Water Quality Reports
WSSC Water is proud to present our annual Water Quality Report, which shows that our record of more than 106 years with zero water quality violations is going strong.
WSSC Water's record of excellence has lasted for more than 106 years
WSSC Water is proud to present our annual Water Quality Report, to keep you informed about the safety and quality of the drinking water we provide. The report summarizes the results of more than 500,000 water quality tests we conducted in the previous year.
And as in years past, WSSC Water is reporting zero water quality violations - continuing our record of more than 106 years without a violation. That record is a testament to the hard work of everyone at WSSC Water and our commitment to providing you with clean, safe drinking water. It takes a lot of dedication and a lot of work to produce our Water Quality Report, which summarizes the results of more than 500,000 water quality tests we conduct every year.
Our Water Quality Report, which is also known as our Consumer Confidence Report, is published every year by April 1, well in advance of the U.S. Environmental Protection Agency's July 1 deadline. To view a copy, click on one of the buttons below. Customers who need a paper copy can email us at communications@wsscwater.com. (Reports from previous years are listed farther below.)
