Customers in and around the Hiddenbrook area of Fairfax County, VA, can now use tap water for all purposes without boiling prior to use. The boil water advisory is lifted. Water quality samples collected over the past two days confirm that the water meets regulatory standards. Customers should flush their cold water taps for approximately 5 minutes and discard out any ice in ice makers before allowing it to refill.
On Saturday and Sunday, water samples were collected in the impacted area for bacteriological testing and to monitor chlorine levels. All results show that water in the impacted portion of the system meets regulatory standards. Fairfax Water has been working with the Virginia Department of Health’s Office of Drinking Water throughout this advisory, and they have been notified of the testing results.
On November 13, 2021, Fairfax Water issued a boil water advisory for customers around the Hiddenbrook area of Fairfax County, VA, due to a valve failure that resulted in a loss of pressure to a portion of its distribution system. Customers in other areas of Fairfax Water’s system and customers served by the Town of Herndon were not impacted. The boil water advisory was issued out of an abundance of caution due to a loss of pressure in the system, not due to a water quality issue. Additional information is available on Fairfax Water’s website: www.fairfaxwater.org.
Fairfax Water appreciates its customers’ patience and is available to answer any customer questions on this matter. Customers with questions may call Fairfax Water at 703.698.5800 (TTY 711) or email customers@fairfaxwater.org.
