Baltimore Drinking Water Overview
Population: ~585,000 | Source: Liberty, Loch Raven, and Prettyboy Reservoirs
Baltimore draws from three protected reservoirs north of the city. While the source water is generally good, Baltimore's aging distribution system is among the oldest in the country. Lead service lines, estimated at over 20,000, remain a significant concern. The city's combined sewer system can overflow during heavy rain, though this primarily affects waterways rather than drinking water.
