A diagram of the hydrological cycle by which water falls to the earth and rises back again

As human beings, water is an essential part of our daily lives. Not only do we need to drink it on a daily basis – a healthy person can survive only a week without it – but it literally makes up 70% of our bodies on average.

Of all the water on earth, 97% of it is undrinkable salt water. About 3% of it is fresh water, most of which is frozen and locked in the polar ice caps and glaciers. Only 1/2 of 1% of all fresh water is underground and about 1/50th of 1% of all water is surface water in lakes and streams.

Water of all types evaporates from the Earth and rises into the atmosphere where it forms clouds. This is part of the hydrological cycle, which is the scientific name for water’s natural transition from liquid to vapor and back again. Water in the clouds is in its purest form, but it does not stay that way for very long.

Water droplets forming in clouds absorb particles and impurities found floating in the air. Water has a tendency to dissolve a little bit of everything it touches including industrial smoke, dust, carbon dioxide, spores and smog.

The water vapor in clouds eventually condenses and falls back to earth as rain, sleet, hail or snow. Before water makes its way to your home, it has the opportunity to pick up any number of impurities and contaminants.  The contaminants found in water depend in part on where it comes from – the surface, or underground. Surface water, found in rivers, lakes or surface impoundments, is typically not high in mineral content, but is likely to contain animal wastes, pesticides, insecticides, industrial wastes, algae and organic matter.

Once water seeps down into the ground and becomes trapped beneath the surface, it is considered ground water. Ground water, while being at risk for many of the same contaminants found in surface water, is also very likely to dissolve some of the minerals it comes into contact with during its passage underground. Minerals like calcium and magnesium are the primary causes of hard water.

Modern technology provides us with the means to combat each of these potential issues. Today’s water softeners are highly effective and efficient in removing dissolved minerals from the water before you use it in your home, saving you from the hassle of soap scum and staining. Purifiers can use anything from ultraviolet wavelengths to reverse osmosis technology to eliminate bacteria, sodium, iron, and any other dissolved solids that could make their way into your water. At Water Doctors, it’s our goal to remove all the excess minerals and impurities and provide you with the water you deserve.
