A boil water advisory that officials initially said would be in effect until Thursday has been lifted.
That’s according to a press release sent this morning by the Great Lakes Water Authority and the Detroit Water and Sewerage Department.
DWSD received confirmation from GLWA indicating that the most recent round of testing shows no bacterial contamination in Detroit’s water supply. Two rounds of multiple samples were tested by GLWA indicating the water meets the Safe Drinking Water Act.
The Michigan Department of Environmental Quality (MDEQ) standard for issuing a boil water advisory occurs when water pressure decreases to below 20 pounds per square inch (PSI). During the water main break, Detroit’s pressure fell to 16 PSI in the defined area, therefore the advisory was issued as a precaution. There were other parts of the city experiencing low water pressure over the weekend, but not due to the significant drop in pressure necessary to expand the advisory area.
While the boil water advisory has been lifted, DWSD recommends that if water has not been used for six hours or more, water should run from the tap until it is cold and continue to run for an additional two minutes for fresh water
GLWA PRESS RELEASE
The advisory was due to a 42 inch main breaking at McDougall and Larned streets in Detroit late Sunday. The outage affected residents in the surrounding neighborhoods, more than 90,000 downtown office workers and guests for the North American International Auto Show.
