The Iowa House passed a bill to see if hog manure stinks. The study will cost taxpayers $23 million over 5 years.

You don't need to spend $23 million to tell you that hog manure smells bad. Just drive around rural Iowa with your windows down and you will be be able to tell that hog manure reeks.

To make it worse, taxpayer money was spent in 2002 for a similar study.

Previous studies, including one in 2002 by Iowa State University and the University of Iowa, have linked respiratory illnesses with large animal confinements. The 2002 study, requested by former Gov. Tom Vilsack, was overseen by the Iowa Department of Natural Resources. The study recommended that manure be largely covered by soil immediately upon field application.

The bill now goes to the Iowa Senate. If you already know that hog manure smells bad and don't like to see taxpayer money wasted, call your Senator and tell them the Odor Study stinks.
