Pure Water in Your Green Kitchen
Pure Water for Good Health
We all want pure water in our homes.
We often take if for granted that the water from our taps is safe to drink. Domestic water supplies have been fairly safe to drink for more than a century in most developed nations. So perhaps many people do not see it as an issue.

But there are some health problems associated with tap water.
In this article we look at the safety of tap water and other drinking water, and what we can do to improve it. There is also some information on the issue of bottled water.
Pure water - why is it so important?
Pure water is so necessary for good health.
The human body is about 70% water, our brains are 85% water, our blood is about 90% water and our livers are also very largely composed of water! The liver is the chemical factory of the body and is one of our most vital organs. It is responsible for coping with all the toxic materials that we and the environment throw at it.
Our kidneys, too, play a vital role in detoxifying our systems.
Water is a key element in keeping these systems functioning properly.
So it's quite logical to believe that the quality of the water we drink will have a big effect on our health.
Pure water - the purification process
Water from your tap has had a long journey.
The water that you sip today in your tea, or that sits clinking in your glass as ice, has travelled many miles through a complex network of reservoirs, pipes and filtration systems.
It has also undergone a lengthy process of purification which is designed to make it safe to drink.
So just how safe is tap water?Can we class it as "pure water"?
The purification of water is highly effective for the most part. Most common pollutants are effectively filtered out. For example it is rare for tap water to be a source of harmful bacteria.
Water purification is expensive. The United States, for example, is needing to invest 150 billion dollars to keep water purity at acceptable levels.
Water in most developed nations is purified to a very high standard.
However there are a number of chemicals which can find their way into drinking water supplies, despite the hard work of the water companies.
There are so many man-made chemicals in our environment these days that it is perhaps not surprising that we have difficulty in keeping them out of water supplies. Scientists estimate that each year up to 7 million Americans become sick from drinking contaminated tap water.
The Environmental Protection Agency claims that that over 2100 cancer-causing chemicals have been detected in American water supplies.
Here in the UK nitrates from agriculture are a persistent problem.
So what pollutants can affect drinking water?Tap water can contain synthetic chemicals, heavy metals, parasites and chlorination by-products.
Below are some of the commoner examples of chemical pollutants found in domestic water supplies.
