After drums unearthed on ex-Grumman site at Bethpage park, another call from town for full soil excavation
Workers clad in hazmat suits gathered Wednesday by a pit at Bethpage Community Park where six chemical drums were unearthed last week as Oyster Bay's supervisor echoed his call from a day earlier for a full soil excavation on the property where Grumman Aerospace dumped toxins decades ago.
A sign by the 10-foot by 25-foot pit read “Caution: Exclusion Zone” as the heavily-protected workers appeared to be handling samples and an excavator sat idle nearby — just feet from the recreation spot's shuttered skate park.
Last year the town sued Northrup Grumman, Grumman Aerospace's successor, criticizing the pace and thoroughness of a cleanup on the grounds stemming from the company's 2013 agreement with the state Department of Environment Conservation.
Contractors with Northrop Grumman found the 55-gallon drums about 7 feet underground while drilling a well Thursday to check an existing soil treatment system at the park, Supervisor Joseph Saladino told Newsday on Tuesday.
He said some of the drums had flammable chemicals and were unearthed between the 18-acre town park's shuttered ballfield and its fenced-off skate park. Much of the park, including a playground and indoor skating rink, remains open. Town officials said they closed the skate park in January as a precaution after Northrup Grumman's remediation work expanded in the area.
During a visit to the pit Wednesday, Saladino called on the DEC to mandate a full cleanup at the park by removing all soil and trucking it off Long Island. The supervisor also said a layer of clay had been found under the concrete-encased drums, characterizing the action as "another level of precaution" taken when the drums were buried.
Brian Nevin, an Oyster Bay spokesman, added that a plan to safely remove the drums from the pit is being developed.
The DEC said Tuesday it would do testing to determine the contents of the six chemical drums. The agency also said it would use “ground-penetrating radar, as well as subsurface drilling and sampling to determine the full nature and extent of contamination” and further investigate whether any more drums are buried on the site.
The DEC also said preliminary testing of the drums' content turned up “chlorinated solvents and waste oil/petroleum” — compounds the agency said were “consistent with known historic operations” of Grumman and the U.S. Navy at the location that are the focus of the ongoing remedial effort on the property.
Northrop Grumman officials said Tuesday they are working with the DEC to address the situation.
Between the 1940s and 1960s, Grumman used the land for disposal of wastewater sludges and solvent-soaked rages. Grumman donated land for the park to the town in 1962 and the park was a centerpiece of the Bethpage community for decades.
Then in 2002, contamination from polychlorinated biphenyls, or PCBs, was found in ballfield soil and the DEC — which regulates the site — discovered just how extensively it had been used as a chemical dumping ground. It was found to be a major contributor to the groundwater plume of carcinogenic chemicals that spread from former Grumman grounds and now is more than 4 miles long, 2 miles wide and 900 feet deep.
Separate from the 2013 agreement the DEC made with Northrup Grumman to address the ballfield contamination, the agency later made a half-billion dollar deal with Grumman and the U.S. Navy to contain and clean the plume.
But the DEC never confirmed a whistle-blower's 2016 claim that in the 1990s, chemical drums had been discovered and reburied at the Bethpage park.
Saladino told Newsday on Tuesday the discovery of the drums last week shows that account was true.
On Wednesday, Adrienne Esposito, executive director of Citizens Campaign for the Environment, said the discovery of the drums is “alarming.” She said the drums pose a threat to drinking water, regardless of what chemicals are inside them.
“A full examination” of the site is needed to uncover “more hidden dangers that threaten public health,” Esposito added.
Bethpage resident Khairun Rizvi, who lives just a few hundred feet from where the drums were found, said Wednesday she wasn’t aware of the discovery and expressed concern that neighbors weren’t notified.
“They should’ve sent us a letter,” said Rizvi, 31, noting that Northrop Grumman previously communicated with the neighbors about remediation work.
She said she noticed the skate park was closed during a visit to the park with her two children — ages 2 and 3 — but wasn’t sure of the extent of work being done nearby.
“I’m very shocked because it’s near where kids play,” Rizvi said.
