On Feb 28, Detroit Water and Sewerage Department issued boil water advisory that affected Detroit, Hamtramck and Highland Park. But now since yesterday, March 3 that boil water advisory Detroit has been lifted, according to the city of Detroit as quoted from Detroit free press.

The test results came back clear, finding “nothing wrong with the water,” according to a statement from the Great Lakes Water Authority. Since Monday, people in affected areas as above Detroit map had to boil their water before drinking it or using it to cook, in case it was contaminated with bacteria. But now no need to do that.

“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,” according to a news release from DWSD.

The department reported that the possibility of bacterial contamination occurred when an equipment malfunction caused a temporary drop in pressure from one pump at the system’s big water-treatment plant on East Jefferson, at the former Water Works Park (long closed to the public). The facility is operated by the Great Lakes Water Authority. “Bacteria are generally not harmful and are common throughout the environment,” a previous news release said.

In latest news release, the department said that the Michigan Department of Environmental Quality standard for issuing a boil-water advisory occurs when water presser falls below 20 pounds per square inch. Detroit’s pressure never fell that far, but the advisory was issued as a precaution, according to the release.
