Researchers, Economists & Residents - Bottled Water Price Drivers

I'm working on a story for DW on why bottled water keeps getting more expensive, and why the answer has almost nothing to do with water. The raw material is free. What you're paying for is plastic, brand, and the failure of governments to deliver safe tap water. For 2.2 billion people with no alternative, every oil shock and energy spike hits directly. Looking to speak with researchers, economists, policy experts, or anyone living this reality. DM me or email at [email redacted]
