Do you think that bottle of water that you are drinking is pure water without the contaminants that might be found in tap water? If so, you are wrong. Bottled water is one of the reasons for ill health. The water is as clean as where it came from. That is to say if it came from a bottling plant that the safety and cleanliness procedures were not followed as stringently as they should have been, this water is probably not as clean as your tap water.

The presence of contaminants in your drinking water does not necessarily mean that you are going to become sick. But if surface water, such as a river is the source of your water, it could have been vulnerable to acid rain, pesticide runoff, and dumping from industrial plants. The air, sunshine, and some types of micro-organisms can be a sort of cleansing agent but not entirely.

The bad thing about effects from exposure to contaminants in water is that they are more chronic problems than immediate. Some of these diseases may include cancer, liver damage, kidney damage, and birth defects.

Certain water requires a longer time to become totally free of the contaminants that are being removed. The chemical that is being used to sanitize the water is not always used in the right concentration or it is not left in the water long enough to work properly. Another consideration is temperature. Certain chemicals only work correctly under certain temperatures. Which means that in certain instances your water may not be sanitary at all.

If your water comes from a well or from a source that supplies public water, it does not become contaminated as quickly. On the other hand, it does not go through the natural cleansing as quickly either. Pathogens, liquid waste from septic tanks and garbage dumps, or storage tanks underground may leak into the underground water. So even if you think well water is purer than most, you may not be drinking as pure water as you think.

Research has shown that our water, whether it comes from a well or from a municipality is not as safe as it once was. The contaminants that are becoming more prevalent in today's world are slowly making their way into the air we breathe and the water we drink. Chemicals are one of the contaminants that have found their way into our drinking water. Even chlorine has been found not to be a disinfectant that we want in our drinking water.

A filtration system can help to clean the water you drink and remove anything that can have adverse effects on the body. When you think about it, water is something that we use constantly without even thinking about it. In order to have the highest quality water that you can have, a filtration system is necessary.
