A purchase and sales agreement has been signed for the property at 397 Washing- ton Street, the current site of the Battelle Memorial Institute campus.

The agreement was signed by Battelle and an organization that hopes to utilize the site as an educational institute. Selectman Shawn Dahlen said the buyers hope to partner with the University of Massachusetts Boston to use the site as an educational facility for marine studies.

Dahlen said the two organizations must do their due diligence in the next 60 days and all the papers are expected to officially pass this coming September. The hope, Dahlen said, is to have the campus operational by September 2015.

"There’s nothing as good as a university in town,” Dahlen said. “It will be great to have youth in there learning all about the environment and to use it as a major research area for undergraduate and graduate students.”

Katy Delaney, media relations manager at Battelle, also confirmed that Battelle has come to an agreement of the Duxbury facility. Out of respect for the partners in the transaction, and due to contractual obligations, she was not able to disclose any further details until the sale is final.

“We are working closely with the community and partners and believe this sale will be good for Duxbury,” Delaney said.

Jim Borghesani, spokesman for the purchasing group, said he believes the purchase will be a “wonderful thing for Duxbury.”

“The idea is that the site will remain virtually the same as it is now,” he said “The use would be in keeping with the historic use of the site.”
