FOR IMMEDIATE RELEASE
Springfield Plastics, Inc. Announces Preliminary Findings from Saturated Buffer System Water Quality Results
SPRINGFIELD, Illinois (February 25, 2015) – Springfield Plastics, Inc., in conjunction with the Agricultural Drainage Management Coalition (ADMC), has released preliminary water quality results for 2014 from their saturated buffer systems, which remove nitrate from water flowing in underground field drainage tiles before it reaches streams, rivers and other waterways. Springfield Plastics has been working with the Agricultural Drainage Management Coalition on a project spanning 15 sites across Illinois, Iowa, Indiana and Minnesota to study how saturated buffers work under different conditions and other conservation practices. Saturated buffer systems have a control structure that diverts the flow from the tile outlet to a lateral distribution line in a buffer strip. The lateral distribution line runs parallel to the buffer, and as the water is diverted to this line, saturation occurs. As this saturation, or lateral water movement through the buffer occurs, the vegetation, soil organisms and denitrification naturally removes nutrients like nitrate that are in the water, thus reducing the nitrates discharged to the streams. The preliminary 2014 findings show the nitrate concentrations in the streamside inspections are lower than the levels in the field tile prior to being diverted to the buffer. These findings were consistent across all 15 sites. Dr. Dan B. Jaynes, a Soil Scientist with the US Department of Agriculture commented, “I am pleased to see that these initial results show that saturated buffers have the potential to remove nitrate from tile drainage across the Midwest. Continued research and demonstration of this easy to install practice will help identify the best soils and landscapes for this practice.” Research will continue and further findings will be reported.
