- Hydrogen Sulfide Detected at Leesville Lake: What You need to Know
Carroll county residents and visitors should be aware of a potential health hazard at Leesville Lake. The U.S. Army Corps of Engineers announced on June 16, 2025, the detection of hydrogen sulfide gas in the outlet works area of the lake. This colorless gas, known for its distinct rotten egg odor, poses potential health risks at certain concentrations.
The affected area, promptly adjacent to the discharge point, has been closed to the public as a precautionary measure. While the Corps of Engineers believes the issue is localized and doesn’t currently impact recreational users or fish consumption, they are actively monitoring the situation and will announce further closures if necessary.
What is Hydrogen Sulfide and Why is it in Leesville Lake?
Hydrogen sulfide (H2S) forms when sulfate concentrations in a body of water are unusually high. during warmer months, microbial activity in the lake’s bottom layers converts these sulfates into hydrogen sulfide gas.As water exits the lake,this gas is released into the air,potentially creating an unhealthy habitat in nearby areas.
Did You Know? Hydrogen sulfide is heavier than air, meaning it can accumulate in low-lying areas.
Potential Health Risks of Hydrogen Sulfide Exposure
The severity of symptoms from hydrogen sulfide exposure depends on the concentration and duration of exposure. Even low concentrations can irritate the eyes, nose, throat, and respiratory system. Moderate exposure may cause fatigue, dizziness, nausea, and headaches.
Individuals with asthma and young children are considered high-risk groups and should take extra precautions to avoid exposure. The CDC provides detailed information on hydrogen sulfide exposure and its health effects.
Pro Tip: If you smell a rotten egg odor near Leesville Lake, move to an area with fresh air immediately.
Safety Measures and Lake Closure Information
The U.S. Army Corps of Engineers has closed the area immediately adjacent to the discharge at Leesville Lake for public safety. This closure will remain in effect until the problem naturally resolves itself. The agency is continuously monitoring the area and will provide updates on any additional closures.
Here’s a summary of the key information:
| Location | Issue | Status | Action |
|---|---|---|---|
| leesville Lake (Outlet Works Area) | Hydrogen Sulfide Gas | Monitored | Area adjacent to discharge closed. |
What are the long-term implications of hydrogen sulfide in the lake?
The long-term implications are still being assessed. The U.S. Army Corps of Engineers is studying the source of the elevated sulfate levels to prevent future occurrences. sustained high levels of hydrogen sulfide can negatively impact aquatic life and water quality.
How can residents stay informed about the situation at Leesville Lake?
Residents can stay informed by monitoring official announcements from the U.S. Army Corps of Engineers and local news outlets. The Corps of Engineers will provide updates on their website and through press releases.
Hydrogen Sulfide: A Broader Context
Hydrogen sulfide is a naturally occurring gas found in various environments, including sewers, swamps, and volcanic areas. It’s also a byproduct of certain industrial processes. While frequently enough associated with unpleasant odors and health concerns, hydrogen sulfide also plays a role in various biological processes at low concentrations.
The presence of hydrogen sulfide in lakes and other bodies of water can be influenced by factors such as agricultural runoff,industrial discharge,and natural geological formations. Monitoring and managing sulfate levels in watersheds is crucial for preventing the formation of hydrogen sulfide and protecting water quality.
