An estimated 4,000 to 5,000 gallons of hog manure was released last week from a southeast Iowa pork facility, according to USAgnet.com. The accident occurred during application at a NPKK Pork facility in Washington County.

Mark Heiderscheit, environmental specialist with the DNR's Washington office who responded to the scene, said the manure applicator filled his tank and left to apply the manure. The stirring device used to combine solid and liquid manure for application was left on and shifted when it was unattended spraying the manure out of the basin.

The manure runoff followed a channel designed to divert rainwater from the lagoon, through a field and settled over a tile buried beneath the snow. The tile outlet begins an unnamed tributary of Indian Creek.
