State officials say cleanup work continues at a southwestern Michigan dairy farm where liquid manure leaked from an open-air lagoon and spread into a creek and a river.
The Michigan Department of Environmental quality says workers at the Schaendorf farm are pumping manure-laden water from a country drainage ditch that flows into Bear Creek and returning it to the storage structure.
Department analyst Bruce Washburn said Tuesday that a valve failure between the lagoon and stormwater pipes caused the leak. The farm's in Allegan County's Monterey Township.
It's unclear how far the pollution has spread, but Washburn says manure's been spotted in the Rabbit River, 10 miles away.
He says the leak violates the farm's clean water permit and the state will decide what enforcement action to take.
