Work to continue at Beede site this summer

Few complaints generated by work at Superfund site

PLAISTOW — This summer will be an active one at the Beede Waste Oil Superfund site.

Cleanup is continuing at the 40-acre site off Main Street. Opening an on-site water treatment plant will be the next milestone.

“There’s a lot going on right now,” said Greg Howard, spokesman for the Beede Group. “But everything is on target.”

The Beede Group includes the companies deemed responsible for dumping hundreds of thousands of gallons of contaminants dumped at the site between 1920 and 1994.

The site was declared a Superfund site in 1996. Ten years later, 12 companies, including Exxon and Sears, agreed to fund a $45 million cleanup.

Recently, the cleanup is kicked into high gear.

In the last few weeks, the first phase of removing contaminated soil was completed. Hundreds of truckloads of soil were taken to a landfill in Rochester this spring.

“Our initial trucking is over,” Howard said. “We probably won’t be doing any trucking for at least a couple years.”

The next step is opening up the water treatment plant. It is expected to open by the end of the summer.

“We are working on the plumbing for the plant right now,” Howard said. “We have a few ways to extract the water, treat it and get the water back into the Earth.”

The system will remove the contaminated groundwater at a rate of 160 gallons per minute. After it is treated, the water is injected into wells or possibly into Kelley Brook. The process is expected to take between 15 to 30 years before New Hampshire groundwater standards are met.

A steam extraction system for contaminated deep soils is also in the final stages of being designed. The system is expected to be delivered to Plaistow this summer.

Town Manager Sean Fitzgerald said he was pleased with the work being done.

“It’s a safe and efficient remediation of contaminants,” Fitzgerald said. “We are hopeful that the remediation schedule will support a significant amount of progress and we can begin to think more optimistically.”
