If the water has changed color or smell, be careful! Doctors called several signals that the water is unfit for drinking.
Comments of experts about what signs can talk about the unsuitability of water for drinking, published Business Insider, quotes MedicForum. The experts have compiled the following list.
Turbidity. Turbid water, according to researchers, can speak about the external chemical elements contained in it, which can be toxic to the body.
Yellowness. Obviously a yellow hue of water is a signal that the liquid is supersaturated with iron, copper, lead and manganese.
Green shade. It may indicate an excess of copper.
Rigidity. Increased water hardness is a sign of increased magnesium and calcium concentrations.
Rotten smell. This is a sign of saturation of water with hydrogen sulfide.
Fish smell. It occurs due to the large amount of barium in the water.
A recent study by American scientists from the Environmental Working Group, published in the journal Environmental Health, showed that tap water may contain carcinogenic pollutants for the human body, such as arsenic, hexavalent chromium, radioactive uranium and radium.
On the subject: US residents can find out the composition of their tap water through a zip-code.
Under the influence of these substances develop oncological diseases. Researchers said that about a third of the estimated cancer diagnoses may be related to the side effect of the chemicals that treat tap water.
