Listen to part two of the Michigan Radio documentary, Not Safe To Drink.

If you missed part one of Not Safe to Drink, you can hear it here.

The tap water in Lee Anne Walters’ home in Flint was causing her family’s health problems. Tests show her water had extremely high lead levels. Her son Gavin was diagnosed with lead poisoning.

“How does this happen in the United States?” she asks. “I mean, you hear about it in third world countries, but how does this happen, specifically in a state that is surrounded by the Great Lakes?”

It’s a good question. How did this happen?

To understand, we have to go back to 2013.

Flint was broke -- like “nearing bankruptcy” broke.

Flint had a string of these state-appointed financial hatchetmen during this time -- trying to get the city’s finances straight.

They were looking for savings everywhere, and they had their eyes on the expensive water they buy from Detroit, so when Genesee County decided to build a new water system, one that’s separate from Detroit, Flint was definitely interested in joining.

Once it was clear Flint could save millions of dollars a year with the new system, Flint got on board.

But there was a catch. The new water system wasn’t built yet, and it wouldn’t be ready until the summer of 2016, at the earliest.

And once Detroit realized Flint was going to leave its system, it jacked Flint’s water rates up even more – to the tune of $10 million over the two years the new pipeline would be under construction.

So in the spring of 2013, Detroit kind of had Flint over a barrel.

It was state treasury officials who got creative.

Their solution?

Forget Detroit, Flint’s emergency manager said. Let Flint get really cheap water from the Flint River.

That brings us to April 25, 2014.

It was a Friday morning. A small group of city and state officials got together inside the Flint water plant. It was a big day. The day Flint stopped buying Detroit’s water.

There was a countdown, and then Flint Mayor Dayne Walling pushed a tiny black button.

That push of a button closed a valve in an underground pipe that brought water from Detroit. Flint was officially cut off from Detroit’s water.

To celebrate, the group took small clear plastic cups, and filled them with the city’s new drinking water. In TV station WNEM’s report from that day, you can see the group come together in a small circle. They raise their plastic cups, smile, and make a toast.

But the celebrations didn’t last long.

City residents started complaining right away.

The water was brown or reddish.

It stank.

It tasted weird.

Darnell Earley was Flint’s emergency manager at the time of the switch.

“What we have to do is respond to that, find a way to fix it, make it better and move on,” said Earley.

Things did not get better.

Four months after the switch, the city detected E. coli in the water. E. coli is a nasty bacterium. It can make you very sick, and it can even cause kidney failure in kids and the elderly.

Residents were told to boil their water. These boil water advisories came out right around the time kids were heading back to school.

Phylis Brock is a lunch lady at Flint Community Schools. She says there was one little girl who would come into the cafeteria in the mornings, and she was really concerned about the water Brock was using to make her oatmeal.

The little girl’s mom told her to be careful.

“’So I had to go back and forth with her for about three days. ‘It’s bottled water’ – ‘Yes, I boil it’ – ‘Mom said no’ – and so finally I’ve convinced her. She’ll eat oatmeal again,” said Brock.

Brock’s boss, the executive chef at Flint Community Schools, Wally Janeczek, said there were other problems.

“Some of our cooks started mentioning about how the water was smelling and that when they turned it on, it didn’t look quite right,” he said.

Janeczek didn’t take any chances. Five months after the switch, he started buying gallons of bottled water in bulk to prepare and wash all of the school food.

Janeczek’s main concern was the E. coli. You can’t make food for a school full of kids laced with bacteria that can make you violently ill. And Flint did get a handle on the E. coli problem, but killing the bacteria brought a whole new set of problems.

The city started dumping chlorine into the water system. Now people complained the water smelled like a swimming pool.

Flint resident Amber Hasan says the smell wasn’t the scary part.

"My eyes are burning in the shower and I was like, 'oh my goodness, like, what's going on?'"

“My eyes are burning in the shower and I was like, ‘oh my goodness, like, what’s going on?’ I get out the shower and I can’t see for a minute because my eyes are burning from whatever,” said Hasan.

Meanwhile, six miles south of Hasan’s house, Lee Anne Walters started noticing alarming clumps of hair in her shower drain.

“I had lost a bunch of hair,” says Walters. “At one point I had lost all my eyelashes. I still wear fake eyelashes because my eyelashes did not grow back what they were before. It makes me very self-conscious, so that’s now why I wear fakes.”

Flint’s water damaging to car parts

If you’re thinking these people are delicate flowers with sensitive skin and eyes, consider this: Flint’s water was so caustic; it was damaging car parts at one of General Motors’ engine plants. Tom Wickham is a spokesman for GM’s Flint operations.

