Water, like any other substance, can be considered a poison when over-consumed in a brief period. Water intoxication mostly occurs when water is being consumed in a high quantity provoking disturbances in electrolyte balance. [2] Excess of body water may also be a result of a medical condition or improper treatment; see "hyponatremia" for some ...
Rolling boil of water in an electric kettle. Boiling or ebullition is the rapid phase transition from liquid to gas or vapour; the reverse of boiling is condensation.Boiling occurs when a liquid is heated to its boiling point, so that the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
First known science-based boil-water advisory (1866) John Snow's 1849 recommendation that water be "filtered and boiled before it is used" is one of the first practical applications of the germ theory of disease in the area of public health and is the antecedent to the modern boil water advisory. Snow demonstrated a clear understanding of germ ...

The proponents of raw water praise the fact that it doesn't contain chemicals like chlorine, fluoride or chloramines -- but that might not be a good thing. Why that ‘raw water' trend is actually ...
Surface and ground water stagnation; Trapped water stagnation. The water may be trapped in human artifacts (discarded cans, plant pots, tires, dug-outs, roofs, etc.), as well as in natural containers, such as hollow tree trunks, leaf sheaths, etc. To avoid ground and surface water stagnation, the drainage of surface and subsoil is advised.
Superheating can occur when an undisturbed container of water is heated in a microwave oven. At the time the container is removed, the lack of nucleation sites prevents boiling, leaving the surface calm. However, once the water is disturbed, some of it violently flashes to steam, potentially spraying boiling water out of the container. [6]
