Iowa DNR investigates Butler County manure release
October 4, 2018 by Press release
Bristow, IA – Iowa Department of Natural Resources staff have investigated a manure spill caused by a broken water line in a hog confinement located about three miles north of Bristow.
An unknown amount of manure from an empty building traveled about a mile before entering a tributary of Parmentar Creek on Sept. 26. Field tests by DNR staff found slightly elevated ammonia levels, but not high enough to kill fish.
A cleanup crew from the farm stopped the flow and built dams downstream to contain contaminated water, which they pumped and hauled to apply on crop fields.
DNR did not observe any dead fish in the stream. DNR will continue to monitor cleanup and consider appropriate enforcement action.
