Is Chlorine Water Safe to Drink?


When you think of the chemical chlorine, perhaps you think of swimming pools, paint, or cleaning products. But chlorine also exists in the water you use to bathe, clean, and hydrate. When present in water, it is often referred to as chlorinated water. Worried how it can affect your health? Here’s everything you should know about chlorine in your home’s water supply.

Does Your Home Have Chlorinated Water?

If you’re unsure about the elements in your water, it may be time to look. For a general synopsis of your water’s health, check the EPA’s yearly Consumer Confidence Report. Discover where your water is coming from and what impurities are hiding within it. For more precise results, get started with a free in-home water test from Culligan. Results will reveal whether your water has any traces of chlorine, heavy metals, and other impurities that can put you in danger.

Why Is There Chlorine in Water?

Chlorinated water is nothing new. In fact, it’s been around since the early 1900s and arose as a medical breakthrough. At the time, waterborne diseases like cholera, typhoid fever and hepatitis were taking the lives of thousands of Americans. To combat the devastation, water distributors turned to chlorine, which reduced the harmful bacteria causing these illnesses. After much success in these efforts, chlorine continues to provide an affordable and sizable solution to disinfecting water supplies around the nation.

So, how does chlorine disinfect the water? It attacks the cell membrane of harmful bacteria. In turn, chlorine suspends cell respiration and DNA activity – both of which are required for bacteria’s survival. The process of chlorination occurs during the first and final step of the water treatment process. When water first enters a treatment facility, chlorine can help eliminate aquatic life like algae and weaken elements like iron and magnesium. At the end of the process, chlorine helps to disinfect the water and ensure enough chlorine is present to survive throughout the distribution process. Depending on your water’s treatment facility, different levels of chlorine may be found in your water supply.

Is Chlorine Water Safe to Drink?

With water treatment plants readily adding this chemical to local water supplies, many homeowners are left wondering – is drinking chlorinated water harmful to your health? Due to the low concentration of chlorine in water supplies, drinking chlorine-contaminated water is not of grave concern. That said, chlorinated water may taste and smell like bleach or chemical residue. The potency of these effects may vary depending on your home’s proximity to the water treatment center.

What Can You Do to Lower Chlorine in Drinking Water?

To lower chlorine in your drinking water, you’ll need to remove the chemical from your water supply. Water filters like Culligan’s Water Filtration Systems do the hard work for you while providing your whole home with total protection. With an all-in-one water filter, you can get cleaner, fresher, better-tasting water from every faucet in your home with ease.
