The Iowa City Landfill is once again open to the public following a series of fire-extinguishing efforts.
The “stir, burn, and cover” operation that began June 4, which started by stoking the flames to accelerate the consumption of fuel, ended Sunday as the smoldering remains were covered by a layer of clay.
The tires are expected to burn beneath the layer of clay for at least a few days, and during the time city officials are directing their efforts on containment.
“It could be several weeks,” Geoff Fruin, assistant to Iowa City manager Tom Markus, said Monday. “We’ll monitor the temperatures below the surface. We’ll be able to see any continued burning through surface burning or smoke that breaks the cap.”
The landfill may still occasionally produce smoke, and fire crews will remain on-site to monitor the situation, but no large plumes or flare ups are expected.
Researchers at the Iowa Flood Center are crossing their fingers that the Iowa City Landfill fire wont affect one of their sensors.
One of their mobile weather radar units is located at the landfill. So far it has avoided damage, but the Iowa Flood Center engineers will continue to monitor the situation closely. The radar provides rainfall intensity data for the Clear Creek watershed.
The Iowa Flood Center plans to clean the radar once the fire is extinguished.
