October 11, 1989: New York Times headline–Water-Main Break Spews Asbestos Into 8th Ave. “A water main burst at the intersection of Eighth Avenue and West 43d Street yesterday, sending asbestos-laden mud gurgling up the avenue and cascading down onto the IND subway tracks below, officials said.
The police closed West 43d Street and blocked off several lanes of Eighth Avenue while the City Department of Environmental Protection tested the mud to determine the level of asbestos, which was scattered from underground steam pipes.
A spokeswoman for the environmental agency, Tina Casey, said that the first round of tests showed varying amounts of asbestos, with one sample above ground containing 60 percent. Anything greater than 1 percent asbestos is considered hazardous, she said.”
October 11, 1988: New York Times headline–Science Watch; Less Lead in Rivers. “A decline in lead contamination in major American rivers has been found at two-thirds of 300 sites studied from 1974 to 1985, scientists at the United States Geological Survey have reported.
The report chiefly attributed the decline to a 75 percent drop in use of leaded gasoline in that period. The most rapid drop in lead content was recorded from 1979 to 1980, when use of leaded gasoline took its sharpest drop.
Preliminary analyses of more recent data indicate that the decline in lead contamination is continuing.”
