Kearny residents told odors may increase during landfill remediation

Neighbors of the Keegan Landfill in Kearny will have to suffer through offensive odors a little longer.

After hundreds complained about a hydrogen sulfide odor, the state Department of Environmental Protection says it’s working with the New Jersey Sports and Exposition Authority, which runs the landfill, to fix the problem.

But the rotten egg smell is likely to get worse before it gets better as contractors begin drilling wells next week to resolve the root of the problem, which the Sports and Exposition Authority says is likely caused by construction and demolition debris containing gypsum wallboard combining with excessive rainfall.

The state says hydrogen sulfide emissions are acceptable up to 30 parts per billion. After that, exposure to the gas can cause eye, nose, or throat irritation, nausea and headaches.

Air monitors outside the site detected levels far exceeding that regulatory standard on multiple occasions.
