BALTIMORE — The Boil Water Advisory was lifted in certain areas of Baltimore where E. coli was found in the water. This is after samples were retested from those area and came back negative.

The Precautionary Boil Water Advisory has been lifted for a portion of Baltimore City and the area of concern in Baltimore County.

Baltimore Mayor Brandon Scott and Department of Public Works Director Jason Mitchell provided an update Wednesday evening about the advisory that had been issued after E. coli and total coliform were detected in the water in West Baltimore.

They said several rounds of water quality tests were performed by DPW in the areas covered by the Precautionary Boil Water Advisory and all results confirmed that the water is safe to consume.

Mayor Scott has also announced a 25 percent discount will be given on the next cycle of water bills to every Baltimore City resident.

Mayor Scott said that still impacts about 1,000 residents.

Scott and Mitchell said the reason there is partial lifting and not a full lifting is that DPW is awaiting analytical data from the laboratory to confirm that there is no E. coli and Total Coliform in the samples taken within the Required Boil Water Advisory and remaining Precautionary area.
