A $3.2 million project is nearly complete to add a new cell to a landfill managed by the Dubuque (Iowa) Metropolitan Area Solid Waste Agency. The new 10-acre cell has enough capacity to take in 440,000 tons of trash, which the agency estimates will last 60 years.
KWWL has the details:
The construction is a sophisticated process. The various layers of the landfill will help protect groundwater from being contaminated.
"They're kind of complex, they start with a compacted clay base, and then a vapor barrier that'll keep any moisture from getting down into the ground water, and then some rock and chewed up tires, and some drainage pipes, another layer to filter the chunks out," Jones said.
According to project leaders, it's also to protect the community. "The solid waste that has to be disposed of, has to be disposed of correctly. It's a public health issue."
