Drinking Water Chlorination Is the Addition of Chlorine to Drinking Water Systems
Chlorine is a highly effective method of disinfection. However, while in the pipes it produces small amounts of chemicals if the source water has higher levels of dirt or germs that may react with chlorination. Chlorination is the most widely used disinfectant for municipal wastewater because it destroys target organisms by oxidizing cellular material. Chlorination gas, sodium hypochlorite, and calcium hypochlorite are common types used in water treatment. Water chlorination is the process of adding chlorination or chlorination compounds.
Chlorination involves adding a measured amount of chlorine or chlorine compounds to water to produce a residual sufficient to kill bacteria, viruses, and cysts. Chlorine Market can be applied for the deactivation of most microorganisms and it is relatively cheap. Thus, it is one of the most commonly used disinfectants for water disinfection. Chlorination levels up to 4 milligrams per liter (mg/L or 4 parts per million (ppm)) are considered safe in drinking water. At this level, harmful health effects are unlikely to occur.
Studies have also indicated that using or drinking water with small amounts of chloramine does not cause harmful health effects and provides protection against waterborne disease outbreaks. The U.S. Environmental Protection Agency (EPA) limits the amount of chlorination in drinking water to levels that are safe for human consumption. The levels of chlorination used for drinking water disinfection are unlikely to cause long-term health effects. Due to the low concentration of chlorine in water supplies, drinking chlorine-contaminated water is not of grave concern.
The EPA has also officially stated that chlorinated drinking water is safe to consume, as long as the chlorination levels are properly managed. Many public water systems add Chlorine to water supply for the purpose of disinfection. Disinfection kills or inactivates harmful microorganisms which can cause illnesses such as typhoid, cholera, hepatitis and giardiasis. According to the U.S. Centers for Disease Control and Prevention (CDC), chlorine is one of the most commonly manufactured chemicals in the United States.
