Because they are such common disinfectants, some chlorine and chloramine are usually present in drinking water. And it is generally safe to consume the disinfectants in small doses. So, is it safe to drink tap water that smells like that smells like bleach or chlorine? Not necessarily.
When your water starts smelling like a pool, it’s a warning sign that your water could be overchlorinated. And anything over the EPA recommended limit of 4 mg/L and even slightly under it could lead to serious health problems. Such health issues include bladder, rectal and breast cancer. Overconsumption of chloramine can also cause digestive problems, respiratory issues and mouth ulcers. So, beware of a chlorine smell in your water.
Chlorine and chloramine can also create harmful byproducts during the disinfection process. These byproducts include trihalomethanes (THMs) and haloacetic acids (HAAs). Consuming THMs can lead to cancer and congenital disabilities, and HAAs can cause cancer, liver and kidney problems.
On top of this, the disinfectants can also dry out your skin and hair after bathing and corrode household plumbing fixtures over time. This corrosion can lead to excessive stains on clothing and dishware—meaning, you might have to wash your dishes again or rewash a load of laundry.
