Hydrogen sulfide possible at Clendening Lake outlet

TIPPECANOE — The Huntington District of the U.S. Army Corps of Engineers has determined conditions exist in the outlet works area at Clendening Lake that could result in the presence and possible release of hydrogen sulfide gases.

Hydrogen sulfide is a colorless gas that can be recognized by its “rotten egg” odor. Symptoms of exposure vary depending on the level and duration of exposure. Low concentrations irritate the eyes, nose, throat and respiratory system. Asthmatics may experience breathing difficulties. Exposure to moderate concentrations can also cause fatigue, dizziness, nausea and headaches. Young children are at particular risk.

This problem is normally confined to the area adjacent to the outlet works and is not known to pose a problem to recreational users of the lakes. There is no indication that fish taken from these lakes pose a health risk if consumed.

The corps will monitor hydrogen sulfide levels at the outlet works. Project employees will take readings to detect any presence of hydrogen sulfife gases around the outlet works and surrounding areas.
