Alan Overton is the pastor at Fellowship Missionary Baptist Church in Flint, Michigan.

Congratulations.

He carries himself with gravitas, wearing a suit, tie, and cufflinks.

And he tells me there's one thing that could always strip away that air of buttoned up poise, drinking from a water fountain.

I'm a big kid in that aspect. I like water fun. I like to see the water screw it up and try to get into my mouth. But I'm not a fan of it anymore.

In 2014, the government pumped water into Flint homes that corroded the lead from service pipes.

And for months, officials insisted the water was safe. Internal emails have shown that they continued to tell people it was drinkable, even when state leaders knew it was poisoned.

Pastor Overton was one of the people who sued Flint and Michigan state officials. That resulted in a settlement for almost $100 million to get lead pipes replaced.

At the church, he's had all the water fountains turned off, most have been removed from the building.

There's still one in the church basement covered in a big trash bag.

Pastor Overton pushes the button and nothing comes out.

Right next to it is a water cooler that everybody uses instead.

Pastor Overton's mistrust of tap water goes beyond fountains, even beyond his hometown of Flint. He was recently in Ohio.

We were out of vacation and I had my grandson with me and I was like, whoa, we're buying some water. We weren't even in Michigan.

So now buy some water. Let me just buy you a bottle of water. I don't trust water fountains anymore.

Anywhere.

You hear this sort of thing a lot from people in Flint. They've been on a long hard road for years.

Today, more than 90% of the lead pipes running to people's homes in Flint have been replaced. The water gets tested for lead and it's clean.

But Pastor Overton says that trauma has not gone away.

The worst part of it all is that you trusted people that you thought you could trust.

In the government, you mean?

In the government. If you can't trust the government to tell you the truth about water, then we got some serious problems in America.
