Criteria For Evaluation

Technical evaluation of swine waste management systems considered ''environmentally superior'' includes consideration of the following performance parameters: 1) prevention of waste discharge to surface or ground water; 2) elimination of emissions of ammonia and odors to the atmosphere; 3) elimination of discharge of pathogens and disease vectors; 4) elimination of discharge of nutrients and minerals, especially heavy metals, to soil; 5) operational and economic feasibility; and 6) acceptability for permitting by local authorities. A detailed discussion of a program that addresses all of these parameters under full-scale performance testing conditions is found in Ref. 5.
