Officials want Dartmouth College to resume lab waste cleanup

New Hampshire environmental officials have asked Dartmouth College to reopen cleanup efforts at a Hanover farm where laboratory animals were buried in the 1960s and 1970s.

The Valley News reported that remediation work at the Rennie Farm will include testing for radioactive substances.

In 2011, a contractor hired by the college excavated and disposed of thousands of pounds of animal carcasses laced with industrial chemicals and radioactive isotopes that had been buried there. The contractor told state regulators in a letter in June 2012 that the work had been completed.