“So what happened was we had employees who were checking the parts and they noticed there’s something wrong here. There was some corrosion, some rust forming and they decided to raise the red flag,” says Wickham.

GM tried to treat the water to get rid of the extra chlorine that Wickham says was rusting the engine parts. It didn’t work well, so they brought in semi-trucks full of water instead.

It wasn’t cheap.

“I don’t have that number and that’s not something we’d disclose,” he says. “When I look at, what I was told at the time was, ‘it’s just a lot of money.’”

But GM was kind of lucky. A sliver of the company’s sprawling property is technically in Flint Township, not the city of Flint, and Flint Township still gets its water from Detroit. GM discovered it could hook up through the township and get its water from Detroit again.

So eight months after the switch, GM left Flint’s water system. The company was one of Flint’s largest water customers. GM pulling out meant the city lost almost half a million dollars a year.

And then, a month later – nine months after the switch – people living in Flint got a notice in the mail. The notice said Flint was in violation of the Federal Safe Drinking Water Act.

It turns out: the city dumped too much chlorine in the water, so much that a by-product of the disinfectant, called trihalomethane, was above levels set by the federal government. Over time, exposure to trihalomethane can increase the risk of cancer and other health problems.

Getting nowhere with city and state officials

It’s no surprise that angry people showed up again in droves at city hall, but their concerns were pretty much blown off.

“The city water is safe to drink,” said then-mayor Dayne Walling. “My family and I drink it and use it every day.”

Walling is a former mayor now, thanks to the water crisis.

By this time, people were bypassing city hall – which wasn’t offering much help, or even acknowledging the problem.

In January 2015, in single-digit cold, people like Mike Sargent took matters into their own hands. They started giving out cases of free bottled water. Sargent spent the morning loading them into people’s cars and trucks.

“You know, I knew that our intention would only be a band-aid on all that needed help,” says Sargent.

By this time, Flint had a new emergency manager. Jerry Ambrose insisted the water was safe. In fact, Ambrose seemed more concerned about bad press than bad water.

“It doesn’t have to travel very far out of Flint to see that this news has been picked up not just in the Flint area, but throughout the state, and even beyond that,” said Ambrose. “There’s clearly a perception issue.”

But Flint residents didn’t think it was a “perception issue.”

At city hall, residents like Claire McClinton demanded the city reverse course.

“I mean, what do we have to do to get them to turn the water back on to Detroit?” asked McClinton. “We survived bacteria. We’ve had boil water advisories as a result. They put too much chloride in the water, we’ve got trihalomethanes, and it’s just been one disaster after another.”

But Ambrose was blunt: The city was broke. It couldn’t afford to reconnect to Detroit, even if it wanted to.

A leaked report from the EPA

Through that spring of 2015 and into the summer, folks hauled their milk jugs full of discolored water to meetings.

They brought their hand-lettered signs down to city hall.

Good Samaritans handed out bottled water.

But the “Flint water crisis” hadn’t been coined as a phrase yet. Out-of-town reporters weren’t flocking to cover the rallies or tell the story, but then, in late June, something shifted.

In her little yellow house on the south side of Flint, Lee Anne Walters opened her laptop, and there, in her email, was a draft report from an EPA guy who had come to her house to check out her tap water.

"You know, talking about the 'hazardous waste levels' of lead was certainly attention grabbing."

She immediately forwarded the email to a reporter she had met in the spring. Curt Guyette is an investigative reporter who works for the ACLU of Michigan.

“You know, talking about the ‘hazardous waste levels’ of lead was certainly attention grabbing,” says Guyette.

The draft EPA report showed lead levels at Lee Anne Walters’ house were way worse than she thought.

We’re talking simply jaw-dropping numbers.

Let me put it this way: If you have a glass of water, and it has a lead level of 5,000 parts per billion, the EPA considers it hazardous waste. One sample from the Walters’ house had more than 13,000 parts per billion. And that’s not even the scary part. The scary part is this report said there was reason to believe that the Walters’ home could be a canary in the coal mine.

“It’s not this individual home. It’s not coming from inside the home. It’s coming from outside the home," Guyette said. We know now, from emails and other records, that, for months, the EPA had been warning state officials that something was wrong with Flint’s water.

But you won’t hear from the guy who works for the EPA who wrote this report; the guy who was doing most of the warning. The EPA won’t make him available, but Guyette managed to get him on the phone before writing a blog post about the report.

“He wanted the information to get out,” says Guyette. “And he was willing to go outside normal EPA protocol in order to make sure that happened.”

This leaked report, this was the very first time any official had publicly said Flint’s water may not be safe.

