DES MOINES, Iowa-- The Iowa Department of Natural Resources is investigating a southwest Iowa manure spill.The DNR says during a routine inspection Tuesday morning, inspectors noted a manure spill about three miles southwest of Lenox.
The property owner where the spill happened Monday says a malfunctioning plug caused manure to overflow from shallow below-building pits. An unknown amount of manure flowed overland to an tributary of a nearby river.
Tests showed elevated ammonia levels in the river, but no signs of a fish kill.
The DNR says it'll consider appropriate enforcement action.
