Today, the Baltimore City Department of Public Works (DPW) is announcing that its 2023 Water Quality Report is available online. This annual report provides Baltimore City, Baltimore County, and Howard County residents with important information about where the City’s drinking water comes from, what chemicals it contains, and how it meets federal standards for tap water. In this report, DPW highlights our employees who monitor and treat the water from the City’s reservoirs, Loch Raven, Liberty, and Prettyboy, and take steps to safeguard the water throughout the distribution process.
