## Resource

A report from the Environmental Working Group claims thousands of feeding operations are off the DNR's radar. A representative with the Iowa Pork Producers Association says the DNR is following state law. Host Ben Kieffer speaks with the co-author of this report, Anne Schechinger, about how mapping animal operations relates to water quality issues, and Pork Association legal counsel Eldon McAfee shares what he thinks the report gets wrong. Then, Kieffer speaks with the recipient of the "Nobel Prize for statistics," University of Iowa professor emeritus Luke Tierney.
