Just north of Rosendale, WI, in Fond du Lac County, an industrial dairy milks 8,300 head of dairy cows. The sheer scale of Rosendale Dairy is unprecedented in Wisconsin. The factory farm produces and stores over 90 million gallons of manure and wastewater each year; only the cities of Milwaukee and Madison produce more biological waste. Yet unlike these cities, the dairy stores the untreated manure in open lagoons before spreading it – still untreated – on area cropland. Additional impacts from the dairy’s operations include emissions of ammonia, a hazardous air pollutant, at levels exceeding the State standard for ambient air quality; withdrawal of nearly 90 million gallons of groundwater per year from on-site high-capacity wells; heavy truck traffic, estimated to be nearly 20,000 truck loads per year (an average of 53 trucks per day); and construction and paving of over 100 acres of formerly productive cropland.
