For months, reporters Susanne Rust and Matt Drange of The Center for Investigative Reporting have asked questions to find out what happens to the waste that’s pulled from beneath Silicon Valley’s Superfund sites. Now, it’s your turn.

Our new investigation, in partnership with the Guardian US, is a complex story with big implications for the U.S. Environmental Protection Agency’s Superfund cleanup program and its hidden environmental toll.

To help break down what we found, Rust and Drange will be available at 3 p.m. ET/noon PT today to answer your questions about their reporting and what it could mean for you.

If you live near a Superfund site (find out by using this interactive map) and want to know what to look out for, or about the costs to us all, toss your questions in the widget below and come back at 3 p.m. ET for the live discussion.
