WSSC Meets or Surpasses Water Quality Standards for 97th Year in a Row

2015 Water Quality Report Now Available Online

| News Release



Laurel – March 31, 2016 – The state of WSSC’s water quality is strong, according to a report released today, keeping alive a 97-year streak of meeting or surpassing federal drinking water safety and quality standards.

“The tragedy in Flint, MI, sparked a national conversation about the safety of our drinking water. Many have been asking, ‘Could this happen to our water supply?,’” said Carla A. Reid, General Manager and CEO. “We understand this concern, and I want to assure all of our customers that the safety of our drinking supply is of the utmost importance to me and the 1,500 dedicated employees at WSSC. I am pleased to report to you – and our water quality experts confirm – WSSC’s drinking water supply is indeed safe.” WSSC has never had a drinking water violation in our 97-year history.

Source water taken from the Potomac and Patuxent rivers is first treated by our water filtration plants where it is tested hundreds of thousands of times each year, including tests for lead, before being sent out  to homes and businesses through our 5,600 miles of distribution pipes. The results allow WSSC to make any adjustments to our operation or treatment process to maintain the highest level of water quality.

The report, which is released once a year, provides the more than 1.8 million WSSC customers assurance that they will receive the highest quality of water each time they open their tap.
