ODEBOLT — A tanker carrying ammonium thiosulfate, a liquid fertilizer, tipped over in Odebolt Friday morning, according to the Iowa Department of Natural Resources (DNR).
The tanker, owned by Northland Transportation Inc., was carrying about 4,340 gallons of fertilizer and was bound for a bulk plant in Boone.
The DNR said it was unknown how much of the fertilizer leaked from the top fill port before the leak was stopped and contained. Some of the fertilizer ran into a small tributary, through a culvert and flowed through town to Odebolt Creek, DNR staff said.
Water quality was tested at several places in the tributary and elevated levels of ammonia were found, but the DNR said they did not detect ammonia downstream in the creek. There are no fish in the tributary, and no dead fish have been found, they said.
The company will pump up spilled fertilizer and water trapped behind the culvert.
The DNR said it will monitor the cleanup and consider appropriate enforcement action.
