Here's why:
* Disinfection: Chlorine is a powerful disinfectant that kills harmful bacteria and viruses in the water supply. This is essential for preventing waterborne illnesses.
* Cost-effectiveness: Chlorine is relatively inexpensive and easy to use.
* Residual Protection: Chlorine remains in the water as it travels through the distribution system, providing ongoing protection against microbial contamination.
Other chemicals that may be added to water include:
* Fluoride: Added to strengthen teeth and prevent tooth decay.
* Calcium and magnesium: Added to correct for hard water, which can cause scale buildup in pipes and appliances.
* Sodium: Added in small amounts to control corrosion in the distribution system.
* pH adjusters: Added to ensure the water is within a safe pH range.
The specific chemicals added to your water will vary depending on your local water treatment facility and the quality of the source water. You can contact your local water utility for more information about the specific chemicals they use and the levels at which they are added.
