“If there needs to be a change, we will go back out and make the change,” Zimmerman said.
The groundwater at the two sites continues to be monitored following years of cleanup, according to DES representatives Andrew Hoffman and Kenneth Richards.
The cleanup at Ottati & Goss began with the removal of barrels in 1979 and treatment of soil in 2001. The cleanup finally ended in 2011, according to Hoffman, the site’s project manager.
“We have been in the monitoring phase for some time,” he said. “It looks promising.”
At Tinkham Garage, the soil and groundwater cleanup began in 1994 and the property was redeveloped several years later, according to Richards, the project manager.
Home Depot and Staples were constructed in 2003 and there is a 400-tenant condominium complex on another part of the site, in addition to other new homes.
“It’s a good example of how sites can be put back to good use,” Richards said.
