Northrop Grumman Corp. has installed the second of three permanent test wells in Bethpage south of the former Navy and Grumman Aerospace site to monitor groundwater levels and groundwater quality over time, Town of Oyster Bay and company officials said.

“These reviews are routinely performed to assess conditions and the effectiveness of groundwater remedial systems under the New York State Department of Environmental Conservation’s oversight,” Northrop Grumman spokesman Tim Paynter said in a statement.

Once testing is completed, results will be made available through the state DEC, he said.
Remediation is ongoing at and around the former manufacturing facilities where toxic groundwater plumes and soil contamination have been found.

The newest well was put in place on Feb. 14 at 16 N. Butehorn St., after an Oyster Bay town board vote granted permission for the installation in a town right of way, town spokeswoman Marta Kane said.

The installation request was made to the town by ARCADIS, an international infrastructure, water, environmental and building firm, on behalf of Northrop Grumman.
