Welcome to Public Health On Call, a podcast from the Johns Hopkins Bloomberg School of Public Health.

I'm Joshua Sharfstein, Vice Dean for Public Health Practice and Community Engagement,

and a former health commissioner here in Baltimore.

Our goal is to bring evidence and experience

to illuminate critical public health issues. If you have questions or ideas for us, please

send an email to public health question at jhhhu.edu. That's public health question at jhut.edu for future

podcast episodes. Hey listeners, it's Lindsay Smith-Rog Rogers, producer of public health on call, and we want to hear from you.

In more than 500 episodes since March 2020, we've been bringing you the latest on urgent public health topics like COVID-19, climate change, gun violence, monkeypox, racism, and more. We'll continue to cover these,

but we'd like to know what other public health topics would you like to hear more about.

Plus, you can enter to win some amazing podcast swag, including the Beach Toat,

featured on our Twitter account. Please go to publichealth.j.j.u.edu slash public health on call slash survey to take a

brief survey of potential future topics.

This will be open until September 9th, and that link is publichealth.j.j.org.com slash

public health on call slash survey. We're excited to hear from you and thank you so much for

listening. Today, a bonus episode on the water crisis in Jackson, Mississippi, where flooding

has caused profound damage to the city's water treatment system, leaving many thousands of city

residents without water. Dr. Richard

Mazzle, an environmental historian at the University of Houston, talks to Dr. Josh

Sharfstein today about the origins of the crisis. They discuss decades of disinvestment,

environmental racism, and the very real danger the crisis is now posing to dialysis patients.

Let's listen.

Professor Richard Mazzle, thank you so much for joining me in public health on call
