Orange County officials are investigating a nasty odor that seems to be hovering above a popular new playground in Monroe.

They have an idea of who might be responsible for the smell, but said that party is not helping solve the odor issue around Airplane Park.

Orange County is seeking engineers to help trace the odor, county attorney Richard Golden said Friday.

Golden said the odor is likely coming through manholes near an underground nexus of multiple sewage lines from nearby municipalities, and county leaders are looking in the direction of the village of South Blooming Grove.

He said village leaders have refused to use a special treatment to control sewage odor before it leaves the village and flows toward a treatment plant in Harriman.

Monroe resident Leah Scholl said sometimes it is hard for her children not to notice the odor.

"They'll get a little nauseous," she said. "They get a little sensitive to it even more ... It does get little too intense."

State Sen. James Skoufis sent a letter last week to the New York State Department of Environmental Conservation asking the agency to investigate.

"The problem point is county-owned. The origin point is South Blooming Grove," Skoufis said during a Zoom interview Friday morning. "That's why we're reaching out to the DEC, because I'm sick and tired of this back-and-forth."

As she pushed her daughter Karin on the swing, Lara Torello said the odor Friday was not as pungent as usual.

She said she can tolerate a whiff of odor sometimes, but is looking to her local government to make sure the problem does not grow.

"I certainly hope it's something that can be fixed because I think we have a lot of fun years here ahead of us, but that would be a shame if it were to become overwhelming."

South Blooming Grove officials have not responded to multiple inquiries seeking comment for this story.

A DEC spokesperson told News 12 late Friday there are signs South Blooming Grove could be the source of the odor.

"The Orange County Sewer District ... advised DEC (in 2024) that hydrogen sulfide gas is present in the sewer system and can be traced back to influent flows from the village of Chester, town of Chester, and village of South Blooming Grove," a spokesperson wrote. "Ambient sampling conducted on Aug. 11 and 15, 2025, showed levels in the vicinity of Airplane Park well below the hydrogen sulfide air quality standard. DEC is currently reviewing the report to determine next steps."
