Two of three Baltimore sites that originally had E. coli contamination in water have since tested negative, officials say

Two days after the city first announced that E. coli had been found in tap water samples taken in West Baltimore, two of the three sites where the bacteria were first found now show negative results, officials said Wednesday. The city Department of Public Works first discovered the bacteria in water samples taken from Sandtown-Winchester and Harlem Park over Labor Day weekend. On Monday, Public Works told residents across a large swath of West Baltimore and southwestern Baltimore County to boil their water.
