Ten years after remediation was complete at the E.I. DuPont Superfund site in Newport, Del., the area had few options for reuse.
An 18-inch layer of soil capped a landfill where the toxic byproducts of pigment manufacturing had been dumped for decades. A barrier planted between the landfill and a nearby stream prevented the chemicals from migrating. The contamination no longer posed a threat to the environment or workers at nearby factories. But the land wasn’t being used.
The cap was protective only so long as nothing penetrated it, making building anything on the site virtually impossible.
“Redevelopment was a big issue for this site because you cannot dig,” said Dina Toto, remediation director for DuPont. “It was just sitting there.”
But in 2011, Tangent Energy Solutions approached DuPont with a novel idea to turn the barren land productive: solar panels.
Today, the 0.5-megawatt solar array at DuPont Newport has been online for almost a year, generating more than 1,000 megawatt-hours of electricity. Read more here.
