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.
Hydrogen sulfide is also used or produced in a number of industries, such as oil and gas refining, mining, tanning, pulp and paper processing, and rayon manufacturing. It can be deadly at higher concentrations.
CDPHE started measuring air levels around Platte River Biogas after receiving reports of odors. The agency did not state when those reports were received nor when it tested the air.
