There can be many problems for a homeowner, some of which stem from the water supply. We want the water carried into our homes to be of the best possible quality, just as it is at its source e.g. from the mountains.
However, the quality of our water supplies, especially in certain areas, certainly leaves a lot to be desired. Although measures are in place to improve quality parameters, there are some factors, such as the presence of certain pollutants, which cannot be fully resolved.
Some of these factors are significant and have given rise, in specific regions, to an official limitation on certain uses of tap water. There are some areas, for example, with high levels of arsenic in their water and other agricultural areas where the tap water may contain nitrates or pesticide residues.
Other times, the main water supply may contain pollutants but regulations state that this water can be used as long as set concentration levels are not exceeded e.g. for pesticide residues or trihalomethanes. In any case, the lack of general access to data on the chemical contaminants in our drinking water, as well as doubts regarding the health implications from exposure to these levels, has raised suspicion.
There are, in the home, many factors which can contribute to the presence of pollutants in our water, which may or may not be resolvable. Sometimes we can do something about these factors; other times it is much more difficult.
You could, for example, find out what your pipes are made of and try and change them for less harmful materials e.g. stainless steel, stone, clay etc. If you use plastics, at least make sure that the ones you use are not known to have adverse health effects.
Among the many basic preventative measures which can be taken to stop the unnecessary ingestion of various pollutants which build up in our water pipes, you can leave the water running for a few moments before consumption.
Another option which is yet to be properly assessed is to install water purifiers. These are filters which can reduce the presence of some chemical pollutants in our water. However, these processes (activated carbon, inverted osmosis and distillation) need to be investigated further, as well as their advantages and disadvantages e.g. the possible wastage of water, the generating of ozone, sufficient or insufficient purification etc.
