The Tennessee Valley Authority Produced a Booklet Downplaying Coal Ash Risks. Top Researchers Call it ‘Dishonest.’  - Inside Climate News

> Vengosh leads a research group at Duke that has published [numerous peer-reviewed papers](https://sites.nicholas.duke.edu/avnervengosh/research/energy-water-nexus/coal-and-coal-ash/) on coal ash contamination in the environment. Coal ash, or coal combustion residuals (CCR), is the solid material left over after burning coal. It contains potentially toxic levels of substances like mercury, arsenic and lead that are associated with human health problems, including cancer.

> “I’m not sure why they’re having this campaign, but basically everything there is lies, to be the most direct I can,” Vengosh said of the booklet.
