Identify one way to effectively reduce lead in drinking water.

Using water filters that are certified to remove lead is an effective method for reducing lead in drinking water. These filters are specifically designed to target and trap lead particles, which may leach into drinking water from lead pipes or plumbing fixtures. The certifications ensure that the filter meets established standards for lead reduction set by organizations such as NSF International or the Water Quality Association.

While boiling water can kill pathogens, it does not effectively remove lead and might actually concentrate it, making it an unsuitable option for lead reduction. Adding chlorine to the water supply may help in disinfecting the water but does nothing to eliminate lead. Relying solely on bottled water may alleviate exposure in the short term, but it is not a practical long-term solution for ensuring clean drinking water throughout the home. Thus, the use of certified water filters is the most direct and sustainable method for mitigating lead exposure in drinking water.
