Detroit boil-water advisory lifted.
The second round of test results came back clear, finding "nothing wrong with the water," according to a statement from the Great Lakes Water Authority.
People in affected areas this week had to boil their water before drinking it or using it to cook, in case it was contaminated with bacteria.
"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 Detroit Water and Sewerage Department.
Related: 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 today’s 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.
