Fairfax Water Authority Begins Regional Flushing Effort

The Fairfax Water Authority that provides the City of Falls Church with its water services started its annual flushing program this week. In a statement, it announced that Instead of its usual practice of disinfecting the supply with chloramine, it will temporarily stop adding ammonia to drinking water in an effort to maintain the system’s quality.


The Environmental Protection Agency, which regulates utility chemical levels, says both chlorine and chloramine disinfectants are safe to drink and help kill germs.


Fairfax Water offered suggestions to handle the changes in drinking water:


“You may notice a chlorine taste and odor in your drinking water while free chlorine is utilized. If you are especially sensitive to the taste and odor of chlorine, try keeping an open container of drinking water in your refrigerator. This will enable the chlorine to dissipate, thus reducing the chlorine taste. Remember – drinking water has a shelf life! Change out the water in your refrigerated container weekly.”


The flushing period will last through June 13 for most of Fairfax County. McLean, Merrifield, and nearby areas will have the process end on May 9.
