What country does not use chlorine?
The Netherlands is one of the few countries where chlorine is not used at all, neither for primary disinfection nor to maintain a residual disinfectant in the distribution network.
In Europe, most drinking water production companies use chlorine as a disinfectant. It is added to water as chlorine gas, calcium hypochlorite or sodium hypochlorite. Ozone is added for flavor and odor control. For drinking water preparation from surface water, chlorine is used as a primary disinfectant in most cases.
The cause of this smell is chlorine. In Japan, salt is contained to disinfect tap water. With the use of chlorine the germs are disinfected and you can drink fresh water, but on the other hand, the tap water might smell a bit like chlorine.
1. Switzerland: With strict treatment standards and superior natural resources, Switzerland ranks number one for best EPI. In fact, Swiss tap water is as pure as its bottled water – but 500 times cheaper.
Without chlorine, life as we know it could not exist.
One way to think about this is examining table salt. Table salt is half negatively charged chlorine and half positively charged sodium. It's important for a living thing to balance its charge and one of the easiest ways to add negative charge is through chlorine.
The level of chlorine in tap water is very low in England and Wales which contrasts very favourably with practices in other countries where much higher levels are common. Typically, water companies keep the level of residual disinfectant in the form of free or combined chlorine to 0.5 mg/l or less.
Italy and Germany use ozone or chlorine dioxide as a primary oxidant and disinfectant. Chlorine is added for residual disinfection. Great Britain is one of few European countries that use chloramines for residual disinfection in the distribution network and for the removal of disinfection byproducts.
In the UK, all public water supplies must be disinfected by law to destroy any bacteria which may be harmful to your health. Predominantly, chlorine is used to ensure your water is safe to drink and meets our quality standards.
Distilled water is a type of bottled water that has been completely purified and contains no minerals or chemicals of any sort. Water that is sold in fountain machines at supermarkets is often distilled or purified in other ways, and is free of chlorine, fluoride, minerals, or bacterial contaminants.
Can I swim in water without chlorine?
Even from a health standpoint, it is simply not safe to operate a pool without some added “chemicals” to combat bacteria and contaminants in the water. A pool without chemicals is the perfect breeding ground for bacteria, viruses, and parasites.
Spring water
If you're looking for clean, great-tasting water, this is generally a popular choice. Spring water naturally contains minerals and possibly beneficial bacteria, without chemicals like chlorine or fluoride.

Evian is our number one choice - the top tasting bottled water of our time! It is sourced in the Évian-les-Bains town in France and it delivers a mesmerizing experience that's hard to forget.
Again, the healthiest water to drink is water that's free of pathogens and contaminants, yet rich in key minerals. But, if there was one water option to pick, it's likely going to be spring water or clean artesian water—water that still contains healthy mineral content and is free of pathogens.
Exposure to low levels of chlorine can result in nose, throat, and eye irritation. At higher levels, breathing chlorine gas may result in changes in breathing rate and coughing, and damage to the lungs. Additional symptoms of exposure to chlorine can be severe. Workers may be harmed from exposure to chlorine.
When chlorine enters the body as a result of breathing, swallowing, or skin contact, it reacts with water to produce acids. The acids are corrosive and damage cells in the body on contact.
Chlorine is the 19th most common element in the earth's crust, at a prevalence of 1.45 x 102 milligrams per kilogram. In the ocean, chlorine is the third most common element, at a prevalence of 1.94 x 104 milligrams per kilogram of water.
Chloride is found in table salt or sea salt as sodium chloride. It is also found in many vegetables. Foods with higher amounts of chloride include seaweed, rye, tomatoes, lettuce, celery, and olives.
Free chlorine kills most bacteria, such as E. coli 0157:H7, in less than a minute if its concentration and pH are maintained as CDC recommends. However, a few germs are moderately (Giardia, Hepatitis A) to very (Cryptosporidium) chlorine tolerant.
Chlorine poisoning can cause symptoms throughout your body. Respiratory symptoms include coughing, difficulty breathing, and fluid inside the lungs. Digestive system symptoms include: burning in the mouth.
Does the UK use chlorine in water?
In the UK, all public water supplies must be disinfected by law to destroy any bacteria which may be harmful to your health. Predominantly, chlorine is used to ensure your water is safe to drink and meets our quality standards.
Most drinking water treatment plants in Canada use chlorine as a disinfectant. The use of chlorine in the treatment of drinking water has virtually eliminated waterborne diseases, because chlorine can kill or inactivate most microorganisms commonly found in water.
The Australian Drinking Water Guidelines (external site) requires that the level of chlorine in drinking water should not exceed 5 milligrams per litre (5 parts per million). For more information on the chlorine level in your drinking water supply, please contact your local water supplier.
In France, 95% of people are supplied with chlorinated tap water. Due to the presence of natural organic matter that reacts with chlorine, the concentrations of chlorination by-products (CBPs) are much higher in chlorinated water produced from surface water than from groundwater.
