Original article Thursday:
The Michigan Department of Environmental Quality on Thursday said a Boil Water Advisory should remain in effect until noon Friday while testing on the water continues. It began Tuesday.
The advisory affects communities south of McNichols to the Detroit River and east of Linwood to Connor Street, which covers most of Downtown and Midtown Detroit, Hamtramck and Highland Park.
Preliminary tests show no contamination in Detroit’s water supply from a low water pressure problem at the Great Lakes Water Authority Water Works Park distribution facility, authorities said. More tests are being conducted.
"The first round of test results taken by the Great Lakes Water Authority (GLWA) related to the February 28, 2017 boil water advisory have come back clear,” said GLWA in a statement. “While these results are a sign that there is nothing wrong with the water, the Michigan Department of Environmental Quality is requiring the boil water advisory remain in effect throughout the originally stated 48-hour time period. A second round of test results will be returned tomorrow and upon a second clear result, GLWA will recommend that the boil water advisory be lifted. GLWA will provide additional updates as soon as they are available."
A boil water advisory is triggered when water pressure at a plant decreases to below 20 pounds per square inch. The city said pressure never fell below 20 pounds per square inch, however, the state issued the advisory as a precaution for the entire area served by the Water Works Park facility
Authorities recommend bringing all water to a boil for one minute, then letting it cool before using. Boiling kills bacteria and other organisms in the water.
