Since 2002, the Professional Nutrient Applicators Association of Wisconsin (PNAAW) and UW Extension have conducted 15 live action field events to train applicators, farmers, first responders and agency staff how to respond in the event of a manure spill or release. As these sessions have evolved and training materials developed, the question of how many spills or incidents occur per year and what impact they actually have on the environment is repeatedly asked. While many citizen groups and agency staff collected some information, there is no comprehensive Wisconsin-specific database of manure-related incidents available to help farmers and applicators prepare for and prevent manure spills.
