Tristate Study

Timeframe: 1996 - 1999
Location: Kansas, Iowa, Nebraska
Point-of-Contact: Debbie Baker

In the mid-ninties, KBS embarked on a large nonpoint source pollution study commonly refered to as the Tristate study. From 1992 - 1994 sixteen watersheds in the Western Corn Belt Plains of Kansas, Nebraska, and Iowa were sampled at five sites each.
