Controversy continues over a sand and gravel mining operation in Ann Arbor Township. What is referred to as the "Vella Pit" had been accused of making some water wells run dry and polluting local waterways. It's been back up and running for a while now. Operators say it's safe, but some residents report increased sediment in their well water and want the operation halted. WEMU's David Fair talked with Ann Arbor Township resident and activist Amy Olszewski about the current situation and where it’s headed.
