The city of Tulsa’s Melissa Gray joins us for this week’s edition of the Listen Frontier podcast. Gray is the environmental compliance supervisor for the Water and Sewer Department. Part of her job is to make sure the public understands that the city’s water supply is safe and clean, and what measures the city takes to ensure that it stays that way.

The focus of today’s podcast is lead and copper levels in the city’s water supply. As Gray explains, these are  not problems in Tulsa. But well-publicized problems in Flint, Michigan, and a recent report in Rueters have kept the issue alive in the public consciousness.

Here’s what Gray had to say about those reports. For more information on the city’s water supply, or to contact the city’s Water and Sewer Department, go to
