Four-State Study Tests Nitrate-Reduction Technology

Approxmately 265 square miles drain into the Lake Springfield watershed from an area covering portions of three counties.  
Researchers are tracking technology at two test sites in Auburn intended to keep the nitrate byproducts from 300 farms within the watershed out of streams, rivers and ultimately the lake.  The sites -- known as "saturated buffer zones" -- are among 15 in Illinois, Iowa, Indiana and Minnesota in a larger study on reducing nitrates that threaten water quality and aquatic life.
