The Difference Between Tap Water and Distilled Water

Water Drop by soulmuser, on FlickrIt’s a sad fact to face, but not all water on Earth is clean. Sometimes, there are clear signifiers that show us whether the water is clean or not; signifiers such as pollution, a scummy foam, or the presence of insects on the water’s surface. But what if the seemingly clear and “clean” water running from your tap is not as clean as you think?

We review the difference between distilled water and regular tap water, so that you can understand why distilled water is the preferred water of choice for companies involved in chemical manufacturing, medicines, syrups and other industries.

Tap Water

The water that pours through the taps of your home or office, can broadly be defined as the water the local authorities deem safe to drink. And while in most developed countries, this is indeed the case, this cannot be guaranteed. Drawn from natural reservoirs, the regular tap water is rendered “safe to drink” after undergoing various treatment and water treatment plants. This means that the water running from your tap can contain trace amounts of the chemicals that are used to treat it, such as fluoride, microorganisms and nitrates. In this way, it’s the government that regulates the purity and content of your tap water, meaning its ‘drinkability’ will fluctuate from place to place.

Distilled Water

Distillated water is water that has undergone a process of purification called distillation. This process removes nearly all contaminants from the water by boiling it in a container with a curved lid that extends beyond the container. The steam of the boiled water condenses on the lid and runs off into a second container. The distillation process ensures that contaminants are left in the boiling vessel, which results in a cleaner and more pure water in the collection vessel. That’s why distilled water is the water of choice when the process requires a water of an absolute known quality that is pure and clean.

Having explored the difference between distilled water and regular tap water, it is clear that distilled water doesn’t contain any impurities, whereas tap water does. And because we can’t be certain what chemicals water treatment plants are using to treat their tap water, or whether there remain traces of it in the water that comes out of our taps, it’s clear why distilled water is used in the processes that it is used. The purity and cleanliness of distilled water remains constant no matter where you get it from, because of the process it has undergone.
