blue cldy soils. It boggles by mind, tor an attainable goal In one 



area is scientifically Impossible in another. 



The soils 1 am familiar with have a tremendous buffering 

 capacity and a chnnge In management may not be reflected in 

 measurable results for m^ny years. When a water quality problem Is 

 coining from an Industrial discharge, point source, the company must 

 be convinced they are the problem. Then they must Invest In 

 technology and equipment to correct the problem. As soon as 

 everything Is installed and working, the results can be measured. The 

 same time Is required for recognition and Implementation of 

 technology In production agriculture. However, with non point source 

 type pollution, like agriculture, measurable Improvement In water 

 quality may still be 10 to 20 years away. 



Almost by definition, the prairie pothole soils of Iowa are 

 synonymous with wetland legislation. I believe It is common 

 knowledge that wetlands are a cleansing agent. i have heard several 

 proposals on how to use this Information, but none seem practical 

 either for the environment or financially for agriculture. 



virtually all land owners in Iowa have Invested from thousands 

 to hundreds of thousands of dollars In tile, terraces, and waterways 

 all done to the specifications of the Soil Conservation Service, 

 where erosion is a problem the loss of soil is truly the greatest 

 clean water risk. As legislation and rules are written, the 

 protection of current practices and funding for further measures are 

 Imperative.
