ALLISON, Iowa (AP) — Officials are monitoring the cleanup of a fertilizer spill in northern Iowa that dumped hundreds of gallons of liquid.
The state Department of Natural Resources said Monday that an employee of the Farmers Cooperative in Allison was pulling a tank of 32 percent liquid nitrogen fertilizer on Thursday when a seam on the tank failed.
More than 800 gallons of the fertilizer spilled onto a city street. The liquid was then washed into a storm sewer that reached a nearby stream.
DNR officials later instructed the company on cleanup methods, including flushing the storm sewer with water and pumping it up. About 42,000 gallons of the water-fertilizer mix has been recovered.
Officials reported elevated levels of ammonia in the stream, but they’ve dropped. A number for Farmers Cooperative went unanswered Monday.
