Residents in Flint, Mich., are still living in a state of emergency, waiting for answers about the safety of their water.

After almost two years of bad drinking water, it can be hard for them to trust researchers and officials – except for a group of independent researchers from Virginia Tech who exposed the problem last summer.

"So we trust them. We don't trust nobody else," says Bishop Bernadel Jefferson, a resident of Flint.

The researchers, led by Virginia Tech professor Marc Edwards, returned to the city last week to retest the water — performing the only test that compares results from last summer to today.

The city switched back to treated water from Lake Huron last October. To determine if the situation has improved, they needed testing. Everyone — including state and federal regulators — is waiting for what the Virginia Tech team finds.

Pamela Mayes says her water had lower lead levels, but she still doesn't trust it. She and her husband cook and wash dishes using bottled water. They had bought a house in Flint and planned to stay and retire in it.

"But now we don't know what we're going to do, you know?" she says. "I can't live like this for a very long time."

The team is made up of Flint residents and Virginia Tech students on spring break. They're making phone calls urging people to pick up and drop off their water testing kits. They then box up those kits for testing.

Many people in the city are tired of all this talk about the water — they just want it fixed.

Anurag Mantha, a graduate student with the Virginia Tech team, says there are a few people who say they are done with all this testing.

"People have lost hope in the city, so when we call them, they're like, 'I don't want to do anything with this water business anymore.' Some people are very welcoming, they're like, 'Oh, Virginia Tech, definitely, we'll test our water for you. So we are getting mixed responses," Mantha says.

They tested 269 homes last summer and their goal is to get at least 100 of these retested.

The broader goal, though, is to get things back to normal in Flint.

But health experts say there's no safe level of lead.

The current federal action level in drinking water is 15 parts per billion. Virginia Tech's random sampling last year found that Flint was 10 parts per billion over that action level.

Edwards says he does expect these new tests to show lead levels are dropping in the city.

"We want Flint to at least meet the same lousy standard that every other city in United States is," he says. "So in order to meet that, there is really three, I think, results that people are waiting for."

He's watching his own test and two from the state.
