Quantity and Quality of Seepage from Two Earthen Basins Used to Store Livestock211 Waste in Southern Minnesota During the First Year of Operation, 1997-98

摘要

The U.S. Geological Survey, in cooperation with the MPCA (Minnesota Pollution211u001eControl Agency), studied the quantity and quality of seepage from two earthen 211u001ebasins used to store livestock waste in southern Minnesota during the first year 211u001eof operation. One basin (site A), located at a small dairy farm, holds a manure-211u001esilage mixture, milkhouse wastewater, and local runoff; the other basin (site B), 211u001elocated at a large hog farm, holds a manure-water mixture from a nearby gestation 211u001ebarn. Monitoring systems were installed below compacted clay liners in portions 211u001eof the sidewalls and bottoms of the basins to determine the quantity and quality 211u001eof the seepage.
