State health officials have begun monitoring a facility that converts cow manure into natural gas after elevated levels of an unhealthy and flammable – but also naturally occurring – gas were recently detected.
The Colorado Department of Public Health and Environment reported excessive amounts of hydrogen sulfide were discovered through instruments readings at Platte River Biogas near Lasalle.
Hydrogen sulfide, informally referred to as “swamp gas” or “sewer gas,” is known for its odor that is similar to rotten eggs. The gas occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs, according to the National Institute of Health. It is also produced by human and animal wastes and results from the bacterial breakdown of organic matter.
