Water is the key to life. The human body consists of approximately 70 percent water. And this already confirms what was said above. But do you know why water is called water, as well as the origin of other names associated with this transparent, vital liquid.
Origin of the name "water"
Despite the fact that water is the key to life on our planet, etymologists still do not agree on the origin of this word and the name itself. We can only say that water can have its roots in the Proto-Slavic language, where there was a word such as “vodā”.
As for the origin of this name, some sources believe that since ancient times, any liquid used as drinking began to be called water. This name has been retained for H2O to this day.
Why is wastewater called wastewater?
Of course, most people have heard of the term wastewater. It is clearly not recommended to use such liquid as a drink, because this term refers to contaminated water, which can be saturated with all kinds of waste. The liquid got its name from the word “Drains”.
Why is water called fresh?
As you know, water can be either sea or fresh. And if we talk about sea, salty water, then its name is quite obvious and logical, because salty water is characteristic of the seas (and some large lakes).
As for fresh water, it was so named due to the almost complete absence of taste.
Of course, when we are thirsty, a sip of fresh, cool water seems to us much tastier than any delicacy, but in reality it is fresh, and received its name due to its similar, barely perceptible to humans, taste qualities.
Why is artesian water called artesian water?
Many of us have noticed a mark on mineral water stating that it is obtained from artesian springs. And there is also a rational explanation for this name. This name was given to the water in honor of the French province of Artois, where in the 12th century they began to use water extracted between water-resistant underground layers.
Today, this is the name given to water extracted from sources located below the groundwater level, at a depth of 100 to 1000 meters. Typically, this is the kind of water used by manufacturers for sale in plastic containers with a volume of 0.3-0.5 liters and above.

In an effort to protect themselves from various infections contained in “raw” water, many drink bottled water. However, is this replacement actually advisable? As scientists' research shows, not quite.
In 2015, the Moscow State University analytical center conducted large-scale laboratory research, during which 20 samples of bottled water from well-known brands and 28 from more modest brands were studied. 4 samples out of the last 28 turned out to be undrinkable. In them, experts found increased alkalinity and a huge number of bacteria. One sample out of these 4 was rejected due to poor, but already useful microflora. This result, according to the center’s specialists, is explained by thorough cleaning, thanks to which both the harmfulness of the water and its benefits were reduced to zero.
Water from well-known brands upset the researchers even more: 6 samples out of 20 were immediately rejected based on microbiological indicators. The number of bacteria forming colonies in the samples turned out to be 1.5-2 times higher.
Everyone knows that water is most often sold in plastic containers, for the production of which, as American scientists have found, the harmful chemical bisphenol-A is used. This substance negatively affects reproductive function, the activity of the thyroid gland and the central nervous system. Bisphenol-A is actively released from plastic into water at above-zero temperatures. In 95% of the experiment participants, bisphenol-A was detected in the urine after drinking bottled water. German scientists who published the results of their work in the publication PLoS ONE came to the same conclusions.
