Comparative Risk Assessment And Alternative Closure Techniques Of Abandoned Manure Storage Basins In Central Minnesota, Joe Storlien

Culminating Projects in Environmental and Technological Studies

Manure storage basins are a necessary component to many animal agriculture production systems. Manures within these basins are a valuable source of nutrients for crops, however they must be managed appropriately to protect water resources. Some contaminants found within animal manures may pose potential human or environmental health risks.

The objectives of this study were to: 1) determine characteristics of eight sites containing abandoned manure storage basins; 2) quantify contaminant concentration in soil and groundwater at the abandoned basin sites; 3) quantify the comparative risk posed by the abandoned basins; 4) determine overall comparative risk posed by the abandoned manure …
