Dive Brief:
- Elevated levels of hydrogen sulfide, a dangerous gas, is causing heath concerns among those who live near the Bridgeton landfill near St. Louis, Missouri.
- The chemical compound was present in levels which exceeded "health-based guidelines" during fifteen days in the past four weeks, according to a report from the health department.
- It is thought that despite of the alarming rate of gas present, the hydrogen sulfide levels are within the safe zone and should not pose a health risk at this time.
Dive Insight:
In its concentrated form, hydrogen sulfide can cause death. The volatile organic gas is produced by decaying matter. The motors at the landfill measured other sulfide compounds in addition to the hydrogen sulfide, which can alter the readings. More precise monitors excluded the other gasses and found that the levels aren't a serious health threat at this time. The Bridgeton landfill has experienced ongoing troubles, such as dangerous underground fires, which prompted health concerns within the surrounding community.
