Annual Water Quality Report
Each year, the U.S. Environmental Protection Agency requires water systems to issue Consumer Confidence Reports (CCR), also known as the Water Quality Report, by July 1 detailing water quality for the previous year. This annual report informs water customers where the City’s drinking water comes from, how the water is treated, what chemicals it contains, and how it meets federal standards for tap water.
The Baltimore City Department of Public Works (DPW) uses electronic delivery to disseminate its Annual Water Quality Report to City and County water customers. The 2019 water quality data (Jan. 1, 2019 to Dec. 31, 2019) is available online: publicworks.baltimorecity.gov/waterreport. Customers who want a printed copy of the report can call 311 or (410) 396-5352 (Baltimore County customers).
