EPA H2S Calculator app for iPhone and iPad

The H2S application is designed to be used by landfill owner/operators and state or local regulators to help anticipate and reduce hydrogen sulfide emissions from disposal sites that accept significant amounts of construction and demolition debris, including debris from Hurricanes Harvey and Irma, as a number of landfills are located in environmental justice areas.

Emissions of H2S create odors and at certain levels can present public health threats. Hydrogen sulfide is easily converted to sulfur dioxide, and the H2S application allows landfills to model their emissions and choose different best management practices to increase their efficiency of air control devices and to improve the neighborhood ambient air quality. There is no similar application on the market at this time.
