Two areas of Hydrogen Sulfide concerns are being reported by the Huntington District of the U.S. Army Corps of Engineers.
Hydrogen sulfide is when sulfates are converted through microbial activity in the bottom layer of the lake.
This normal summer occurrence is typically confined to the adjacent outlet works and is not known to cause a problem for lakes users.
The Huntington District says there is a potential problem at Atwood Lake and Leesville Lake. H2S levels will be monitored.
Hydrogen sulfide is a colorless gas 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. Moderate exposure can cause fatigue, dizziness, nausea and headaches. Young children are at particular risk.
For public safety, the area immediately adjacent to the discharge at both lakes have been closed.
