Science and Politics of Mining (start time: 6:49)  On August 5 an inactive mine named Gold King, which had been leaking toxins for years, spewed more than 3 million gallons of toxic sludge into a creek that feeds into the Animus River in southwest Colorado. Its neon orange path of wastewater was shocking. But also shocking is the long history of acid mine drainage pollution and the lax regulations that allow mining companies to basically walk away from their disasters. Dr. Mark Williams, a professor of geography at CU Boulder, and an expert in mountain hydrology and hydrochemistry., has worked on remediation of several mines in the state. He speaks with How On Earth host Susan Moran about the anatomy of mines, how this disaster happened, what it suggests about the many other precarious mines in the state, and what should be done to prevent such disasters from happening.

Public health risks of BPA

Dr. David Dausey, Director of the Mercyhurst Institute for Public Health
(start time: 5:50). We Coloradoans pride ourselves on our healthy habits — eating right, exercising, and paying attention to what’s in the food we eat. Yet many of the things we use everyday, like water bottles, sunscreens, makeup, and – OK, soda cans — are full of toxic chemicals. Many of them are untested, and may be insidiously making us sick. One of the more controversial compounds is BPA, which is used to make some hard plastic bottles and other food packaging. Today we have with us public health expert Dr. David Dausey to talk about BPA –bisphenol A — and other environmental toxins. He directs the Mercyhurst Institute for Public Health in Pennsylvania.
