Somehow, the idea that tap water is unclean is at the back of your mind. Sure, you have been warned about it before but do you have any idea just how dangerous water filtration solutions can be to one’s health? Tap water and the incredulous dangers it poses have been studied and documented over the last few decades. Now, those who are in charge of those studies admit that tap water, sadly, is of the exact quality as wastewater. Yes, it’s that bad.

 

The danger actually varies depending on where you live. For example, if you live in a city, most likely, your tap water comes with loads of birth control pills, antibiotics, antidepressants, and other pharmaceutical drug residues. With all that, is it a wonder that antibiotic-resistant bacteria pop-up on a regular basis?

 

A study has also shown that about 43, 381 viruses have been found in sewer systems, some of which are actually unknown to scientists. What is more bothersome is the fact that this sewage system is turned into some tap water after being touched by chemicals that include chlorine. That means that tap water could actually be breeding an indefinite amount of deadly viruses, too.

 

In addition to this, there is also a threat that comes from the presence of sodium fluoride in tap water. Significant studies have also discovered that the level of fluoride that is found in tap water could affect IQ and possibly lead to permanent damage too. It may also be causing thyroid issues that later on lead to depression and other more serious conditions.

 

Thankfully, more and more areas are into ending fluoridation of public water supplies locally. This is, however, not enough. To make sure that your family is safe from the harms brought by tap water, it is advisable that you get water treatment system installed.

 

Many people make a conscious effort of buying bottled water to drink, without realizing that possibly dangerous water is still affecting their health through their showers and baths. Most homeowners fear that these water treatments are expensive when actually, they are less costly than you probably think.
