We're so excited to present these results of a valuation of state policies to reduce PFAS levels in drinking water.

And we found a 55% reduction in average concentrations after the policy was implemented.

So it's interesting you ask that.

Our government colleagues were not surprised.

They said, you know, Hari, we know when we put these policies in place, we expect to see a drop.

That's why we do them.

But I think we were excited to see this because in public health,

Often our message is, you know, this thing is bad for you.

This disease is becoming more prevalent.

But here we were actually able to demonstrate a positive impact of a regulation.

So we definitely have observed levels that are below the maximum contaminant levels that are called these regulatory limits.

But I think that there's another part of this story, which is the ongoing evolution of our understanding of the health impacts of long-term exposure.

And so something that a lot of folks will ask is, you know, that's great that the water levels have dropped today.

But have I been drinking water for the last 20 years that has had higher levels?

And if so, how does this help me?

And I think that that's a very fair question to ask.

And so I think when you ask the question about safe levels, I think we're still kind of understanding these long term health risks.

So that's a complicated question.

It's a good one.

But what I will say is, based on a lot of this accumulating evidence from animal studies and from toxicology studies and cells, what has been shown is that
