When I turn on the hot water, the water comes out cloudy... Is it okay to use it for cooking? Reporter Hae-rim Lee's story.

As the weather gets colder, I find myself using hot water more often. I turn the faucet on and turn on the water, but the water comes out cloudy. Could there be a problem with the water quality?

 

Cloudy warm water is caused by "white water." This is caused by air entering the water, and has nothing to do with water quality.

 

Air flowing into the pipes leading from the water purification plant to the home is subjected to intense pressure, breaking down into tiny bubbles. These finely broken bubbles easily dissolve when they come into contact with hot water. These tiny bubbles, dissolved in the water, reflect diffusely, making the water appear cloudy.

 

The water quality is not bad, so you can shower in it and even drink it.

If you pour water over it and let some time pass, bubbles will rise to the surface and the water will become transparent again.

The problem is that cold water looks cloudy. Oh It is possible that zinc from the old pipes was mixed in.

 

Unlike other heavy metals, zinc dissolves in water and becomes cloudy. While consuming it as a nutrient can boost immunity, long-term exposure to heavy metals can lead to poisoning and chronic illness. Therefore, the use of galvanized steel pipes in water pipes has been banned since 1994, but they still persist in older water and sewer systems.

 

If you are concerned about water quality, you can use the ‘Tap Water Safety Check System.’

 

If you go to the internet homepage 'Water Love Nurijip' and apply for a water quality test, a local government official will visit you, collect tap water, and request a water quality test from a water quality testing agency.

 

First, ▲turbidity ▲residual chlorine ▲hydrogen ion concentration (pH) ▲iron ▲copper ▲zinc levels are tested, and if any item exceeds the standard, a second test is conducted. At this time, ▲general bacteria ▲total coliform group ▲chlorine ion ▲ammonia nitrogen ▲manganese ▲pigment ▲hardness, etc. are added to the first test items.
