  • Failed some Legal Limits
  • Met all Reporting and Monitoring Requirements
  • Uses Chlorine disinfectant

The City of Baltimore draws water from the Liberty Reservoir and Loch Raven Reservoir watersheds, located in Baltimore County and uses water from several potable water storage tanks and pumping stations. In 2009, Baltimore came in 69th in a drinking-water comparison done by the Environmental Protection Working Group (EWG) of the 100 biggest US cities’ tap water quality. Due to the old pipes and plumbing the water flows through once it leaves the treatment facility, the city must use higher amounts of chlorine to disinfect the water. In recent years, radioactive elements, lead and potentially carcinogenic disinfectant byproducts have exceeded health guidelines.
