From an article about indicted W.R. Grace officers:
"Grace executives also had reports or studies warning of the dangers of asbestos vermiculite exposure in 1977, 1980, 1981, 1982, the indictment alleged. At one point, it said, Eschenbach responded to one of the studies by writing in a memo: 'Our major problem is death from respiratory cancer. This is no surprise.'
"Despite having that information, the indictment said, Grace officials told the EPA in 1983 that there was no indication their products posed a substantial threat to human health.
"The company, knowing of the dangers from its product, provided vermiculite for a junior high school running track and as a base for an ice rink, the indictment said. It said Grace also sold or leased some of its contaminated properties to local residents for homes and businesses, for baseball fields and for city use."
