ADVISORY - Orange County Increases Hydrogen Sulfide Monitoring

Orange County, FL - The Orange County Utilities Solid Waste Division has increased the frequency of hydrogen sulfide monitoring near the Orange County Landfill, 5901 Young Pine Road, Orlando, located in east Orange County off Young Pine Road between SR 417 and Innovation Way.

The new phase to measure hydrogen sulfide gas (H2S), which smells like sulfur or rotten eggs, began July 21. The first full week of data can be found at

Orange County Utilities will post weekly updates for a 90-day period. As suggested by the Florida Department of Health in May, three monitoring stations collect readings daily every 30 minutes, which is reflected in the data. The Florida Department of Health will review the data weekly and issue a report after the 90-day period.

The locations of the three hydrogen sulfide monitoring stations near the landfill – one mile northwest, two miles southwest and three miles northeast – were recommended by the Florida Department of Health. A map has been provided to help nearby residents identify the monitor closest to their residence.

Previously, hydrogen sulfide concentrations were being recorded using one mobile monitor at multiple locations surrounding the landfill around 1 a.m. and 5 a.m. on Fridays.

Hydrogen sulfide, which can be detected by the human nose at very low levels, has been a recurring issue since last fall. Consultants attributed the increased hydrogen sulfide creation to a previous practice of mixing household waste and construction and demolition debris (C&D).

The Florida Department of Health has a Frequently Asked Questions document about hydrogen sulfide on its website.
