0

If the water has changed color or smell, be careful! Doctors have named several signals that water is unfit for drinking.

Experts' comments on what signs may indicate that water is unfit for drinking. Experts have compiled the following list:

Turbidity. Turbid water, according to researchers, may indicate foreign chemical elements contained in it, which may be toxic to the body.

Yellowness. An obvious yellow tint of water is a signal that the liquid is oversaturated with iron, copper, lead and manganese.

Green tint. It may indicate an excess of copper.

Hardness. Increased water hardness is a sign of an increased concentration of magnesium and calcium.

Foul odor. This is a sign that the water is saturated with hydrogen sulfide.

Fish odor. It occurs due to a large amount of barium in the water.

A recent study by American scientists from the Environmental Working Group showed that tap water may contain carcinogenic pollutants for the human body, in particular, arsenic, hexavalent chromium, radioactive uranium and radium. Under the influence of these substances, oncological diseases develop. Researchers stated that about a third of the alleged cancer diagnoses may be associated with the side effect of the chemicals used to treat tap water.
