Laurel, Md. – April 1, 2024 – WSSC Water today released its annual water quality report, which provides important information about the source of drinking water, how it is filtered and purified, and detailed laboratory results. The report also highlights the men and women of WSSC Water who work 24/7/365 to ensure exceptional water quality – from source to tap. Thanks to their relentless commitment to safety, service and reliability, Maryland’s largest water utility has achieved 106 years without a single drinking water quality violation.

Powell. “Despite our exceptional track record of water quality excellence, we are not resting on our laurels. As an anchor institution, we recognize that our work is a building block that uplifts communities, and we remain laser focused on protecting public and environmental health.”

WSSC Water’s Silver Spring laboratory performs more than 500,000 water quality tests each year. The report details important water quality topics, including:

  • Where your water comes from
  • Impacts on water quality
  • How and why we test your drinking water
  • An explanation of the filtration process
