Hydrogen sulphide is a dangerous gas that is commonly found in swine operations. Reducing the amount of this gas is of great interest in order to keep the workers and animals safe. Hydrogen sulphide is water soluble so theoretically, spraying water during agitation may allow the hydrogen sulphide gas to return to solution and reduce airborne gas concentration. A commercial monitoring device for hydrogen sulphide was observed and compared to gas chromatography readings. Reducing gas levels from the agitated manure was successful when spraying water, though an additive mixed with the water had no effect.
