If your water starts tasting/smelling like chlorine – don’t worry it’s just the annual “spring cleaning”. From a press release:

Spring Cleaning the Water Distribution System

From March 18 through April 29, 2013, the disinfectant in drinking water will temporarily switch from chloramine to chlorine.

The annual switch in water disinfection is part of a routine program to clean and maintain water distribution systems in the District of Columbia, Arlington County and Falls Church. During the temporary switch to chlorine, local water authorities will also conduct system-wide flushing to enhance water quality. This program is standard practice for many U.S. water systems that use chloramine during the majority of the year.

The Washington Aqueduct is the organization responsible for treating – and disinfecting – drinking water for the District of Columbia, Arlington County, and Falls Church, Virginia. Local water authorities are responsible for monitoring drinking water to ensure chlorine levels continue to meet safe target levels.

Individuals and business owners who take special precautions to remove chloramine from tap water, such as dialysis centers, medical facilities and aquatic pet owners, should continue to take the same precautions during the temporary switch to chlorine. Most methods for removing chloramine from tap water are effective in removing chlorine. Individuals with special health concerns should consult a health care provider on the use of tap water.

During this time, individuals may notice a slight change in the taste and smell of their drinking water. Local water authorities recommend running the cold water tap for approximately two minutes and refrigerating cold tap water for a few hours to reduce taste and odor. Water filters are also effective in reducing chlorine taste and odor. For more information, please contact the appropriate water authority below.

  • what pool is that?

  • This is being done as part of the international Communist conspiracy to sap and impurify all of our precious bodily fluids.

  • Had a funny experience with this last year: My kids like those fizzing color tablets for the bath. During the chlorine switch, the colors didn’t work. I thought we had a bad batch. Ah, fun with chemistry.

  • This led me to buying my first britta so many years ago!

    But it reminds me to be grateful for safe drinking water. Our descendants never had the luxury of safe drinking water on tap and neither do most of the people in the world. We are lucky.
