Water from the East Lansing-Meridian Water Sewer Authority tested clear on Saturday, paving the way to a lifting of the boil order as soon as Sunday.
The authority issued the order for East Lansing, Meridian Township, and parts of MSU on Friday after a problem with a filter caused the water to become cloudy and possibly prone to other problems.
The order affects more than 70,000 customers.
The Michigan Department of Environment Quality wants the water to undergo a second round of testing before getting the all clear. Tests take about 24 hours to complete.
If Saturday’s sample tests clear on Sunday, officials expect to be able to lift the boil order by 3 p.m. on Sunday.
The order is causing headaches for residents and businesses.
