THROOP — Chemicals and particles that might waft through the air around Keystone Sanitary Landfill will face eight to 12 months of scrutiny from state and federal health agencies.
Staff from the State Department of Health and federal Agency for Toxic Substances and Disease Registry explained the health impacts study they plan to conduct around the landfill in the wake of its proposed expansion. Roughly 20 people from these agencies and the state Department of Environmental Protection were present at a Monday open house at the Throop Civic Center.
Air will be the main focus of the health study, as it represents the most likely pathway for any potential hazardous materials to enter the body.
“We want to tell them what’s in whatever they’re smelling,” Health Department deputy secretary for health planning and assessment Martin Raniowski said.
Through the month of May, the Health Department will review existing air and water data, mostly from DEP and landfill sampling efforts, he said.
From June to August, the Health Department will work with the state Department of Environmental Protection to take a new set of samples at multiple sites upwind and downwind of the landfill to better understand the chemical makeup of the air landfill neighbors breathe every day, he said.
The DEP brought its Mobile Analytical Unit, a sophisticated air quality lab in a van, to Throop for the event. The unit uses infrared light reflected off a gold array to measure methane, carbon dioxide, nitrogen oxides, metals and volatile organic compounds, spokeswoman Colleen Connolly said.
The mobile lab will begin sampling this week and may return to the area over the summer, she said. The DEP will supplement that monitoring with portable canisters, she said.
By fall or early winter, the Health Department will interpret the data and publish a draft study, which will be open for public comment. A final report will come in early 2016, Mr. Raniowski said.
The federal agency will examine the Health Department’s methods and findings and will have to sign off on the agency’s work, he said.
“Not only do you have state experts taking a look at this, you’re going to have a national set of experts looking at this,” he said.
Though the agency has not previously done such a study for Keystone, it has experience with health impacts studies regarding landfills. Its most recent were in 2013 at Chestnut Valley Landfill and waste management firm Tervita’s Westmoreland Landfill, both in Fayette County, spokeswoman Amy Worden said.
The Health Department will also examine potential underground carbon dioxide issues in Dunmore, as described in a Sunday Times article, and make recommendations to the DEP, Mr. Raniowski said.
“They’re still evaluating whether it needs to be looked into further from a health standpoint,” said Roger Bellas, who heads the waste management program in the DEP’s Wilkes-Barre office.
DEP officials did not have an immediate response to that story. Staff members from multiple programs, including hazardous sites cleanup and abandoned mine reclamation, are revisiting previous reports done on the issue and will likely respond by the end of the week, Ms. Connolly said.
