Bloomington public works employee Jim Crowley jokes he has a crappy job. He monitors what you flush down the toilet. In part 4 of the GLT News series Hows the Water?, follow the waste from your toilet, and see where it ends up. Also hear from Ecology Action Center Director Michael Brown on the dos and don't of flushing, and a Willis Kern Interview with the head of NPR looking at the future of radio. Michael Brown of the Ecology Action Center is in studio to talk about waste water, rain water, gray water, and other kinds of water. The radio news business is at a crossroads, in part because of emerging technologies but also because of the economic realities of the 21st century. As a subset, PUBLIC radio faces an uncertain future. The president and CEO of NPR, Jarl Mohn stopped by the GLT studios to talk with Willis Kern.
