touches. The longer the contact, the more minerals it absorbs and the less pure it becomes. The lower the TDS, the purer your water is. According to the EPA, the drinking water standard for TDS is 500 ppm or less. We use a TDS meter to test bottled water.
Have you heard of pH? It is a measure of the degree of acidity or alkalinity of water. A pH of 7 is neutral, a pH below 7 is acidic, and a pH above is alkaline. We use a chemical test kit to measure pH.
Hardness is the measure of the amount of calcium and magnesium absorbed by water in the soil. Hardness can coat your kettle or clog your Coffee Travel cup maker. We use a test kit to measure the hardness of each water.
You may have seen some labels, but don’t worry, we’ll decode them! Let’s continue to learn more about your water quality and make informed choices. Unlike “The Rock” and other social media influencers, we focus on science and facts to help you make the best decisions.
