The Taste Test Challenge: District Residents Reveal No Preference in Bottled or Tap Water

September 20, 2010

Many people think local tap water tastes better than bottled water, or are simply unable to identify a taste difference between the two, according to the District of Columbia Water and Sewer Authority. DC Water recently encouraged District residents to participate in a series of blind taste tests comparing tap and bottled water. The DC Water Taste Test Challenge also highlighted the benefits of drinking tap water.

“We encourage everyone to consider the type of water they drink at home and understand that tap water is a good choice,” said DC Water General Manager George S. Hawkins. “Everyday, DC Water is monitoring and testing local tap water to ensure its high quality, so that our customers can avoid the financial and environmental costs of purchasing bottled water.”

Most recently, the DC Water outreach staff hosted a taste test challenge at the Penn Branch Department of Motor Vehicles service center, 3220 Pennsylvania Avenue, S.E. Participants were surprised to learn that tap water tasted better than bottled water, yet, many reported using bottled water instead of tap water for cooking and drinking at home.

District drinking water meets strict federal regulatory standards, with test results available online and mailed to every resident. At about a penny a gallon, it is also much more affordable than bottled water – while requiring no packaging to dispose or recycle. Taste tests conducted throughout the District enabled DC Water to learn more about public perceptions of local tap water and proactively respond to questions about drinking water quality.

DC Water continues to educate the public about the value of local tap water. Customers are encouraged to contact the Water Quality Division at (202) 612-3440 or visit www.dcwater.com if they have questions about their tap water. After hours, customers may call the 24-hour Emergency Call Center at (202) 612-3400.
