Report:
Lake Monongalia
While hydrogen sulfide is naturally occurring, a few practical steps can help reduce exposure and odor buildup:
-
Ensure good ventilation around enclosed spaces near water bodies.
-
Avoid prolonged exposure in low-lying or confined areas where odors are strong.
(Source: OSHA Quick Card - Hydrogen Sulfide).
This collaborative effort between MFCRWD and the City of New London aims to better understand the source, intensity, and impact of hydrogen sulfide emissions—and to help identify long-term solutions that benefit residents, businesses, and the local environment.
