Quick Answer
Long-term use of chlorine in drinking water has been linked to several health concerns, including increased risk of bladder cancer, reproductive issues, and thyroid problems.
Health Risks Associated with Chlorine
Chlorine is a widely used disinfectant in drinking water treatment. However, its use has been linked to several health risks, including bladder cancer, reproductive issues, and thyroid problems. The World Health Organization (WHO) recommends a maximum allowable concentration of 5 milligrams per liter (mg/L) of chlorine in drinking water. However, even at this concentration, long-term exposure to chlorine has been shown to pose significant health risks.
Chlorine Exposure Limits and Guidelines
The Centers for Disease Control and Prevention (CDC) recommends a maximum allowable exposure limit of 0.5 milligrams per kilogram (mg/kg) of body weight per day for chlorine. To put this in perspective, a 154-pound (70 kg) person would need to consume more than 35 mg/L of chlorine in their drinking water to exceed this limit. However, it’s essential to note that these guidelines are based on short-term exposure, and long-term exposure to even low concentrations of chlorine may still pose health risks.
Safe Alternatives to Chlorine Disinfection
Fortunately, there are safe and effective alternatives to chlorine disinfection. Ultraviolet (UV) light disinfection is a popular alternative, as it is effective against a wide range of bacteria, viruses, and protozoa. According to the Environmental Protection Agency (EPA), UV disinfection can be up to 99.99% effective against bacteria and viruses. Additionally, ozone disinfection is another alternative that is effective against a wide range of microorganisms.
