DC Tap Water Defeats Bottled Water in Blind Taste Test

September 05, 2013

Washington, DC – The results are in! During DC Water’s blind Taste Test Challenge, 63% of participants preferred the taste of tap water to bottled water or could not taste the difference.

This summer DC Water conducted a series of taste tests in each of the District’s eight wards. Close to 600 participants tasted unmarked water samples and answered questions about the type of water they drink at home. Many residents, including those that said they drink bottled water at home, were surprised to learn that they preferred the taste of tap water over bottled water. The results mirrored the data collected during similar tests in 2012.

“The taste tests are an excellent way for customers to learn more about the affordable, high-quality product that is delivered to their homes every day,” said DC Water General Manager George S. Hawkins. “And most importantly, the results show that that our tap water is delicious. Why pay more for bottled water that doesn’t taste as good?”

Some participants were shocked to learn that bottled water costs 100 to 1,000 times the price of tap water. At a little more than one penny per gallon, tap water is also an eco-friendly choice. Bottled water production requires large amounts of oil and water, and disposable bottles contribute to landfill waste and pollution in the environment.

In addition, DC tap water meets much stricter water quality standards than bottled water, and DC Water collects hundreds of samples each week to ensure the delivery of high-quality tap water throughout the District. For customers who still aren’t convinced, DC Water offers free water quality testing. To schedule an appointment, customers can contact the Drinking Water Division at 202.612.3440.

DC Water also partners with local businesses in the TapIt program which allows anyone to refill their reusable water bottle for free at any TapIt location in the DC area. For more information about TapIt and the free TapIt Metro DC phone app, please visit www.tapitwater.com/dc.

Trench boxes at construction site for new pit accessing Potomac Interceptor Upstream

DC Water and its contractors continue to make progress constructing new access points to the Potomac Interceptor, one upstream of the damaged section, and an additional entry downstream to divert more wastewater flow from the pipe. These access points will allow crews to install a bulkhead, blocking flow in the pipe upstream of the collapsed area, keeping the site as dry as possible so crews can safely remove an extensive rock dam currently blocking the pipe.

DC Water is releasing new findings regarding the environmental impacts following the January 19, collapse in a section of the Potomac Interceptor. Based on flow monitoring data collected before and after interim bypass pumping was activated, DC Water estimates approximately 243 million gallons of wastewater has overflowed from the collapse site.

Update on Extended Repairs, Safety Measures, and Water Quality Monitoring

Overnight CCTV inspection of the Potomac Interceptor revealed the blockage inside the collapsed sewer line is far more significant, showing a large rock dam stretching approximately 30 feet downstream of the original failure.
