Hazardous waste produced by North Carolina State University researchers and dumped near the campus is contaminating the groundwater and bedrock to such a degree that the university has begun a multimillion-dollar project to pump out the contamination, The News and Observer, a newspaper in Raleigh, N.C., reported today. The waste, consisting of acids, chemicals, pesticides, and radioactive animal carcasses, was dumped from 1969 to 1980, and the landfill is on a federal list of the nation’s most polluted sites.