But back then, the EPA report wasn’t finalized, so Guyette was lucky to have scored this one conversation with the author.

The EPA wasn’t talking to any reporters about it.

The state’s non-response response

So back in July, I turned to Brad Wurfel, the spokesman for Michigan’s Department of Environmental Quality. Wurfel agreed to talk to me about the EPA report. The first thing I asked him was: what responsibility does the state have in making sure lead isn’t getting into people’s drinking water?

"Let me start here. Anyone who is concerned about lead in the drinking water in Flint can relax."

“Let me start here,” Wurfel said. “Anyone who is concerned about lead in the drinking water in Flint can relax. There is no broad problem right now that we’ve seen with lead in the drinking water in Flint.”

It turns out, there was a broad problem, and it turns out, the MDEQ is exactly the agency responsible.

And we know now that the same week I talked to Brad Wurfel, was the same week some of the people he works with at the MDEQ realized that Flint’s latest lead tests weren’t looking too good.

The tests were bad enough that at that point, they should have informed the public about the broad lead risk, but that’s not what happened. Instead, state and city officials kept telling residents there was no lead problem in Flint’s water; that this EPA report was wrong; that the report was written by a “rogue employee.”

About a month after the EPA’s report was plastered all over the media, Lee Anne Walters went with a group of Flint residents and concerned pastors to Lansing. They were able to arrange a meeting with top officials at Michigan’s Department of Environmental Quality.

Walters had hoped that, after she leaked the federal report, state officials would take their concerns more seriously.

“They blew us off like we didn't know what we were talking about,” says Walters.

State officials told Walters and others that the EPA employee who gave her the report had been “handled,” but Walters had met someone who did take her seriously.

Help for people in Flint, Michigan comes from a professor in Blacksburg, Virginia

Later that afternoon, after that unproductive meeting with state regulators, she made a phone call that helped change the course of Flint’s water crisis.

Marc Edwards is an environmental engineer, and a professor at Virginia Tech. He’s studied the corrosion of old water systems for decades. Edwards has tested probably 30,000 homes for lead in his career. He’s never seen anyone with higher lead levels than Lee Anne Walters’ home in Flint.

On that warm, Tuesday afternoon in August, when Walters called Edwards to tell him how awful that meeting with the state went, Edwards remembers hanging up the phone and physically shaking with anger.

“I mean this is an imminent and substantial endangerment to children, and for me sitting 15 hours away, I can't believe how people could just sit there and let other children drink that water,” says Edwards.

“I mean, how could you do that?”

Edwards couldn’t sleep. He decided he had to drop everything.

He got four grad students together, and a bunch of lead test kits. Two days later, they loaded up in Edwards’ 13-year-old white “soccer mom” mini-van and drove 15 hours straight – directly to Flint.

By mid-August, the small research lab on the 4th floor of Durham Hall at Virginia Tech was a beehive of activity. Cardboard FedEx boxes full of lead testing kits from Flint started arriving for analysis.

Lee Anne Walters, and a group of Flint residents helped hand out the testing kits all over Flint. In all, graduate students, like Anurag Mantha processed more than 800 samples.

“We spent so many weekends here trying to get that done on time, so that we could get the data and start giving out the results to people because every hour, every day, we're delayed that thing, more and more people were still drinking the Flint water,” she says.

The tests showed lead levels in Flint were pretty bad.

Alerting the people of Flint

Bad enough, that one afternoon in mid-September, he went back to Flint. On the lawn in front of Flint City Hall, Edwards addressed several reporters, and about two dozen Flint residents.

Point by point, he explained why there’s a dangerous lead problem in Flint.

“This problem has arisen because of what’s known as a corrosion issue. So most cities, like Detroit, have treatments for their water where they put chemicals in the water to stop corrosion,” he said to the crowd. “You can’t see it, but there’s an iron nail in this bottle here.”

He held up two small bottles of water. In one with pretty clear water, you can see a small nail in the top. The water in the other bottle is orange. This was Flint’s water. It was basically eating the nail. The iron nail was disintegrating into the water.

Edwards says Flint’s corrosive water is doing the same thing to distribution pipes all over the city.

“Flint is the only city in America that I’m aware who does not have a corrosion control plan in place to stop this kind of problem,” Edwards said. “So this water looks bad. It smells bad. It tastes bad. And this is part of what people have been complaining about.”

But, Edwards warned the crowd, the real danger isn’t the iron you can see in the tap water. The real danger is odorless, tasteless lead, that’s also leaching from the distribution system.

Edwards said people in Flint should protect themselves against the lead exposure immediately.

He told them to stop drinking the tap water; to buy a certified lead filter, or bottled water if they can afford it.
