Water Quality

Washington Suburban Sanitary Commission is pleased to present its annual Consumer Confidence Report. This report, also known as the Water Quality Report, is required by the U.S. Environmental Protection Agency (EPA) and summarizes the results of over 500,000 water quality tests conducted in the previous year.  WSSC Water takes great pride in providing an essential service to our customers in Montgomery and Prince George’s Counties.  This commitment to safe, clean water is why WSSC Water is once again able to report zero drinking water quality violations, a tradition that extends over 100 consecutive years.

While the EPA requires distribution of the report by July 1st, WSSC Water electronically publishes a calendar year’s Water Quality Report by April 1st of the following year.  If needed, customers can call the Commission at 301-206-8100 to request a paper copy of our annual Water Quality Report.
